Road safety from the lithium-polymer batteries started

Car GPS for everyone as more and more accepted by car people always want to have an Laptop Battery excellent tool for navigation, as it relates to your driving safety, and any relationship to its security? That is its battery.

At present, the vast majority of GPS brands were used in lithium-ion batteries. Compared to other rechargeable batteries, lithium-ion battery with a voltage higher than that of high energy, charge-discharge and long life, no memory effect and pollution-free, fast charging, low self-discharge rate of the advantages of entering the market in 1991, shortly get consumers favor. Now, notebook computers, mobile phones, digital cameras, MP3 and other digital products mostly equipped with a lithium-ion battery. However, the rapid development of related industries at the same time, the safety of lithium-ion battery problems are still disturbing for people.

June 19, Jinta County, Gansu Province, a welder in operation, the mobile phone battery exploded, resulting in broken ribs and punctured his heart and died; canon NB-5L battery Guangzhou occurred within one day two mobile phone battery explosion; even IBM laptop battery explosions have occurred in the incident ... ...

Lithium-ion battery safety accident occurs mainly by the electrodes and electrolyte between the chemical reaction. Traditional lithium-ion battery design requirements of organic substances in a lithium-bearing elements, and packed in a metal box, if this box will appear very unstable leak situation. In fact, Apple, Dell, Fujitsu, Hitachi, IBM / Lenovo, Panasonic, Sharp, Toshiba, Gigabyte and Sony have developed their own battery recall of activities involving the recovery of the number of batteries are close to canon BP-511 battery the 10 million mark. If you're more concerned about the incident, please refer "Notebook User Must! Li-ion battery recalls great summary of" this article.

After a massive recall of laptop batteries in 2006, after the nightmare, Sony has rushed to adopt a safer lithium-polymer battery technology. According to dailytech.com site reported that Sony Electronics president StanGlasgow at the end of 2006, said he thought notebook vendors may soon use lithium polymer battery technology to replace the currently used lithium-ion battery technology. Glasgow said that may be due to the design and manufacture of batteries small error, we can not add to the lithium-ion batteries for more energy. After a lithium-ion battery technology after the events of Sony batteries might be more willing to adopt a more secure and more advanced lithium technology.

Lithium polymer and lithium-ion batteries compared to what different?

Lithium-polymer battery (Li-polymer, also known as lithium polymer batteries), with a high energy density, more compact, canon NB-2L battery ultra-thin, lightweight and high-security, and many other obvious advantage. In shape, the lithium-polymer batteries with a thin-oriented features, you can meet the needs of a variety of products, made into any shape and capacity of the battery; in security, the outer is plastic packaging, unlike liquid lithium metal shell, internal quality hidden through the outer deformation immediately displayed in the event of safety problems, will not explode, it will only bulging. It is reported that Apple has started in their own products, the use of lithium polymer batteries. Future MacBook and MacBookPro laptops will be the use of such new battery.

Added back, the current in-car GPS brand which uses a lithium polymer battery it? Only Mio (Mio www.mio.com.cn), and Routon (Lu-teng www.routon.com).

Routon is the industry's emerging brand, attached to fine-lun electronics, GPS uses the brand capacity of 1700mAH lithium-polymer battery canon NB-1L battery is about more than the market a lot of commonly used 1300mAH. In the use of lithium polymer batteries, GPS weight, volume, time, and the use of secure areas have been greatly improved, of course, because of these changes, the cost of natural lithium polymer batteries Lithium-ion batteries much higher than the At present, only high-end mobile phones and notebook computers will use. However, when compared with the safety of your trip, which in turn could be considered what?

Imagine if you are driving, because of GPS battery explosion an accident, then it must surely be fatal in nature, ranging from serious injuries, while in their lives and even affect the safety of other vehicles. Although this is a security risk, but by no means an alarmist, Sony Digital Camera Battery because the probability of the accident is small, in the event they usually can not be predicted. So, like the way this brand Teng, even if the increase their costs, it must be responsible for the safety for consumers.

New type of electric bus Lithium iron phosphate power battery car towards highway

Recently, the Science and Technology Division organized 16 fellow high-tech experts and financial experts in Jilin Province, Laptop Battery Changchun City, the annual national scientific and technological support to the 2009 Plan key project "Lithium iron phosphate battery materials and power the industrialization of research" conducted a project feasibility argument. Lithium iron phosphate power battery R & D team from the Northeast Normal University, after many years of technology research developed, this argument indicates that with this new type of high-energy lithium-ion battery of new energy vehicles will be put into the market, with "10 City, 1000 cars "as the representative of the new energy vehicle demonstration and application projects will be further promoted.

To recharge a battery Province, 60 liters petrol

The Jilin developed lithium iron phosphate power battery is for the lithium iron phosphate cathode materials, new high-energy lithium-ion battery, sony NP-FM51 battery lithium-ion battery separator, as well as lithium-ion battery management system for the industrialization of key technologies, Jilin Province, Li-Ion Battery Materials Science and Technology Innovation Center Dr. Xie Haiming on "China's energy newspaper," told reporters: "Lithium iron phosphate battery is in the past the battery cathode (ie, cathode) material replacement Lithium iron phosphate, this form of energy conversion, with a strong energy-saving efficacy. "

Worked out an account: Lithium iron phosphate batteries to recharge a battery, and sustainable travel over 300 kilometers and the cost per 100 kilometers is about 10 dollars or so, the charge is also only 20 minutes, but needs 20 liters in accordance with 100 km gasoline, then it Lithium iron phosphate batteries to recharge a battery can be saved for at least 60 liters petrol.

Moreover, there are many hybrid cars uses a nickel-metal hydride batteries sony NP-FM50 battery, a maximum of only 500 charge and discharge, and "Lithium iron phosphate battery can easily reach 2,000 or more times," Dr Tse said, "and it is only a few percent loss . "Dr. Xie said, with the quality of lead-acid battery is the" new for half a year old for six months, another half a year to maintain the maintenance, "can only use a maximum of 1-1.5 years, while the lithium iron phosphate batteries are charging and discharging of vehicles every day, you can do not worry about running in 2078 can not be recharged into the battery power.

The study also broke through the balance between capacity and weight of the technical difficulties. "Common motive power to be applied to a CMB or the bus, you may need tens of thousands, while the lithium iron phosphate batteries just over 100 pieces." Dr Tse said. The development of lithium iron phosphate battery with large capacity, reached the 300-400Ah, general lead-acid batteries for electric bicycles equipped with the weight of the vehicle is not exceeded under the conditions of its battery capacity up to 12Ah. And, at this time the weight of lead-acid battery has reached 13 kg,sony NP-FR1 battery while the same capacity of lithium iron phosphate battery weighs only 5 kg.

With the Mercedes-Benz, Toyota battle for market

As the lithium iron phosphate material without any toxic and harmful substances, whether in production or use and will not cause any pollution to the environment, it has been recognized as the world's energy-saving environmentally friendly batteries. Lithium iron phosphate with the unit price is not high, and long service life, cost, naturally become the lowest of several materials, so the market prospect is very wide. This has prompted international auto giants moving into Lithium iron phosphate battery market: in 2009, Mercedes-Benz announced that it would join the Li-ion battery hybrid research and development production lines. As early as in early July 2007, Toyota says that the company is working to develop a miniature of pure electric vehicles. Key technologies for the battery, Toyota set up a "battery research department" specialized R & D in terms of performance beyond the traditional lithium-ion battery new battery, sony NP-F550 battery but lithium iron phosphate is likely to be Toyota's plug-in power transition, vehicles can not bypass a technical.

Dr Tse said: "China's lithium resources accounted for 80% of the world, make good use of materials inherent advantages of the acquired technology research and development, China has the ability to seize the future of lithium-ion market." Coupled with the pessimistic outlook of the world automobile industry may be leading professionals in the flow of new energy vehicles in China provides a reserve of talent opportunities. In such a period of strategic opportunity, "It should be will have proven technology toward the industrialization of the sample stage is mass-produced and put into the market phase." It is reported that Jilin has 50 Lithium iron phosphate battery car off the assembly line and put into use.

Multi-party support can not be less

Kyrgyzstan auto industry analyst with the North produced a letter that was sweet: "In support of the government industrial policy direction is clear,canon NB-5H battery relevant supporting policies full circumstances, social resources and will to a great collection of new energy vehicles, technology and cost constraints, bottlenecks the problem will go away. "

In the "Lithium iron phosphate battery materials and power the industrialization of research" project feasibility study, the Science and Technology Group believes that: The project preparatory work for a solid, talented people have obvious advantages, has made an important initial results. The implementation of the project will be to train a group of power battery fields of scientific research and industrialization of innovative talents to form a high-level research team.

But to really put on the market, Lithium iron phosphate cell vehicle to promote canon NB-4L battery the support of the parties can not be separated. At present, China is pursuing, "10 City, 1000" new energy vehicles project aimed at the 13 pilot cities, the public transport sector to promote new energy vehicles, which is the "Tenth Five-Year" period "863" National High-tech development plan Lithium iron phosphate batteries provide a marketing opportunity and financial protection policies. May 26, Jilin Province, Chang Han Changfu the special meeting hosted by the provincial government, also said that Jilin will take effective measures to expedite the development of new energy vehicles, promote energy conservation and reduce emissions to Jilin Province to build a national automotive research and development of new energy production base. At the same time, Jilin Liaoyuan working with the FAW Group and the local auto companies to cooperate to promote hybrid vehicles operating Changchun and canon NB-4L battery Liaoyuan City line demonstration of pure electric vehicles, operating line demonstration

The new round of economic stimulus package clear: involving seven major industries such as electric vehicles

New energy, new materials, information industry, new medicines, bio-breeding, energy saving Laptop Battery and environmental protection, electric cars - the seven strategic emerging industries will be China in the context of the current round of the international financial crisis, following the 4 trillion of investment and Ten Industry Promotion Planning After the new round of economic stimulus packages.

As China's economic and social development after 30 years of reform and opening up a new stand on the crossroads of the "industrial nation" a new historical stage, China's road of industrialization is also facing new options, and has been developed from the the development process point of view, from an economic power into an economic power, China must give the direction of new industries locate and make effective implementation and enforcement.

New program to stimulate the economy:

Prime Minister and the experts from the seven new industry business

September 22, 2009 to 23, Premier Wen Jiabao Casio Digital Camera Battery chaired a forum on the development of three emerging strategic industries, has engaged the 47 Chinese Academy of Sciences and Academy of Engineering, Professor of universities and research institutes, experts, business and industry associations, on the new energy, energy-saving environmental protection, electric cars, new materials, new medicines, bio-breeding and information industry, the development of industries such as seven observations and recommendations in the following notice published in the meeting, the seven major industry has been described as a "strategic emerging industries. "

Later, on November 23 conference held in the capital, technology, Premier Wen Jiabao delivered a speech entitled "Let the science and technology to lead China's sustainable development" speech, which once again made the above-mentioned seven major industries more specific interpretation, while on the oceans, deep space and Earth's resources, the issue also made use of unique insights.

These areas together constitute the future development of China's emerging strategic industries of science and technology research Casio Digital Camera Battery road map.

Currently, the National Development and Reform Commission being a "strategic development plan of new industries," the formulation, which will be China in the context of the current round of the international financial crisis, following the 4 trillion of investment and ten industrial revitalization plan to stimulate the economy after a new round of the program.

Chinese Premier Wen Jiabao at the forum said that "the development of strategic and emerging industries, is based on the current tide over the crisis, focusing on the level of long-term major strategic choice."

Of course, China is so special, so an innovative targeting mainly industrial planning, how to give the regional development imbalance in the country already has brought a balanced development opportunities, how to ensure that every year in increasing employment needs, will be have to consider.sony DSC-T7 battery In addition, the healthy and efficient development of these industries, will need to have "strategic decision-making reserves, technological innovation and reserves, leading talent reserve, industrial reserve" and so on.

Therefore, such a new industry by China's rise and the economic restructuring of the strategic choice to give more hope that resistance is bound to Club Road, and long. However, under the passive reform and crisis is different from seeing new opportunities and actively promote the idea of reform, under the situation, the corresponding change in the space of the system reasonably be expected to.

Perhaps many people will have questions: What kind of industry can be selected as a "strategic emerging industries"? In response, Premier Wen Jiabao has a clear and scientific answer: One, the product must be stable and promising market demand; 2 is to have a good economic and technological benefits; third is to promote the emergence of a number of industries.

Taking into account including overseas capital, social capital, including a number of investments in emerging industries such enthusiasm, along with sony NP-FE1 battery the development of new industries and strategic planning, a wealth of new stories will be born. So attractive, but also so colorful, but the state could pass the appropriate institutional arrangements for private capital investment in these warm and Industrial Planning for a good docking, making these funds become a strategic driving force for development of new industries, cause for concern.

However, taking into account the new strategic planning of new industries to provide policy sony NP-F10 battery and financial support around the country a new round of strategic competition in emerging industries will expand.

K-Swiss Auto Net: We know that winning record with the Daimler Motor Company built an electric vehicle lithium-ion battery joint venture. Now you in the progress of lithium batteries? Cost has always been plagued lithium batteries and electric vehicles an important factor in the market, you think they should do to overcome the cost problem?

Wu Hao-Ze: Our joint venture with Daimler is actually produced by lithium battery components (including positive, negative, battery separator, etc.), not a battery pack. One month lithium battery, including hundreds of single cells. In the cell membrane, we have developed a very special product, called SEPARION ®. Li-ion battery industry development prospects of a great, but we are still in the initial stages of development. Daimler will our batteries used in its plans in the third quarter of 2011, since the end of the listing on the Smart series of electric vehicles, so we still have enough time to optimize production. We hope that through a larger production scale to reduce its costs. But now talk about its production costs, FUJIFILM NP-60 battery would be premature.

K-Swiss Auto Net: To achieve a larger scale of mass production, you will need to develop Daimler other than the customer?

Wu Hao Ze: Yes. Daimler joint-venture with our non-exclusive. In the automotive industry, we not only Daimler's Smart family for the supply of electric vehicle batteries, also with some other large international enterprises, such as GM Opel cars and the French car prices, as well as some of the production of a lithium battery supplier If mainland China Group, to cooperate. In addition, our products are used in industry, for energy storage, in this context, Siemens is one of our clients. We hope to achieve this cross-industry application of advanced technology.

K-Swiss Auto Net: winning record industry group of chemical products in the promotion of automotive lightweight and energy-saving and emission reduction have any effect? FUJIFILM NP-40 battery Can give you a few examples?

Gregor Hetzke: one is the polymer product, has been widely used in the car. Such as our PMMA (polymethyl methacrylate), not only can be used for public lighting field, but also more and more used auto body parts. Body from the iron and steel materials, the transition to a polymer material, which is an important part of its light weight.

Another very interesting application of PMMA is in the train windows. Compared to glass, PMMA is a more ideal material because of its translucent nature better, stronger anti-aging properties of materials is the windows can be 20-30. Moreover, the use of PMMA in the windows instead of glass material, can reduce the weight of each vehicle as much as 20 kg.

In addition, we have some high-temperature resistant polymer products such as Nylon 12, PEEK (polyether ether ketone), can be used in automobile engine parts.

In our view, a new generation of vehicles (developed out of the next 5-7 years), the polymer materials, casio NP-40 battery the application will be multiplied.

Wu Hao-Ze: We have many other products can help to reduce vehicle fuel consumption and carbon dioxide emissions. For example, our PCS (polysilicon) for automobile tires, which reduces the rolling resistance, thereby reducing fuel consumption and carbon dioxide emissions.

K-Swiss Auto Net: winning hit in the parent company's R & D activities, research and new product research to create a total of 55%, application development and improve the processes together account for 45%. In China, the winning hit for the R & D (especially for products used in the automotive industry) is not a major is the application development?

Dr. Yu sea: multinational research and development in China, casio LB01 battery the first step, are generally applied research and development. Win record also do so. But we began last year is gradually transferred from the application of basic research and development of research and development. To do so, mainly because we have to localize our technology, this is our development in Greater China, a starting point. Win record an annual increase of 300 patents, I think in the future we will be in China, there are a lot of patents each year. The automotive industry, we have also organized a Chinese automotive industry group. Their main task is to promote car-related cooperation between the various business units to strengthen technical exchanges, joint development of China's automobile industry casio CRV3 battery to help technology and business.

Lithium Battery Industry Analysis

Recently, according to statistics, the global automotive lithium battery production enterprises are Panasonic CGA-S303 battery mainly over 20, while Japan is walking in the governments around the world, there is the United States, A123, Johnson Controls (JohnsonControls); China's BYD, South Korea's LG Chemical , but only in Japan there are Toshiba, Hitachi, NEC (NEC), GSYuasa, Toyota Motor and Matsushita Electric Industrial of the combined company PanasonicEVEnergy related businesses such as 10 came to our house.

Investment Advisor in the new energy automotive industry researcher Li Sheng-mao believes that the current lithium batteries have been gradually to electric bicycles, electric vehicles and other areas. As the global demand for lithium battery applications, the continuous expansion every year. The current global automotive Li-ion battery industry is entering phase of rapid development,Panasonic SDR-S100 battery the battery manufacturers engaged in a fierce battle for market competition.

Investment Consultants in industrial research center data showed, according to the current hybrid electric vehicles use nickel-metal hydride battery is almost mostly manufactured by Japanese companies, Japan's Toyota and Honda dominate the hybrid electric vehicles and related technologies, 2 companies in the world market share of over 85%.

As the car used in the development of mobile battery will take a very long event, so car manufacturers and battery of cooperation between enterprises is of paramount importance. In Korea, Hyundai Motor and LG Chemical Co., Ltd. have jointly developed co-operation more than five years. In July this year, the upcoming Hyundai Elantra LPG hybrid electric vehicles. In addition, LG Chemical Company has become the U.S. General in the built-in hybrid electric vehicle batteries used in development cooperation partners, Panasonic CGR-S006 battery the two companies are to proceed with joint development.

As a result, South Korea and Japan to compete in the technical aspects of the present white-hot. Japan from 1992 to 2001 decade, in the storage of electricity used in lithium batteries and small electric cars that use lithium-ion battery development has invested 166 billion yen. From 2002 to 2006, in fuel cell vehicles use lithium-battery development has also invested 53 billion yen. This year, the Japanese automakers, battery companies and other related areas of business development with the release of the second-generation mobile automotive battery development program. Since last year, 2011, will be the second-generation vehicle battery systems development, 110 billion yen in R & D goal is to develop a performance 50%, the price is only one-seventh of a new battery.

To Hyundai Motor Company and LG Chemical Company as the main force of the Korean companies from 2004 to five years, as a second-generation battery-powered industry, a growing part in the hybrid electric vehicle with a high output power lithium battery development has been invested ₩ 16,000,000,000 budget. In addition, the decision by the Department last year, South Korean knowledge-based economy in 5 years, the built-in hybrid electric vehicles to use the mobile battery and related systems development assistance for ₩ 40,000,000,000, and in 2013 began to mass production. At the same time, the current government will pro-environment, car industry, selected as the new pillar industries. Government's objective is to automobile production in the future in the green area,Panasonic CGA-S006 battery one of the world's four major powers.

Accordingly, the investment adviser, said auto industry analyst with Li Sheng-mao, the electric vehicle's core technology is the power battery. Electric Vehicle urgent need of industrial development of high-power power battery support, the future, car companies want to occupy the field of electric vehicles in the global market and to take the lead in seizing the opportunity, first and foremost issue is resolved before the second-generation car battery production.

According to Deutsche Bank research shows that vehicle the following 10 companies most willing to work with companies to develop automotive lithium battery: 1) JohnsonControls-Saft (the United States and France, Johnson Controls and Saft joint venture); 2) A123 Systems, Inc. (from the Massachusetts Institute of Technology , General Electric and other investors to set up the company's group of co-operation with the mainland); 3) LG Chemical (The company has subsidiaries in the United States CompactPower); 4)Panasonic CGA-S003 battery EnerDel (Ener1 and Delphi joint venture); 5) AESC (Nissan and NEC joint venture); 6) PEVE (a joint venture between Toyota and Matsushita); 7) GS Yuasa; 8) Hitachi; 9) Sanyo Electric; 10) Samsung.

The authority of alternative energy sites GreenCarCongress editor MichaelMillikin predict the future, vehicle manufacturers of lithium batteries the "big three" are: 1) PEVE, 2) AESC, 3) LG Chemical. Most of these suppliers have contracted with at least two vehicle companies, while the world's major automobile companies are usually several options for at least two lithium battery supplier.

Investment Advisor in the new energy automotive industry researcher Li Sheng-mao pointed out that the research can be found from the above, at present, the Japanese lithium battery suppliers in the global market indeed account for a large advantage. However, in recent years, China Li-ion battery technology in the car has also been caught up BYD regarded leader in the industry, and was most recently the car has just been reached with Germany's Volkswagen electric cars lithium battery supply agreement.

"Lithium battery is a relatively good performance of the battery, the global electric vehicle batteries are mainly used lithium batteries. In China, the production of lithium batteries also have the advantage." Jia Xinguang, senior automotive industry experts said, "The reason why the development of electric vehicles is not up is mainly subject to the battery. Therefore, the battery can not be separated to develop on this core technology. "currently the best hope to obtain the industrialization of the battery technology is lithium iron phosphate battery (LiFePO4). China's major iron phosphate lithium battery Panasonic CGA-S001E battery manufacturers and the Wanxiang Group, BYD, BYD one of the world's cobalt lithium battery market of 30%.

China's development of electric cars is most difficult to charge users, unlike Europe and the United States, has an exclusive resident garage can be used. Jia Xinguang said that at present the domestic establishment of hundreds of thousands of gas stations to spend a few decades, but it is impossible to spend a few decades to build charging stations. Therefore, the urgent need for charging, charging the solution needed to support national policies and infrastructure construction.

Miao Wei, vice minister of industry, said the letter, but in the long term, large-scale commercialization of electric vehicles to promote the need for battery industry and power grids, municipal infrastructure, and many other supporting facilities.

Deputy Minister of Finance Zhang Shao-chun in the electric car Panasonic CGA-S002 battery industry development forum, said the revitalization plans in the automotive industry has made it clear in public transportation, rental and sanitation and other priority areas, including pure electric vehicles, including the promotion of energy-saving and new energy vehicles, and identify 13 pilot projects.

It is understood that most of these cities, the government has produced a specific implementation plan, and started to cooperate with the automobile business. The FAW, Dongfeng, BYD, and other enterprises have adjusted their development strategies, increase new energy and electric vehicle research and development input.

"Of course, in the promotion of public transport and other priority areas of research and development production of large enterprises, they can through the government to buy." But in the long run, Jia Xinguang think that for China to achieve a pure electric vehicle commercialization of age, there is still a long way to go . Commercial implications, that is, Panasonic Digital Camera Battery sales market is accepted by the market, rather than rely on government subsidies to the policy-driven.

Of which contains a market position on the issue. Every year over 10 million sales of electric bicycles, and its complete industry chain is expected to extend to the field of pure electric vehicles. Jia Xinguang pointed out that in Europe, electric vehicles are mainly two-seat, and a number of small businesses are doing, while positioning our country in this respect is not the case. "We are targeting a market electric vehicles should be those riding a bike, but can not be targeted to those who ride high-end cars. After all, electric cars get replaced by BMW Mercedes-Benz is reluctant to energy."

"Management can not be overlooked issue is a big problem." Jia Xinguang told reporters that the state licenses for the production of pure electric vehicles, the issuance of the policy is not introduced, there is no corresponding measures to manage. This is likely to lead to market confusion.

Obviously, a pure electric vehicle for China to achieve the era of commercialization Panasonic Digital Camera Battery is still some way to go.

Non-ferrous metals lithium carbonate industry is expected to create the myth of power battery plate

Non-ferrous metals lithium carbonate industry is expected to create the myth of power battery plate

That year the German government in order to develop the solar energy industry to the relevant manufacturers to provide substantial financial subsidies, Laptop Battery not only created a generation of China's richest man, but also created a Chinese solar cell and polysilicon plates for several years large cattle myth; Now the Chinese Government to the new energy vehicles to provide large financial subsidies to , is expected to bring new energy and power of motor vehicles and the myth of the battery plate.

General speaking, the new energy automotive industry chain of roughly be divided into three parts: the upper reaches of a non-ferrous metal raw materials, there is the middle vehicle power batteries and battery materials suppliers manufacturers, downstream vehicle manufacturers.

The new energy automotive industry chain, the core part of the new energy vehicle manufacturing, power battery and power battery materials, among which lithium iron phosphate power battery cathode materials, the most promising investment opportunities, while the key raw material in lithium iron phosphate is lithium carbonate, lithium carbonate derived from the mineral resources, in the nature reserves are limited, with strong regional and scarcity, are scarce resources. Thus, in the new energy automotive industry chain, Sony CCD-SC9 battery lithium carbonate becomes the strategic importance of resources is particularly prominent.

First, lithium carbonate industry status quo

The status quo of the global lithium carbonate industry, resource threshold high, capacity is highly concentrated. As of the end of 2007, the global lithium carbonate demand for a total of about 93,000 tons, a major international manufacturers have Chile's SQM, the United States and Germany, Chemtall total FMC annual capacity of 78,000 tons, accounting for 80% of global market share. Large-scale production of lithium carbonate as the enterprise must have reserves of lithium resources are more abundant in salt lake resources, mining rights, which makes the resources of the industry with higher barriers to entry; the other hand, the vast majority of the world's resources are high-magnesium salt low lithium-based , and from high-Mg low-lithium brine separation of lithium carbonate in the purification process technology is very difficult to master prior to these technologies is only a few hands of foreign companies, which makes lithium carbonate industry, but also provides many technical barriers.Sony CCD-TR2 battery Therefore, lithium carbonate has created the industry's global oligopoly structure.

Lithium Salt Lake in the independent R & D, which provides technology and production process of magnesium on the basis of a number of large industrial enterprises in China in recent years in the depths of the Qaidam Basin Zabuye Salt Lake and start building lithium carbonate, magnesium hydroxide and other chemical products production base. The current domestic production of lithium carbonate enterprises mainly in Tibet, mining, CITIC Guoan, Western Mining Group, Qinghai Salt Lake Group, the four companies, while the Tibetan mining and CITIC Guoan has accounted for the vast majority of them, the two companies in 2008 Lithium Carbonate Total output of more than 4,000 tons.

Statistics show that the hinterland of Qinghai-Tibet Plateau is located in the Qaidam Basin, rich in potassium, sodium, magnesium, lithium, boron and other mineral resources, including magnesium chloride 3.1 billion tons, accounting for about 99% of the country to maintain reserves;Sony CCD-TR3 battery lithium chloride nearly 14 million tons, accounting for 83% of the country to maintain reserves. In early 2007, Qinghai CITIC Guoan Technology Development Corporation's West taijnar hu-ton lithium carbonate project formally put into production in the Qaidam Basin, the West Lake taijnar become an important production base for lithium carbonate.

Second, lithium carbonate industry bottlenecks

At present, the global lithium carbonate production capacity is still low, the production costs are high, not really large-scale mining extraction, the company is still looking for more economical and reasonable mode of production, currently hamper the development of lithium carbonate industry is still the biggest problem is the production process technology. In the short term, Tibet, mining and technology in the production of CITIC Guoan is still inadequate, annual output is only 2,000 tons, respectively, representing a lower percentage of main business income is difficult to drive performance increased significantly.

Chinese Academy of Sciences, said Li Jian, researcher, Salt Lake extracting lithium, magnesium technology, to mention a "bottleneck" and gradually Sony NP-F550 battery formed a breakthrough in industrial production shows that China has Salt Lake with independent intellectual property rights developed comprehensive utilization of resources based on comprehensive development of salt lake resources, access to large-scale production of lithium and magnesium in a new phase.

Third, the domestic lithium production of business analysis

1. CITIC Guoan (000,839):

Qinghai CITIC Guoan currently holds 99.375% stake in national security. Qinghai National Security was established in 2003, mainly engaged in Qinghai Salt Lake, West taijnar lithium, potassium, boron, magnesium and other resources of the comprehensive development. West taijnar Salt Lake Qaidam Basin is located in the middle of an area of 570 square kilometers, the liquid resources to reserves of 3.08 million tons of lithium chloride, potassium chloride 26.56 million tons, 1.63 million tons of boron oxide, Sony NP-QM91 battery magnesium chloride 185.97 million tons. Calculated according to the design capacity, these resources available to the company for at least 25 years of mining, the potential economic value of 170 billion yuan.

CITIC Guoan is now actively seek dong taijnar and a right to exploit salt Li Ping. It is reported that a total investment of Qinghai Guoan 2.294 billion yuan, design production capacity of 30,000 tons annual output of lithium carbonate, 1 million tons of magnesium potassium sulfate fertilizer, 75,000 tons boric acid. If this goal can be successfully achieved, CITIC Guoan will become the world's second largest and the biggest producer of lithium carbonate.

However, instability in production processes, equipment, frequent maintenance, the whole of 2007, CITIC Guoan is only produced about 1,800 tons of lithium carbonate. According to reports, at present, CITIC Guoan Lithium Carbonate have four production lines had started only two, and has been at the side of the production side of debugging state. Actual output in 2008 is expected in 2000 tons, the progress of the comprehensive development of salt lake resources, the overall lower than expected. CITIC Guoan secretaries to directorate also said that at present there is no reason to achieve the design capacity, mainly in the company is still looking for more economical and reasonable mode of production. If you do not take into account the economics of production, the company an Sony NP-QM90 battery annual output of 10,000 tons of lithium carbonate production can be achieved. CITIC Guoan is now facing major technological and economic dimensions, namely, how the economic mode of production and realize the comprehensive utilization of salt lake resources.

CITIC Guoan production of lithium carbonate used calcination separation: The main advantage is the ability to separate high-Mg-Li ratio of brine ingredients, a large number of problems in dilute hydrochloric acid by-product recovery, the manufacturing process produces acid mist pollution, excess hydrochloric acid can not be processed, while pre - treatment as part of boric acid consumed entirely in handling difficult. At the same time produced a large number of calcined magnesia slag, due to magnesium slag containing boron, magnesium and boron separation is very difficult, calcined magnesium produced by the utilization of resources also need to be studied. Calcined acidic environment brick furnace equipment corrosion problems difficult to solve.

2. Tibet Mining (000,762):

CITIC Guoan holds a lithium-magnesium associated minerals, Sony NP-FM71 battery the past two or three years has not been a breakthrough in technology, mining in Tibet dominant position in the upstream raw materials is quite highlights. The company now has lithium reserves in first in the country, the world's third largest mining rights Zabuye Salt Lake for 20 years. This is the world's only exists in the form of lithium carbonate in natural salt lakes, in addition to the natural bottom of the lake shore as well as the deposition of lithium carbonate, the water content of lithium carbonate in a conservative estimate as high as 200 million tons. The Mg-Li ratio was only 0.02, the anomaly from a high proportion of Mg-Li Lithium brine problems, so in the future benefit from the mining of Tibet has great potential.

Tibet Mineral Salt Lake Zabuye concentration method using solar pond: Zabuye Salt Lake as a natural carbonate, magnesium and lithium than the lowest in the world, resources and excellent technique more reliable. But Zabuye - silver has more than 2000 kilometers, transport distance is too long, but the circuit does not pass Zabuye water, infrastructure and poor capacity to upgrade require significant capital investment. However, in terms of resource endowments, the most potential for future Zabuye lithium carbonate origin. In 2009 the company plans to produce potassium sulfate and potassium chloride magnesium fertilizer 15 each million tons of lithium carbonate by about 3,000 tons, plans to achieve sales revenues of 750 million yuan. The future by increasing the brine mining Sony NP-QM51 battery wells, and then increase the potassium chloride production capacity 120,000 tons, plans by 2010.

3. Western Mining Group

Qinghai Western Mining Group currently controls 74% of the shares lithium industry. Qinghai Lithium Co., Ltd is currently in the East taijnar to meet the capital of Qinghai Salt Lake extracting lithium and utilization of resources industrialization demonstration projects. In October 2007, Western Mining Corporation design capacity of 3,000 tons of lithium carbonate project started for production purposes. After a year of operation and production process transformation and optimization, to September 2008 reached capacity lithium carbonate on the project to achieve, to the current production of lithium carbonate products for more than 1,000 tons, more than 99.5% product quality and achieve low-cost, non - high temperatures and corrosion, no gas, Sony NP-QM70 battery no residue cleaner emissions from large-scale production.

Qinghai Lithium Co. membrane: its process route is to use multi-stage membrane separation technology, the old brine in the Mg: Li ratio from 20:1 to 1:2 or so, followed by adding sodium carbonate makes the lithium carbonate precipitation. At present the main problem is that in the reverse osmosis concentration process, the dense phase of the precipitation of some salt-poor control, easy to plug or damage to the film, the need to further expand the scope of operational parameters, stable process conditions. In 2009 are planned to reach about 2000 tons the amount of future stable expanded to 7,000 tons / year. Western Mining Corporation is currently under construction production capacity up to 2 million tons of lithium carbonate production base, to build more than 100 tons of high purity lithium Sony NP-FM50 battery carbonate projects and thousands of tons of lithium hydroxide on the project.

It should be noted that the Qinghai Lithium lithium carbonate industry, business belongs to the Western Mining Group and Western Mining, Inc. (601,168) only under the Western Mining Group, a subsidiary, however, Western Mining Holdings Qinghai Lithium Co., so that Western Mining there is the expected capital injection.

4. Salt Lake Group (000,578):

In order to comprehensive utilization of salt lake magnesium, lithium and other resources, "Eleventh Five-Year" period into Salt Lake Industry Group will invest an annual output of 100,000 tons anhydrous magnesium chloride, 10,000 tons lithium carbonate and so on, to build modern high-tech base in the salt industry. Salt Lake Group, a subsidiary of LandTek lithium industry, its processes, including resin adsorption, elution, concentration, membrane separation and carbonization process. Years ago, installed in the front part of the debugging resin adsorption. Lithium concentrations were lower due to brine a large number of brine to enter the resin bed, resin adsorption main problem is water consumption, resin consumption and power consumption, large, and because a substantial change in resin temperature adaptation is not enough, resulting in resin, are also addressing issues such as broken in. It is estimated that the average production of 1 ton lithium carbonate need to consume around 600 tons of fresh water, the average consumption level of renewable pH of about 5% of resin consumption is about 5% each. The cost of production the need for further observation, Sony Camcorder Battery expects its costs will be 1.5 tons million yuan.

Fourth, development of the industry outlook for lithium carbonate

From the development trend, new energy cars is undoubtedly the future direction of automotive development, while the lithium battery powered electric vehicles is the best choice. The future market for lithium batteries and battery raw materials, demand is enormous. For this reason, lithium carbonate, once mining extraction technology is a breakthrough, cost-effective reduction to achieve large-scale industrial production, the outlook for the future will be very broad.

According to the Investment Advisor "issued by China's new energy vehicles 2008-2010 Industry Analysis and Investment Consulting Report" points out that by 2012, China had 10% of the new production of the cars are energy-saving and new energy vehicles, according to an annual output of cars will be cars for the 10 million counted, China's new energy vehicles to reach an annual output of 1 million scale. Each new motor vehicle is expected to need about 0.08 tons of lithium carbonate, lithium batteries once the driving force large-scale application Camcorder Battery of new energy vehicles, the lithium carbonate market potential will be very huge, new energy sources is expected to only 2012 cars on the annual demand for lithium carbonate will reach 5 million tons.

The current domestic price of industrial-grade lithium carbonate to 45,000 yuan / ton or so, battery grade lithium carbonate price of 70,000 yuan / ton or so, high purity lithium carbonate price is as high as 100,000 yuan / ton or more, domestic involved in new projects because it is extracted using salt brine lithium carbonate, production costs in the 10000-15000 yuan / tons. Therefore, the market generally felt that the profitability of lithium carbonate products is very high, will give investors Camcorder Battery a huge increase.

Bolivia's lithium resources of transnational corporations covet

Bolivia's lithium resources of transnational corporations covet

Standing on the world's largest salt Beach - South America Bolivia uyuni salt marsh Laptop Battery (Salar de Uyuni) the center of your mind the first word that emerges is "empty." Everywhere you can see, there is no bush, mountains and valleys, there are only endless white.

This piece of salt in the hinterland of South America and the exotic deserted beach, it might be Mother Nature on the "open" the best word annotations. From the Inca period (2000 BC) until today, there has been rarely visited, but the changes may soon occur. Here excavation, you will find brine - infiltration of salt water, rich in the world's lightest lithium.

19th century, the invention of pneumatic tires to make rubber worth doubled; today, as the world's passion for green energy in a wave after wave, lithium may also be so expensive. Over the years, lithium has only been a small amount of land used in notebook computers and send and receive e-mail the "BlackBerry", but in the future it will be widely used in manufacture of electric car batteries.

Environmentalists, manufacturers and national governments have indicated that electric cars will replace gasoline and diesel-powered means of transport. JVC BN-V107 battery This Bolivia is good news, the country has a lithium reserves of 5.4 million tons, accounting for half of the world's reserves.

Bolivian Minister of Mines and Metallurgy Airy Cha Su Luis Alberto (Luis Alberto Echazú), said: "Lithium is very important for us and the world. We hope that next year's 1,200 tons of lithium extraction, this is only the beginning. After entering the right track, we will be production increased by 10 to 15 times more. "

Uyuni salt beach has four drilling. In addition, the edge of the beach is located in Salt JVC Camcorder Battery Village (Rio Grande) is also building a state-owned pilot plant.

But the mining work was not smooth sailing. British "Guardian" reported that the Government of Bolivia in other areas often conflict with the foreign multinational companies, and has not reached a contract. Some people think that may never be no agreement is reached, because investors need a lot of lithium extraction.

Cambridge Energy Research Associates and the consultant a former energy minister Carlos Alberto Lopez (Carlos Alberto López) said: "The Bolivian Government has often confiscated assets, tore up the contract, so foreign companies dealing with fear. Bolivia's ideology and commercial difficult to reconcile the realities of the world. For the commercial value of lithium can developed in the short term, I doubt it. "

Pessimists fear that the "double defeat" situation: the lack of motor vehicle dealers are required to the battery electric vehicles, while Bolivia, as the world's poorest countries, but also lost an opportunity to develop.

Once the camel pastoralists and trade union leaders, Bolivian President Evo Morales (Evo Morales), concerned the Western multinationals JVC Camcorder Battery will drain the wealth of uyuni salt, lithium development is a test he faces. Morales said: "The Bolivian government will not allow others to control this natural resource." But he also acknowledged the need for a foreign partner.

Government of Bolivia is working with France Bolor companies (Bollore Group), South Korea's LG Corporation, Japan's Sumitomo Group (Sumitomo) and the Mitsubishi Group (Mitsubishi) negotiations.

Government of Bolivia said it will choose one to help Bolivia's mining industry, not only for the purpose of the company. Bolivia plans after mining, processing and value-added services, such as in its domestic manufacturing lithium batteries or electricity board.

6 multi-million dollar investment in plant is the first step Sony NP-FS20 battery village. 48-year-old site command Marcello Castro (Marcelo Castro) said: "We started from scratch. This is a historic moment, we are fighting for ourselves. The developed countries can no longer plunder the resources of Bolivia, which is a new law." skeptics think he was delusional. Slow progress of the pilot plant, and not the results of the negotiations of transnational corporations, but also there was no work schedule.

British "Guardian", said Bolivia in 2006 the nationalization of the oil and gas industry led to shrinking of foreign capital, the output decline in state-owned energy company YPFB into a quagmire of corruption.

Lopez said: "Bolivia's credit doubtful. I think that investors will not put their heads smashed to go out."

"Guardian" is expected to be the arrival in 2015 of lithium shortages Bolivia prevail. Bolivian workers organizations uyuni (Uyuni) the leaders of Bari Luokeleke Sony NP-FS10 battery (Paulino Colque), said: "We used to have unpleasant experiences. Investors can come, but it must act as partners, rather than the sponsor."

Japanese car battery to weave and usher in the Warring States Period

At present, the global Li-ion battery has become white-hot competition in the market, Laptop Battery the market becoming saturated, growth slowed. Meanwhile, with the energy and environmental pressures continue to increase, new energy electric cars become louder and louder, national government policy support of electric vehicles has also increased, from the development trend, new energy vehicles is undoubtedly the future of automotive development direction, while the car battery is a new energy vehicles, one of the core components.

At present, with the maturity of automotive lithium battery technology and lower prices, more and more consumers began to look toward electric vehicles, while manufacturers are also moving to bring the new energy future sales of electric vehicles as a priority. At present, more and more car manufacturers to choose from lithium batteries as a new energy car battery power. At present many well-known car manufacturers are working to develop a lithium-ion power battery electric vehicles such as Ford, Chrysler, Toyota, Mitsubishi, Nissan, Hyundai, France, Courreges, Ventury so.

Li-ion battery is behind the hot car prices on the plug-in hybrids (also known as plug-in hybrid electric vehicles) and pure electric vehicle market prospects of the recognition and R & D capabilities of their current concerns. While the Bosch stand out by the end of 2008, said to be electric cars on the heat to keep sober, but even cool, such as Bosch, has also set up JVC GR-DX300 battery a joint venture with Samsung plans to achieve volume production and sales in 2011.

Japanese cars lithium battery industry appears to weave the pattern of

Warring States period, Qi, Chu, Yan, Han, Zhao, Wei, Qin Qi-Xiong side by side. The mid-Warring States period, Qi, Qin the most powerful between the two countries, East-West confrontation, competing for allies in an attempt to beat each other. The other five countries to be outdone, and Qi, Qin and sometimes confrontation between the two countries, sometimes jointly. Intensified conflict between major powers, diplomatic activities have become more frequent, there have been combined vertical and horizontal struggle.

Automotive Li-ion battery industry because of tremendous value inherent potential of electric vehicles, battery materials upstream suppliers and downstream manufacturers of automotive lithium batteries for automotive operations have been tiptoeing around a long time. Now, Japan's electric car on the middle and lower reaches of their respective constituents for the purpose of the emergence of joint ventures or mutual competition for automotive lithium-battery business phenomenon, its pattern and the Warring States period to weave JVC GR-DX45 battery strategy very similar.

Such as Fuji Heavy Industries, and NEC to develop low-cost monomer (Cell) Manganese lithium-ion battery (ie, lithium manganese batteries); Following GS Yuasa Yuasa batteries separately with Mitsubishi (Mitsubishi), Honda co-developing automotive lithium battery technology development, sell manufacturing and distribution businesses. Toyota (Toyota) on the Panasonic EV Energy funded from 40% to 60%, be included in a subsidiary; Enax Germany Degussa and Japan respectively to 50% in China, funded the establishment of Degussa Enax (Anqiu) Power Lion Technology Inc., producing lithium-ion battery electrode and sales, the plant also produces lithium-ion batteries for electric vehicles electrode, and supplies to China, Europe and the United States Japan and other countries.

Japanese car company the world's top-ranking lithium batteries

According to Deutsche Bank research shows that vehicle the following JVC GR-DX37 battery 10 companies most willing to work with companies to develop automotive lithium battery: 1) Johnson Controls-Saft (the United States and France, Johnson Controls and Saft joint venture); 2) A123 Systems, Inc. (from the Massachusetts Institute of Technology College, General Electric and other investors to set up the company's group of co-operation with the mainland); 3) LG Chemical (the company's U.S. subsidiary Compact Power); 4) EnerDel (Ener1 and Delphi joint venture); 5) AESC ( Nissan and NEC joint venture); 6) PEVE (a joint venture between Toyota and Matsushita); 7) GS Yuasa; 8) Hitachi; 9) Sanyo Electric; 10) Samsung.

Alternative energy sources and authoritative website Green Car Congress editor Michael Millikin predict the future, vehicle manufacturers of lithium batteries the "big three" are: 1) PEVE, 2) AESC, 3) LG Chemical. Most of these suppliers have contracted with at least two vehicle companies, while the world's major automobile companies are usually several options for at least two lithium battery supplier.

From the above study can be found, at present, the Japanese lithium battery suppliers in the global market indeed account for a large JVC GR-DX35K battery advantage.

Lithium-iron battery has become the domestic and Europe and the United States over the next decade the most important electric cars lithium battery materials

Lithium-iron battery has become the domestic and Europe and the United States Laptop Battery over the next decade the most important electric cars lithium battery materials, batteries at the current exhibition in China, in addition to the original familiar BYD, Suzhou Star Constant power supply makers to participate, another fu from the United States San Jia Li-ion battery AABC car show to return to Taiwan, Li-Kai (Aleees) Among this year's venue, but also close attention.

Early in June, Taiwan's Li-Kai power and the Taiwan Synchrotron Radiation Research Center (NSRRC) ran off in the U.S. automotive lithium exhibition, published a new lithium iron phosphate cathode material for a total of olivine crystals: LFP-NCO (Nano-Co-crystalline Olivine), LiFePO4 · zMO (MO = metal oxide) by the end of June, but also prompt return of the San Jia in Beijing at the China Battery Exhibition, in addition to the material properties of a new recognition of the trade, in addition, a more eye-catching show with the huge scale of and educate the public of the important energy-saving emission reduction.

In an interview with Beijing TV interview, Aleees marketing department spokesman for the Su Xiu Xiu mentioned that, in countries around the world have invested heavily in R & D announced that electric car, while living in the key face of the cathode material patents and product features fierce competition, Aleees the development of lithium iron phosphate crystal material has a total cost advantage, a good consistency and a high-performance capacitance play, cost-effective even beyond the industry's expectations for the lithium battery power by domestic and foreign manufacturers panasonic CGR-D08 battery with a high degree of attention and a substantial increase the impetus for the performance of lithium batteries, for environmental protection and energy saving industry, provide a new solution.

At the same time in the past two years, Aleees actively involved in the cause of the domestic ranks of electric cars, and electric car industry has made tremendous contributions to:

1.nbspnbspnbspnbspnbsp Aleees in the country provides the world's most cost-effective lithium-iron material with excellent quality at the same time significantly enhanced the yield lithium battery electric vehicles, an increase of 40% of the profits of the downstream customers.

2.nbspnbspnbspnbspnbsp Aleees the price of lithium iron battery materials, compare United States and Europe reduced 60%, Aleees practical action in support of the cause of the domestic electric vehicles. To reduce dependence on oil and thus enhance China's energy security.

3.nbspnbspnbspnbspnbsp Aleees through the company's co-operation with domestic battery, making the price of lithium-iron battery, comparing European and American countries at the same level battery factory, reducing by 60% of the cost, an increase of 25% of the lithium battery Laptop Battery capacity, all the lithium-iron battery indicator Japan and South Korea all of Europe and the United States are the leading manufacturers, greatly elevated China's battery in the international competitiveness.

Also at the show among the academia and the industry in the lithium batteries at home and abroad are renowned researcher Dr. Huang Xuejie Chinese Academy of Sciences, said that with the coming oil shortage, in the past in order to dominate the internal combustion engine for the automotive industry, will soon become dominated by the Li-ion rechargeable battery industries will be the era of electric vehicles, while China will surpass Japan to become even more is the world's largest Li-ion battery manufacturing center Dr. Huang Xuejie look forward to having more and more companies such as Aleees right along this path, continue with a more number of partners together to enhance the industry's core competitiveness.

Taiwan Power Technology Co., Ltd. Li-Kai (Aleees), participated in the 2009 Long Beach, California in the United States of Advaned Automotive Battery and EC Capacitor Conference (hereinafter referred to as AABC) exhibition, from June 8 to June 12 for five days display, and with Exxon Mobil, Hitachi, A123, Toyota, Honda, SK energy, LG chemical and the U.S. Department of Energy the same as the main sponsor, which Aleees also held in the June 11 lunch lectures, to Asia, Europe and the United States people that lithium batteries for electric vehicles and energy-saving industry, the contribution of emission reduction, access to a warm response from all walks of life, during which a number of car dealers and battery manufacturers to produce materials for Aleees a high degree of interest and inquiry.

At the same time, Aleees also invited Taiwan Synchrotron Radiation Research Center (NSRRC) Dr. Wu for Aleees the development of a new lithium panasonic NV-DS30 battery iron phosphate (Lithium iron phosphate, LFP) Cathode Materials: LFP-NCO (Nano-Co-crystalline Olivine), LiFePO4 · zMO (MO = metal oxide) for lithium-ion battery of new technologies for the industry to profile. X-ray diffraction analysis (X ray diffraction), electron microscopy (scanning electron microscope, SEM), SEM / EDS (Scanning Electron Microscope with Energy Dispersive Spectrometer), transmission electron microscopy (Transmission electron microscopy, TEM) analysis, extended X-ray crystal X-ray Absorption Fine Structure Analysis (Extended X-ray absorption for fine structure, EXAFS) and other high-precision equipment analysis, confirm the properties of the materials and differentiation. From the TEM analysis on all the metal oxides are uniformly dispersed in the particles which shows that non-by-coated metal oxides or three exist in the form of mixed particles, but rather exists in the way of crystallization.

This technology developed by LFP-NCO materials can significantly improve the traditional lithium iron phosphate material with low conductivity, impurities and more problems, and provide customers with cost-effective products. The participants for a new lithium iron phosphate material are extremely excited about the new development, so that the application of battery power to produce excellent performance.

LFP-NCO of the particle size distribution is very uniform,panasonic PV-BP17 battery D50 particle size of 6 microns, D95 particle size of 10 microns or less and characterization of a single peak, another from the electron microscope, all the particle size of the particles show a good consistency. The physical characteristics of a stable battery manufacturers to provide a stable production and decrease in cost, reduction of defect generation. G generated by the same time, the capacitance characteristics of good, button batteries 0.1C discharge, the Croatian electric capacity to play up to 155 mA h / g, while the capacitance is to play up to 0.2C g 130 mA h / g, so that power batteries to play the electric capacity of the battery beyond the current industry expectations.

From the industry point of view, Aleees considered relevant by the industry must solve the vehicle battery to poor quality, high price of the issue, including China, the entire industry and can not be fully expect the taxpayers to subsidize to solve, but rather should be Li-ion battery co-operation of upstream and downstream firms to be overcome.

Aleees that the current industry-accepted by the battery for the price that consumers can not get the attention it deserves, panasonic VW-VBD210 battery a PHEV40 price of lithium batteries two trillion U.S. dollars, consumer enthusiasm for environmental protection will be high prices dampen the battery. Aleees that within two years, Asia's automotive lithium battery manufacturers can generally reach USD1 / Ah objectives, such price changes can make PHEV40 lower prices for consumers to purchase more than 50% this way with the Government 10 City 1000 plan, can effectively accelerate the expansion of Li-ion battery applications in the Chinese market, making electric car industry in the Chinese market to bear fruit.

From a technical point of view, Aleees that although the LFP has been generally regarded as a vehicle lithium battery safety issues and pricing issues, one of the analytical process, but due to the prevalence of LFP upstream materials over the past two-valent iron is difficult to control, as well as electrical conductivity due to good question, making lithium-ion batteries manufactured by manufacturers of lithium batteries, mostly there is not as good as the expected yield and capacity problems in such a question also makes the LFP battery price has not yet reached USD1 / Ah technical key Aleees believe that China has a number of home Doping by the way vendors have successfully solved the problem of a poor electrical conductivity, but still there are two panasonic CGA-DU21 battery hidden ferrous beyond our control, so that makes the potential problem of price and quality lithium batteries are still disturbing.

At the same time the face of strong foreign competition and commercial interference with the patent means, making China the world's lithium batteries into the door is not easy questions. LFP materials as the sole representative of the Asian manufacturers Sanjia AABC's Aleees that this issue still have to work together to solve the world's manufacturers, over the past fourteen years, LFP due to the existence of the patent monopoly, hindered the development of LFP at the moment the patent The issue of monopoly no longer exists, the Chinese manufacturers should take advantage of this opportunity to strengthen cooperation and exchanges, co-operation as soon as possible so that the battery manufacturers have a stable quality, panasonic CGA-DU14 battery affordable LFP upstream materials, allowing electric vehicles to expeditiously complete the Sheung ideal.

BAK Chief Engineer MAO Huan-Yu: Power battery design can not be a tightrope

Industrial design is sometimes invisible to the user, but in fact the design of stealth may be more important,Laptop Battery these and related exterior products designed to make access to security, functionality and cost advantages.

The world's largest manufacturers of lithium-ion battery, one of China BAK Battery Inc. chief engineer of MAO Huan-yu, it is reasonably designed to allow BAK Battery across from the production of mobile phone batteries to laptop batteries threshold. BAK Battery Li-ion laptop batteries fully automated production line in 2006 with mass production, which is China's first notebook battery production lines. Previously, in addition to Samsung, LG occupies a small share of the two Korean companies, the notebook battery market was almost Japanese Sony, Sanyo, Matsushita three Japanese companies a monopoly.

In January of this year, BAK Battery electric vehicle battery power projects have been included in the national 863 electric cars special. BAK Tianjin is currently sony NP-F10 battery under planning and construction of a "motive power industrial park", targeted to be completed within this year, an annual output of 30 million lithium-ion battery production line to form a sales volume of about 500 million U.S. dollars. By then, the industrial park as the country's largest and most advanced technological level of the lithium-ion battery production base to meet power tools, electric vehicle battery market demand for development.

58-year-old Canadian of Chinese MAO Huan-yu, 1990, Memorial University of Newfoundland in Canada electrochemical doctorate in 1996 employed in the Chinese electronics [0.73 0.00%] Part 18 leading high-energy lithium-ion batteries developed in 1999 by the State Council confers on foreign experts in China highest honor award "Friendship Award" by The People's Republic of China in 2001 International Scientific and Technological Cooperation Award in 2004, joined BAK Battery.

"Business Week": BAK notebook battery production scale has grown from 2 million per month increase to 8 million, successfully cut into the global notebook battery market. In recent years, the battery explosion took place so that the outside world for the safety of lithium batteries has been sony NP-FE1 battery questioned, how you design the product at the same time ensure the safety and competitiveness?

MAO Huan-yu: The safety of lithium batteries is a very complex issue. From the raw materials involved in research and development, selection, to the battery design and production process, and so all the links.

Optimal design of these batteries is very important. Simply put, performance and consistency of less demanding battery of good quality control, it's like walking on a flat road is not easy to wrestling. However, if the battery pack to improve the consistency, improve performance, design manufacturing sector as demand balance beam walk, and to be very very careful. If all aspects of the battery indicators are promoted to the limit, then your design is tantamount to asking a tightrope manufacturing sector, could fall at any time to go, but also to the production process pressure is also very large, we have an annual output of several tens of millions of batteries to ensure the quality of each piece of the battery no problem, it is a very big challenge. This requires us to find the performance by optimizing the design and quality balance.

"Business Week": the battery in the notebook industry chain to withstand a lot of pressure, thin and light machine manufacturers, mobile technology requires sony DSC-T7 battery the sustained pursuit of battery design with high-wire act.

MAO Huan-yu: Indeed, the thin and light notebook PCs, mobile-based battery design and manufacture of higher and higher demands, enabling the design parameters have to push the limits, which require us to continuously optimize the design, continuous improvement, generation product generation, product enhancements, in the process of gradual accumulation of experience.

"Business Week": Three years ago, BAK coincided with Sony laptop battery production companies in the industry experience "battery door," was designed to have a kind of special consideration?

MAO Huan-yu: laptop battery explosions are generally caused by overheating due to internal short-circuit or overcharge caused by a result of this return to their roots in the battery development and design, there is no better protection of the design. We each have adopted a triple laptop battery protection, namely over-current protection, over-voltage protection, internal pressure is too large to protect, that laptop battery current, voltage, the internal pressure of any kind of extraordinary circumstances, Casio Digital Camera Battery the laptop battery will be automatic protection, would not have exploded and other undesirable phenomena. Before the commissioning of BAK specially set up a safety committee for each link in the chain to design review, after repeated experiments testing a variety of security until the safe, reliable, automated production line was carried out into manufacturing.

Manufacturing is also very important in 2006, the battery explosion problem lies in the production chain. In fact, after Japan, Korea and other major battery manufacturer in the production of the early days, there have been product safety issues, but at present we have produced tens of millions of batteries, since there has not been first introduced the same kinds of accidents. An argument with our clients, this is a miracle.

"Business Week": how did you do it?

MAO Huan-Yu: From mobile phones to laptop battery production, the cross key is to ensure the consistency of the battery. Previously the majority of our business has been producing lithium battery cell phone batteries, while the mobile phone battery is a single use, lower the requirements for consistency, so the production of mobile phone batteries, Chinese enterprises by hand instead of expensive equipment to obtain a cost advantage.

But the laptop battery is not the same. With the different mobile phone battery, laptop battery usually 6 or 8 batteries series-parallel use of the nikon CR-V3 battery consistency requirements are higher, if there was a bad performance, then performance of the entire battery pack down. Certainly not with the manual production to ensure consistency, so we can see that apart from BAK Battery addition, there are no other businesses truly realize the amount of laptop battery production, to be the world's largest PC company recognition into their supply chain.

"Business Week": BAK announced earlier this year into the electric vehicle battery power industry, the difficulty of this crossing is greater than the last time from the cell phone batteries to laptop batteries, right?

MAO Huan-Yu: Of course, a laptop battery is usually six or eight a combination of batteries and power cells are hundreds or even thousands of blocks of series-parallel block the use of higher demands for consistency.

Simply put, this cross is a good design coupled with a good production. Even if the world's best design, manufacturing processes do not increase, no matter how good design can achieve, both of which are very important. We make a first-rate Chinese enterprises to truly satisfy the use of electric casio CRV3 battery vehicle batteries, one should technology do the second is to create well, are indispensable.

The question now is, notebook battery, when we enter this industry already have a standard product design, followed by Sony's basic model can be done, and the focus is to improve performance. But the electric car battery now the shape of the product do not know what is round the square, or a long flat, do not know. Before the laptop battery, we need to improve the manufacturing level, you can buy Japanese equipment, but the electric car is a new industry, and now we have to have a company pick the first designs to come up with such a standard, everyone recognized.

Eco-car will use lithium batteries

Tokyo, August 27 (Xinhua Green) Japan's Mitsubishi Heavy Industries Ltd., 26, announced its entry into lithium-ion battery market. Compaq Evo N115 battery The company plans to fall in 2010 before the Nagasaki Shipyard to build pilot plant, production and application of Mitsubishi Heavy Industries of forklift batteries and used on a medium-sized wind power generation equipment, power reserve in a large battery. The project is expected investment of about 100 billion yen (about 725 million yuan).

Japanese manufacturing generally optimistic about the potential of large lithium batteries, lithium batteries are being vigorously developed in the power, automobile and other fields of applied technology and sales market. Mitsubishi Heavy Industries Ltd. and Kyushu Electric Power companies will jointly develop lithium-ion batteries as the power companies for emergency power supply with the power and the possibility of outlying islands.

Japan's Toyota Motor Corporation in mid-August has been basically decided to purchase hybrid Sanyo lithium batteries used in cars. This lithium battery with the Prius and other models equipped with Ni-MH battery is more superior compared to the performance. Toyota and has been evaluated and that "high-tech." Toyota will Sanyo lithium batteries are used in 2011 on the sale of hybrid sport utility vehicle. Per year is expected to start procurement of 10000 vehicles used in batteries, in the future may also be used by the family charging power supply plug-in hybrids Acer BATCL32 battery and electric vehicles.

The popularity of lithium and mineral resources

Buenos Aires newspaper August 27 (Xinhua Chen Airlines) Bolivian Mining Minister Luis Albert Thoet Cha Su-25, said that, although there is Brazil, South Korea and other countries with the Government of Bolivia signed a letter of intent However, the Bolivian government has not yet signed with any country develop lithium ore formal agreement.

Echazu reason why there is such a position because Bolivian President Evo Morales and Brazilian President Lula on the 22nd of this month signed a memorandum of understanding referred to in Brazil will invest in Bolivia's lithium resources, and help train Bolivia IT staff. This has led to speculation that the two countries have reached a development of lithium-industry strategic cooperation agreements.

A few years ago, geologists located in southwestern Bolivia, beach exploration uyuni salt out of a lithium-rich mineral reserves. In this piece of 12,000 square kilometers of salt beach, the proven reserves of lithium up to 550 million tons, accounting for more than half of the world's total reserves. The case of lithium-rich mineral resources and immediately attracted the eyes of the world's Acer BATCL32L battery large enterprises.

Japan's Mitsubishi, Sumitomo, South Korea LG, French industrial giant Bolloré and other auto batteries have contact with the Bolivian government, expressed its willingness to develop and purchase lithium resources. In April of this year, Morales met with France's Bollore, when company representatives also expressed willingness to develop with foreign. Morales said that, not only for the development of green energy is of strategic significance, but also for Bolivia's economic growth has brought new opportunities.

Bolivian government officials have recently stressed that Bolivia can become a green energy center in South America. Foreign investment in mining and mineral resources in the process of lithium is not simply engaged in mining, but through the development of lithium ore processing industry to promote the rapid development of long-term planning, through the deep processing of mineral resources in the development of high value-added industries, especially the introduction of international advanced technology.Acer Aspire 2000 battery Bolivia's foreign partners in the choice to request their ability not only to have the mining, but also should have advanced processing technology and comprehensive development capability.

At present, the Bolivian government has made a specific investment plans, the initial development funds invested 6 million U.S. dollars, in the salt beach wells and the construction of processing plants in the surrounding area. Followed by a total of 200 million U.S. dollars will also be an additional investment. According to official forecasts, in 2010 uyuni lithium mining output is expected to reach 1,200 tons, but to be fully operational, the more increase to 1.8 million tons.

Morales said that the Bolivian government will not give up the right of the state management of natural resources. Bolivia's lithium mining for the development of its own principles, is to produce lithium batteries in Bolivia as well as other lithium products, in order to comprehensively promote the industrial development of Bolivia. Roch, Deputy Minister of Science and Technology-Balkaria Carvajal recently said, "In recent years, the world's industrial sector there is a clear consensus that the strategic direction of energy should be polluting energy sources to clean energy transition. Lithium helps to ecological and environmental protection The important component of clean energy. "

"Moving the world forward element"

Beijing, August 27 (Xinhua Zhang Lei, cattle Reflexite) In recent years, new energy vehicles heats up, the application of lithium batteries Acer Aspire 2016 battery is also extended to pure electric vehicles, hybrid vehicles, fuel cell vehicles and other new energy vehicles. In a variety of lithium batteries, lithium iron phosphate batteries for its excellent performance as a new energy vehicles of choice for battery power.

At present, governments have steadily increased its lithium battery electric car R & D investment. Recently, the U.S. launched a 2.4 billion U.S. dollars in electric car project, of which more than half of the funds will be used for battery manufacturing projects. In addition, various research and development of new lithium-ion battery is also in full swing in progress.

This year, the Massachusetts Institute of Technology researchers have invented a charging material surface processing technology. The introduction of new technology, lithium-ion battery can be charged within a few seconds. Since this new technology is the basis of existing lithium-ion battery improvements, no new material, so after two years there will be a commercial product launches.

Germany's Daimler has announced that in mid-November 2009 will be manufactured at the plant in Hambach, France the second-generation "Smart" electric vehicle (EV). The new EV will be equipped with the U.S. Tesla Motors to provide lithium-ion rechargeable battery. Lithium-ion rechargeable battery has a capacity of 14kWh, the use of 220V power charging, 3 hours will be fully charged. Continuous driving range of up to 115km, enough to meet the average daily driving distance of 30-40km of the city usage requirements. Acer Aspire 2200 battery The vehicle planned for 2012 batch on the market.

Lithium is the world's lightest metallic element, lithium-resources development and utilization of more and more subject to national attention. 1817 study in Sweden Aerfuwei des Houtaux Island penetrating lithium feldspar found in lithium, and the element name in Greek.

Automotive Safety and Energy, Tsinghua University State Key Laboratory assistant researcher Xu Liang Fei said that the 20th century, the early 70s, lithium batteries used first for military purposes. With the development of microelectronics technology, lithium batteries appeared at every aspect of daily life, such as cardiac pacemakers, notebook computers, digital cameras, mobile phones and so on.

The United States is the world's largest producer of lithium products, and consumer, is also the largest exporter. Japan is the world's largest importer. Lithium products in the world's total trade volume early in this century has been more than 500 million U.S. dollars.

Non-ferrous Metal Research Institute, deputy director of Xinjiang, China Ma Yu-hsin, lithium metal, lithium alloys and its compounds for its excellent features, not only in atomic energy, aerospace and defense sophisticated industrial use, but also in metallurgy, electronics, glass, ceramics, oil and chemicals, batteries, rubber, steel, machinery and medical and other high-tech fields and the field of traditional industries, gaining a wide range of applications. It had been included in a "strategic metal" has also been rated as theAcer BATBL50L6 battery "energy metal", "moving the world forward elements" and so on. Some scholars even believe that the 20th century was the century of steel and oil, while the 21st century will be electronic and lithium-century.

Toyota to develop lithium batteries can significantly increase the storage capacity of new technologies

U.S. Automotive News China, "Tokyo - Toyota Motor Corporation has developed a can significantly Compaq EVO N100 battery improve the storage capacity lithium-ion battery of new technologies, so as to develop a more practical electric cars provided an opportunity.

Toyota Motor Corp. spokesman Paul Nolasco said that this progress - the processing of single crystal lithium cobalt oxide - from Tohoku University in Japan on joint research.

This new technology toward a more adequate manufacturing capacity battery has taken a big step, but Nolasco declined to the possible increase in battery storage capacity, Compaq Evo N1020V battery or endurance mileage of electric vehicles for evaluation.

Japan's "Nikkei Business Daily" reported that the technology will ultimately make lithium-ion batteries can store 10 times its current capacity of similar cells. The newspaper said that this progress can be roughly 10 times the mileage increase. A higher storage capacity also enables the Toyota Motor Corporation reduce the battery size, weight and possible costs.

Lithium-ion batteries are seen as the key to mass marketing electric vehicles because they are more than current hybrid vehicles use nickel-metal hydride batteries lighter, and more abundant electricity.

However, the Toyota Motor Corporation to a large extent still have to bypass the electric vehicles Compaq Evo N1000C battery on the grounds that modern lithium-ion battery power is still too weak to contain, not for the all-electric drive system to provide sufficient endurance mileage vehicles.

"The Nikkei Business Daily" reported that Toyota Motor Corporation is now using lithium-ion battery cathode usually with multi-crystalline form of lithium cobalt oxide-doped graphite particles produced.

However, the use of single-crystal form, the Toyota Motor Corporation to reduce the use of graphite, which also helps to produce lithium-ion current to create more storage space.

The newspaper reported that non-graphite cathode may have to spend another 10 years to develop, and then lithium-ion battery should be able to store 10 times Compaq Evo N115 battery the current capacity of similar cells.

On the competitive focus of new energy vehicles - Power Battery

As a new energy vehicles driven by the core power batteries are expected to rewrite the global car industry IBM ThinkPad 240 battery and parts patterns, a submarine buried in automobile plants, parts suppliers, electronics companies have been among the Running out of hair-trigger.

If we say that two years ago, the domestic prices of a car said, "the battery to change the world" is just wishful thinking lie, then just two years later, has rarely been doubts that.

Ye Hao hybrid and pure electric vehicles worth mentioning, as the new energy vehicle at this stage the most realistic solution, Tracing the source, the competitive focus of new energy vehicles fall on the core of their drivers - power batteries. It would appear that the battery described as the core driver to change the world, was not excessive.

For this reason, more and more car manufacturers will be the battery as to occupy the top priority of new energy vehicles Heights. Transnational corporations as well as some local manufacturers have been or are in the relationship between the battery as a top priority for the future to do business, or with e-business alliance, or joint development IBM ThinkPad 240Z battery between enterprises. Although the surface looks calm, but in fact, a submarine buried in the automobile factory, parts suppliers, electronics companies have been among the Running out of hair-trigger.

Reshape the global industrial structure

There is no doubt that the new business opportunities in front of those in power the battery has been based on research and development companies will emerge as a new round of energy industry beneficiaries. To industry estimates, it also may to a certain extent, change the pattern of the global automotive parts suppliers.

Judging from the current point of view, automobile factories and spare parts are mostly relying on the traditional e-business enterprises and even the cooperation of the joint development of car batteries. Auto parts enterprises, only Bosch, Continental, Magna, Johnson Controls and other areas in the lithium battery to maintain large-scale investment in most other production-ready automotive battery business, many were not in the ranks of auto parts, for the battery industry, which has great potential, but unfamiliar areas, car prices mostly through joint ventures or acquisitions to maintain industry IBM ThinkPad A30 battery contacts.

Jia Xinguang celebrities in the industry believe that the benefits of this is that individual enterprises will not only reduce the risk and cost, but also make those non-vehicle lithium battery companies, including Toshiba, Samsung SDI, LG Chemical, etc. have the opportunity to enter the auto parts supporting areas, Jia Xinguang told reporters: "These new entrants to the market prospects may be better than the traditional parts enterprises."

The fact is also generally confirmed this. According to Deutsche Bank research shows that most automobile companies are willing to develop lithium batteries car companies are: by the United States and France, Johnson Controls Saft joint venture set up by Janson Controls-Saft, from the Massachusetts Institute of Technology, GE Capital set up A123 Systems, Inc. by Nissan and NEC established AESC, set up by Toyota and Matsushita PEVE and the LG Group, LG Chemical, and other enterprises. IBM ThinkPad A31 battery One of the most promising by industry was PEVE, AESC, and LG Chemical. Forum

It is noteworthy that these enterprises or by vehicle business and e-business joint ventures, or branches of e-business, automobile companies, only Toyota, Honda, Daimler and other traditional methods of direct investment in the battery.

With the global automotive battery industry entered the period of rapid development, the battery manufacturers to engage in fierce battle for market competition, cross-industry alliances will become more common in automobile plants and parts suppliers also likely to show a new pattern of competition.

"Ni-MH," Re-thinking first

With the developed countries have gradually formed a cross-sector enterprises, the progress of technology alliances, domestic battery industry is still in the industry, the definition stage, in the process of industrialization seems to have been a step behind. To choose a future in the direction of battery technology, engineering department recently issued a letter of "new energy automobile manufacturing companies and product Access Management Code" has sparked much controversy.

In accordance with "rules" provides, according to different stages of development of new energy vehicles will be divided into initial stage IBM ThinkPad 600 battery where the development period, three stages of technology maturity. Among them, in order to lithium-ion battery powered hybrid and pure electric vehicles is a developmental period; the use of lead-acid batteries and nickel-metal hydride batteries in hybrids are classified as mature.

This is nothing wrong with different countries should be based on its own national conditions and make different choices for the underlying battery technology R & D and marketing to support the strategy. Controversy is that, "rules" to define product development period can only be approved by the regional sales use, and at least 20% of the product running in real-time monitoring of sales of mature products can be used across the country.

The industry is concerned, which to some extent will affect the pace of development in lithium battery cars, damage cars enterprise R & D, ultimately result in the development of new energy vehicles one-sided and unbalanced.

In fact, the impetus for new energy vehicles using lithium batteries IBM 02K7016 battery, or whether it is nickel-metal hydride batteries, even in a global context, the argument is a long time. Tsinghua University and expert Lam told reporters, including the Prius, there are now 99% of the world's hybrid cars are based on the nickel-metal hydride battery power, but even so, including Toyota, including the international mainstream automakers generally agreed that lithium -ion batteries will gradually replace the nickel-metal hydride batteries, a new energy future, the main driver of the car.

"Electric cars are the reason why not become developed, mainly subject to the battery. Therefore, the development is inseparable from the battery on this core technology," Jia Xinguang told reporters that "relatively nickel-metal hydride batteries, lithium battery performance is better, the current global electric vehicle batteries are mainly used lithium batteries, and our in lithium battery production but also has advantages. "

Lin Jian also said: "From the cost and commercial point of view, Ni-MH battery more realistic. In addition to the Prius other than the majority of domestic research and development of new energy vehicles being used is also a nickel-metal hydride batteries are already proven can be commercial, large-scale battery system. "If so, why the Ministry of Public launch of such a letter IBM ThinkPad G40 battery to invite criticism of the new energy vehicle development road map? An industry to a journalist to reveal some of the reason.

Choice of routes, in addition to the technical features of products, the key will depend on whether the conditions. At present in China's automotive battery production enterprises with a production capacity of nickel-hydrogen batteries accounted for the majority of companies, including Chunlan, the torch high-tech, Hunan Shenzhou batch of enterprises, private enterprises, as well as complete vehicle, including Chang-jie hun [synthesis Photo Forum] , Chery A5, FAW Pentium, GM LaCrosse [synthesis Photo Forum] and so on, most of the brands of hybrid cars are used in nickel-metal hydride batteries. The industry believes that the reason the first nickel-metal hydride and then lithium electricity, a state based on the status of the battery industry conditions and pragmatic considerations.

"At this stage the main push nickel hydrogen, lithium does not mean that in the future to give up power technology, in fact, nickel-metal hydride batteries and lithium batteries have their own different strengths in the future is entirely possible to achieve common development," deputy secretary IBM 08K8026 battery general of the National Federation by Choi Dong-tree said.

Toyota is an instance of the new energy routes. Toyota's hybrid (HEV) in all of the use of nickel-hydrogen batteries, while the plug-in hybrid (PHEV) is using lithium-ion battery. In the technical line of choice should not only attach importance to technological advances, but also consider the commercial success rate.

Choi Dong-Tree said: "We are very optimistic about lithium, but in fact, only after obtaining the technological breakthrough will be of great development. For my country, lithium battery technology is not ripe for promotion; while nickel-metal hydride batteries to promote the time was ripe, Ni-MH cost, performance hybrid can basically meet the demand for hybrid vehicles with at a more mature and more economy. "

Cross-industry alliance more with less

For now, although the surface is subject to the policy directly benefit from the care of the nickel-metal hydride battery business, but other domestic companies are not discouraged battery parts because, according to auto industry revitalization plan, to new energy vehicles in 2011, the proportion of new car sales to 5% target, according to sell 12 million years of calculation, at least 60 million units, which should then "rules" as defined in the lithium batteries will also enter universal application stage. The industry generally agree that the next 3 to 5 years will be key components of new energy vehicles the rapid development stage.

However, placed in front of the industrialization of new energy challenges, not the solution far from the road as simple as battery technology, industry experts believe that the majority of primary and secondary components of domestic enterprises due to lack of funds, the basis of independent innovation is weak, in the industrialization of new energy IBM ThinkPad T21 battery vehicles on the road go is not smooth.

In the recently held a battery powered electric vehicle symposium, the Department of Industrial Engineering letter to the Division Office for the Coordination Lee Wan said: "The key components of domestic parts enterprises in production, domestic production of basic raw materials, is currently the development of new energy vehicles key and bottlenecks. "

Planning for the automotive industry to develop "new energy by 2011, the proportion of car sales to reach 5% of" objective, Li Wan-li is not optimistic. He said: "At present there is no new energy auto parts industrial base to the current capacity is difficult to achieve this goal."

Judging from the current situation, in terms of policy stimulus, although the new energy auto parts enterprises have mushroomed to take out, only one place in Guangdong, more than 100 private companies to do nickel-metal hydride batteries, but the surface of prosperity behind it to conceal the degree of lack of spare parts industry crisis.

Even walking in the forefront of the domestic automobile enterprises,IBM ThinkPad T20 battery clearly ahead of the launch of new energy electric cars Dongfeng Nissan Passenger Vehicle Company Ren Yong, vice president, but also new energy-based industries of the current shortage of some solid foundation. Ren Yong told reporters: "Judging from the current understanding of the entire battery industry point of view, a lot of battery companies have done a monomer for the battery-depth research, our single cell in the international community is also doing well, but in the process of sexual battery and thermal management, a relatively big gap, "Ren said with some concern," the key lies in the new energy automotive components were not formed in industrial production, is not only the motive power batteries, including the industrialization of the motor, basic raw materials, the localization of these two core areas, are not industrial base, which is currently the biggest problem. "

Despite the bottlenecks, but Ren view, the dilemma is not hard to break, "In fact, Japanese industry trends has given us a reference to draw on." Motive power in the realization of industrialization process, the upstream and downstream industry chain battery production enterprises and supplier of complete vehicle, or bundled with the middle of doing so much more effective than a business go it alone. Including Toyota, Honda and Nissan, including OEMs and electronics giant has been formed into an industrial alliance, through the establishment of a joint venture company will bundle the interests of both their respective merits. Ren said: "The composition of such a strategic alliance, not only an effort to raise anti-risk ability, but also share the huge R & D expenses more efficiently IBM ThinkPad X61 battery much more effective."

The number of commodities have been recalled about 22 million. Recalled due to some reasons, the battery can overheat, there are burns caused by the user or cause a fire hazard. Up to now, Griffin International Cos. The company has received six reports of batteries overheating, including two minor burns to users of hands have been.

To this end, the U.S. Consumer Product Safety Commission advises consumers to immediately stop using the recalled batteries Charger suits, Toshiba PA3250U-1BAS Battery and with Griffin International Cos. Contact the company return and free replacement of other commodities.

In the National Natural Science Foundation of Science and Technology as well as the introduction of foreign Chemistry, Chinese Academy of Sciences Outstanding Young Talents Scheme with the support of Chemistry of Molecular Nanostructure and Nanotechnology Laboratory Institute researchers successfully developed a super-fast charging and discharging capacity of The LiFePO4 / C micro-composite structure sodium lithium-ion battery cathode material. Results were published in the near future Adv. Mater. (2009, 21, 2710-2714), the Energy Research News Web site was reported.

The Task Force study the long-term Toshiba PA3356U-1BAS Battery commitment to inclusive micro-structure study of electrode materials for lithium storage. In the preliminary work in which they put forward the "three-dimensional mixed-grade conductive network" under the guidance of electrode material design ideas, through the build out of both nano-and micron conductive network structure of three-dimensional mixed positive and negative materials, greatly enhanced the lithium-ion batteries energy density and power density (Adv. Mater., 2008, 20, 2878; Adv. Mater., 2007, 19, 2087; Chem. Mater., 2008, 20, 3617). More recently, they are satisfied that micro-structure through the design and increase the carbon-coated alloy anode, carbon anode and oxide anode materials for lithium storage capacity, performance and cycle performance magnification (Adv. Mater., 2008, 20, 1160; Adv. Funct. Mater. 2008, 18, 3941; Electrochem. Commun., 2009, 11, 1468; J. Phys. Chem. C 2009, 113, 14213)Toshiba PA3291U-1BAS Battery .

On this basis, they designed a three-dimensional network structure mixed conductive electrode material (Figure 1b), and successfully, on LiFePO4 cathode material has been verified (Figure 1a). In the study, researchers will be uniform LiFePO4 nanoparticles embedded in porous carbon (Fig. 1a), developed a magnification-performance composite cathode materials.

Battery usher in "Lithium Iron" era

A time when the summer people who travel a sudden increase in the number they encountered the dilemma: digital cameras, Toshiba PA3166U-1BAS Battery patting a photo it suddenly is dead. Recently, one for digital cameras, camcorders, SLR cameras and other products, high-energy lithium-ion batteries coming to market, to solve this problem: the battery discharge performance reached a surprising degree, is the widely used alkaline batteries 7 times, the traditional carbon-zinc batteries, 42 times - ushered in a new battery consumption, "Lithium-iron" era.

A lithium iron battery replacement seven alkaline batteries

Lithium-iron battery is a kind of beginning of this century was developed by the United States and Europe to replace the alkaline batteries in high-tech products, because of its unparalleled performance and environmental advantages of the discharge quickly swept up. Battery Technology Co., Ltd. in Guangzhou, when resistance to the entrepreneurs who rely on their own and domestic universities, research institutions the power of talent developed their own proprietary formulations,Toshiba PA3331U-1BAS Battery and exported in large quantities in 2005, was among the first technology in the field occupy the commanding heights of domestic enterprises.

Lithium-iron battery has a high power capacity, suitable for the needs of high-discharge products, such as digital cameras, camcorders, SLR cameras, electric toys, electric shavers, digital electronic products, digital display equipment, medical equipment and so on. Resistance when the lithium iron battery self-discharge is low, storage life of up to 15 years; its light weight, only two-thirds of alkaline batteries; use of high-energy lithium and metallic elements from the natural iron sulfide, lead, mercury content zero, is a green battery. As a resistance when the lithium-iron battery is equivalent to seven alkaline batteries, and can replace 42 carbon-zinc batteries, battery decrease in the number discarded.

It is reported that when resistance to lithium iron battery with any 5, 7 batteries (such as disposable alkaline batteries, carbon zinc batteries), and nickel-metal hydride, nickel cadmium, zinc and silver rechargeable batteries used interchangeably, the ideal cylindrical battery upgrade replacement products, and gradually become a small portable electronic products Toshiba PA3098U-1BAS Battery the best power.

Spawned a huge market hundreds of billion yuan

As the lithium-iron battery in the international community is still cutting-edge technology, and therefore the focus of international giants monopoly of objects, imported brands of lithium-iron battery, priced more than 20 yuan / festival around this price so that consumers "feel powerless and frustrated" - a high price become a high-energy lithium-ion batteries need to cross the threshold of universal access. In order to allow consumers to fully enjoy the local products, Huimin interests of the independent intellectual property rights, anti-commitment when the lithium-iron batteries will be lithium-iron batteries imported brands sold half the price, which will promote the popularity of Toshiba PA3084U-1BAS Battery lithium-iron battery.

Analysts said that with the steady improvement in sales, the scale will be significantly reduced operating costs, future prices of lithium iron batteries are dropped space will eventually be replaced by a wide range of alkaline batteries. According to the China Battery Association statistics, China has become the world's largest manufacturer of batteries and battery consuming countries: in 2008, 246.8 billion yuan industrial output value of the battery, the battery output of about 39.2 billion; in 2007, compared with an increase of more than 40%. The future, large-scale lithium-ion batteries Toshiba PA3399U-1BAS Battery to replace the alkaline battery, and some rechargeable batteries, will result in a huge market for hundreds of billion.

Lithium minerals

Tape scattered strong upside hot real estate market, electric power, Laptop Battery and directed both the performance of additional subjects such as the short-term increases in a larger market due to broader market recovery, high-momentum has clearly diminished accordingly adjusted the full-cap, lower capital inflows is expected to become the main force of hollow, as the two cities ST Meiyan least 600,868 shares of its rich subject matter is speculation into our field of vision.

1, water and electricity benefit from rising oil prices leading

Company is the leading electricity and water lowest in the two cities share the recent transfer of the saffron water and electricity Toshiba PA3107U-1BAS Battery companies were 738 million stake in a huge return on investment companies are striving to achieve the 2009 income of 320 million yuan hydropower Meiyan The company also holds 100% stake in cement rotary kiln will be achieved cement clinker sales of 180 million yuan as the company's disposal of assets and debt restructuring in corporate profitability is expected to further improve the power and the Yangtze plate full of electricity, led by starter makes company's share price is expected to be activated.

2, into the tremendous potential of mineral

Unit of mineral resources subject matter should not be overlooked. Meiyan mining company recently acquired 100% stake in the Meiyan main silver mining silver ore mining reserves of which 1.322 million tons of silver metal content of 451.86 tons of antimony ore reserves of 1.21 million tons and in the mining of silver ore -60 m below to maintain a reserve of 2.2089 million tons of antimony ore of 1.4098 million tons worth looking forward to the prospects of its mining in Yunnan Copper Toshiba PA3383U-1BAS Battery Industry with the recent mining stocks led the overall company's share price surge is expected to be the main body of the large-scale sweep plate.

Third, lithium foil in short supply

5, supporting a strong break just around the corner

The company also holds 494 million shares of initial offerings Guangdong Hydropower value of its stake in subject matter should not be overlooked. 2 shares of stock on the market is very active and showed its own run-ladder unit volume significantly larger trend of recent signs of the main entry is obvious due to its strong mineral, lithium electricity and venture capital topics Toshiba PA3191U-1BAS Battery than a dollar per share, only 3 out of ST Meiyan expected upside can take an active interest.

Lithium high ground battle heating up in the Mainland there is a great distance away from mass production

Lithium high ground battle heating up in the Mainland there is a great distance away from mass production

September 11, known as "cash cows," said Foshan Lighting [8.59 -1.26%] (000541.SZ) dell Inspiron E1705 battery announced that the proposed joint venture with partners in the development of lithium carbonate in Qinghai to get into the hot new field of energy. Qinghai Salt Lake in lithium resources have a unique advantage. Prior to have two listed companies, CITIC Guoan [18.25 0.39%] (000839.SZ), and Qinghai Salt Lake Potash [56.90 -0.52%] (000792.SZ) to get involved, and deep plowing a long time.

At present, several companies involved in lithium carbonate industry, is only produced by industrial-grade lithium carbonate, the higher the purity requirements of battery grade lithium carbonate is not mass production, a battery grade lithium carbonate to compete for the high ground of the encounter has been quietly launched.

Technological bottlenecks

For the successful production of lithium carbonate, the two factors are indispensable: lithium-containing mineral resources, and mature production processes.

Foshan Lighting The announcement shows that the joint venture is the use of Qinghai Salt Lake brine extract lithium carbonate by drawing upon the technology. dell G5260 battery China and Europe project with the Technical Advisory and Project Development Company Limited's international patents, patented technology known as "salt solution obtained from the lithium chloride method and the implementation of this method of equipment."

The company said, using the technology to extract the lithium content of up to 99.3%, exceeding the national target 98% of the provisions of 1.3 percentage points to reach the international advanced level. But the announcement also said, "the joint venture does not involve mineral resources."

In response, an analyst at Guotai Junan Sang Yong-liang told reporters that because of the different salt components contained in the requirements of the different pairs of processes varies widely, from the Bulletin Board to see, they use patents to its selected target lake how strong dell D5318 battery the current is still unknown.

Foshan Lighting Deputy General Manager's office for this call, company officials said lithium carbonate in Foshan Lighting is a strange industry, must rely on partner technologies. This technology a few years ago related to Salt Lake in Qinghai tried, and passed the test.

From the current industry, practically speaking, lithium carbonate production process as a whole is not mature enough.

Sang Yong-liang said that in the lithium carbonate production, there are two kinds of processes, ore extraction and salt brine extraction, ore extraction process maturity, but the high energy consumption, heavy pollution and high cost; salt lake brine lithium content extraction has the advantages of high and low-cost However, the high technical difficulty. dell 310-6322 battery At present domestic production or in the main ore extracting lithium, but lithium brine to mention technology is the future direction of development.

Current production lithium carbonate enterprises are mainly CITIC Guoan, Tibet Mining [23.20 -1.11%] (000762.SZ), Salt Lake Potash ore extraction technology, as well as experts in the way Raymond shares [19.30 -1.53%] (002192.SZ). Sang Yong-liang said that listed companies from the relevant situation, the salt lake brine extraction techniques are to be improved, technology is not good, not necessarily the cost of extracting ore than using the traditional low.

Qinghai, a local source said that if the perfect Foshan Lighting's patented technology, widening the distance, and other colleagues mention.

Other listed companies have also been struggling to break through the bottleneck. With CITIC Guoan, for example, September 8, the company opened announcement and Chengdu Aircraft Industry Company, is planning to launch later this year battery grade lithium carbonate products in order to obtain a higher price. China Merchants Securities [99.70 -0.01%] Zhang Zhihong that the current has stabilized the company's lithium technology is expected to double this year, next year's output can be compared with more than 1.2 million tons, dell 310-6321 battery long-term up to 2 million tons.

Lithium-Ion battery is still "yourselves"

Support the major listed companies competing to enter the lithium carbonate industry is its lithium batteries for future applications will be of great development of the pre-sentence: the world's major vehicle manufacturers have a clear development of electric or hybrid cars ambitious plan.

Golden State Securities [21.77 -1.98%] automotive industry researcher predicts the next 10 years, the development of new energy vehicles in China demand for lithium carbonate compound annual growth rate will reach 40%, from 1,500 tons less than in 2010 increased to 2015, nearly 10000 t, 2020 more than 40,000 tons.

However, the Chinese Renewable Energy Society, vice president dell Inspiron 9400 battery of Mengxian Gan told reporters that the new energy vehicles still have many questions to be resolved, there is a great distance away from mass production, the most important thing is to increase scientific and technological research and development on all aspects of efforts, including the in battery production.

A senior industry source said, in 2008, the domestic battery is mostly produced by OEM (processing), first because of China's current extraction technology can not be used in the formation of lithium carbonate scale; 2 is due to the current purity of self-produced lithium carbonate enough, can only be used for some of the purity less demanding areas, such as aluminum smelting, ceramics and glass, alloy and agriculture.

State Securities Wang Xiaoying Jin pointed out that lithium carbonate has a high resources, financial and technical barriers, the domestic legal system in order to extract the salt lake brine lithium carbonate firms such as CITIC Guoan, a mining plan in Tibet are still not fully up to capacity.

CITIC Guoan plan by the end of 2009 to produce battery grade lithium carbonate in 2010, 5,000 tons; Tibet in 2008 a loss of 14 million yuan mining Zabuye lithium industry in the production of lithium carbonate and lithium hydroxide is only 1556.5 tons, which is not the battery level.

Tibet Mineral insiders also told reporters that they are now the purity lithium carbonate is 60% -65%, that is not yet reached the battery level, dell Inspiron 9300 battery the future whether or not to expand in this direction depends on government support and funding efforts in the circumstances.

Two are considered the most "Lithium" concept of the listed companies there is no battery-level products, which means that, in China's listed companies, the so-called "lithium concept", is output in the absence of lithium battery-level when the capital market by virtue of a listed company, "yourselves" interpretation of the karate.

Foshan, broke into the lighting, as well as the enterprising CITIC Guoan to this dilemma may be a breakthrough. Foshan Lighting near a high-level source said, according to Buddhism in Qinghai Lithium Energy Development Co., Ltd. was established, it is estimated under normal production within three years, will work with other lithium carbonate production enterprises in Qinghai have completed an annual output of 5,000 tons to 40,000 tons carbonate lithium (purity above 99.3%), lithium chloride (purity up to 99.3%) dell Inspiron 6000 battery (dell 6000 battery) large-scale production, based on current international market, market, the product will be formed of more than 2 billion sales volume.

However, Sang Yong-liang told reporters that the decision to enter into production between now and at least two or three years time, put into a longer time, its future performance of listed companies remains to be seen.

Activate the "aging" of the battery

2009-12-02T18:33:00.000-08:00

Activate the "aging" of the battery

To show the battery is damaged. Therefore, the battery maintenance and rehabilitation needs Laptop Battery of laptop users is the topic of concern. Maintenance process is also often referred to as "activation", "activation", a very vivid and to reflect that the battery "dead" and rebirth process.

I summed up the activation of a battery approach, its basic principle is that when the charge and discharge currents must be small (but not too small, or too long), there is to try to be filled, put completely. Cell damage because the battery in use after a period of time will "aging" of. Concrete expression of the resistance is bigger, at charging time at both ends of voltage rise faster, so it will be easily found for the charge control circuit has been filled, the capacity also is naturally "down". Since relatively large battery internal resistance, discharge voltage drop by high speed, the system can easily mistaken for a voltage not enough, lack of electricity (in fact, there is no electrical discharge).

As can be seen from the above description of the battery is a vicious cycle of aging process, the discovery of lost working hours, the battery faster than dell 1691P battery when what it should be tempered, or else it will be finished sooner or later. In addition, many lithium battery failure is the battery package of a certain energy-saving result of core failure, a bad pot of soup mouse droppings. This phenomenon can not be avoided, because the battery power-saving core of each character can not be fully consistent with a long time there are some quality, the aging first weakened, undermining the whole (series after) the discharge curve. It simply means that section of bad batteries before charging full discharge also finished first place, but this time the capacity of the other batteries have not been fully utilized.

The core of a power-saving over charge / over-discharge will not cause the battery monitoring circuit that the whole is full of / discharge end of the. For example, when charging other batteries start getting close to full charge when pressed, that section of bad batteries may dell Latitude C640 battery have reached the terminal voltage of 4.30V or higher, resulting in overcharge damage, while others are sufficient dissatisfaction. Editor's note: For internal batteries battery damage, the "Chinese computer education" 2001 No. 2 has a very good article - "notebook computer batteries DIY" worth learning from. Interest, courage and capacity of friends can try to open the battery pack, believe that the help of multimeter, you can quickly find the damaged batteries (voltage abnormality). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product. The battery charge and discharge lithium-ion battery charging poses as a way of fast charge constant current in the voltage reaches a certain value and then to slow charging constant voltage mode. Notebook computers are often not strictly a constant-current charge of monitoring devices.

The system load when a large charge current on small, whereas the large, the current from the AC power adapter power margin decision.dell Latitude C610 battery Clearly, the system will charge the battery and other components, such as CPU, hard drive, LCD and other competing energy sources. I tried to run side Superπ, while charging the way and found that the charge current in the 0.70 ~ 1.70A between the changes, can not meet the lithium-ion battery charging requirements, so I fear that this will work, rechargeable batteries were defective. IBM statement calling for notebook computers will not operate when the charge is probably the reason. Charge at boot time, if we can select the charge mode, you do not choose fast charge mode (Express charge mode), to avoid premature battery "full."

There is a time of low battery power to prohibit the use of the highest dell Latitude C600 battery CPU performance in order to reduce the power of the competition. If the notebook computer's CPU is to support the use of SpeedStep technology, it is best to install the driver (the vendor will be responsible installed) to facilitate the adjustment performance. SpeedStep program icon is a blue flags, right-click performance tuning options it can occur. Under the Windows XP system, SpeedStep program will be problems, this time to rely on or to modify the BIOS parameters of the regulation of a number of brand-specific programs, such as IBM notebook computer software is very powerful tool.

Electric-discharge of lithium, or always-on, let the natural discharge better. Is best not to use physical methods (string of resistors in the class). Not to say that that was not feasible, but relatively large risk, if the internal protection circuit was not working, then set aside the batteries, and the worst is probably the battery explosion, of course, this unlikely. Circuit hidden dangerous is not impossible, a number of big-name manufacturers have found that the design of potential risk factors exist in a battery recall, as mobile phone battery when you do not hear the explosion.

Small knowledge:

In general, notebook computer battery protection circuit in the part is usually voltage block, control chip, insurance, and temperature probes. dell Latitude CPX battery Temperature protection device is usually a one-off, the inside has a fuse (some 130 ℃ Fuse), is used to monitor the voltage regulator block work. If the charge-discharge process exceptions, immediately there will be a current through the temperature protection device, will fuse fuse, the battery's internal circuitry at this time for the open circuit state, and can not be restored. If you want to repair only the replacement of temperature protection device, but such temperature protection device on the market hard to find. Discharge is the discharge current as small as possible, the operation is to slow down and let the CPU, hard disk stops turn, transferred the darkest the screen (or close the switch off), then do not run any programs until the laptop automatically shut down. The emphasis on small-current discharge is to prevent premature detection of laptop battery shortage. I have disabled the hard disk, close the screen, cancel the power of the state police under the laptop dell Inspiron 2500 battery completely discharge (put a close to 6 hours), the battery capacity from 31.72Wh restored to 33.65Wh.

China's BYD, Wanxiang Group, Shenzhen BAK Battery

China's BYD, Wanxiang Group, Shenzhen BAK Battery, Tianjin Lishen Battery Myers, a joint venture Laptop Battery with the United States and so exposure to lithium battery research. However, at present the only master the vehicle lithium iron phosphate battery technology, large-scale production enterprises BYD, the world's leading position, BYD E6 pure electric vehicles and hybrid F3DM has officially launched its own carrying R & D of lithium power battery.

Recently, the U.S. battery companies are stepping up investment in lithium batteries for cars, such as power solutions company, Johnson Controls (Johnson Controls Power Solutions) recently said the company plans to invest 100 million U.S. dollars, in the Florence of Southern California, the construction of recycling car batteries factory. The U.S. government also heavily subsidized Boston-Power investment in electric car battery factory, will be in Auburn, Massachusetts United States to establish the company's first electric car battery dell G5345 battery factory.

2, power problems encountered in the development of lithium batteries

Currently impeding the development of lithium-ion battery power bottlenecks are: safety performance and vehicle power battery management system.

Safety performance, because the lithium-ion battery with energy density and working temperature is high, poor working conditions and other reasons, coupled with the safety of people-oriented concept, so the battery safety of users made a very high demand. Auto power battery management system, since the vehicle power battery voltage is 12V or 24V, but a single power lithium-ion battery voltage is 3.7V, the battery must be by a number of series and increase the voltage, but because of the battery is difficult to achieve completely homogeneous charge and discharge, leading to a number of battery packs in series within a single battery charge and discharge occur imbalance, the battery charge will appear under and over-discharge phenomenon, and this situation will lead to a sharp deterioration in battery dell D5561 battery performance and ultimately resulted in the entire group of cells does not work, or even scrapped, thus significantly affect battery life and reliability.

China auto industry analyst with investment advisers that Sheng-mao, power lithium-ion battery to get a good application, which is technically required from the material, batteries, management systems, taking into account the mechanical processing and other aspects. Therefore, the need for upstream and downstream enterprises to work together with the battery as the core of the material, the management system requests formation of an industry group, more conducive to technological advances and system costs.

3, the prospects for automotive lithium batteries

The future of new energy vehicles instead of the traditional automotive trend will become a necessity, automotive lithium batteries as a new energy vehicles in the "heart" will spawned a huge industry, economic effects. It is understood that the joint lead by the Ministry of Science and dell 312-0305 battery relevant state ministries and commissions will be 3 consecutive years in each of the 10 different cities were put in 1000 as a demonstration hybrid electric vehicle applications. Support for the state departments concerned, will further promote the demonstration and application of hybrid vehicles as a way to stimulate the development of lithium battery technology, as well as key parts and vehicle improvements in technology, new energy for after 2010, laid the foundation of the automobile industry.

According to the Investment Advisor "issued by China's new energy vehicles 2008-2010 Industry Analysis and Investment Consulting report" shows that the situation with China's energy resources and the development trend of the international automotive technology is expected by 2012, annual production will reach a new energy vehicles 1 million, while projected that by 2025, China accounted for regular gasoline vehicle holdings of passenger cars will be only around 50%, and advanced diesel and gas vehicles, bio-fuel vehicles such as the rapid development of new energy dell 312-0306 battery vehicles will be.

(B), the middle cell materials

1, lithium battery materials industry and company analysis of the status quo

Lithium battery materials can be divided into electrode (positive / negative) materials, separator and electrolyte. Li-ion battery cathode material is the core of the current lithium cobalt oxide, lithium manganese, lithium and nickel-cobalt-manganese-based lithium iron phosphate. Ze Yi graphite anode material, solid carbon particle-based; in the middle of positive and negative electrodes while the battery electrolyte and separator.

In the lithium battery industry chain, the current capacity comparison, due to high barriers to entry, lithium battery cathode material is the smallest capacity, which is the whole industry chain, the most promising aspect. Cathode materials currently in production companies are: China Baoan, CITIC Anhe Shanshangufen, BYD.

Compared with the cathode material, anode material for lithium battery costs accounted for dell F5136 battery the proportion of low-and domestic-oriented industries has been realized, the negative electrode materials, graphite, solid carbon particle-based. Currently engaged in lithium battery cathode material production enterprise in China, the top three national security, Shanshangufen, Long Sand Sea capacity, at present anode material able to basically meet the needs of the domestic market, but with the increasing popularity of new energy vehicles, the future market for this one a huge gap in demand will occur.

Domestic battery manufacturers supporting electrolyte has been basically achieved domestically. Main raw materials for the electrolyte lithium hexafluorophosphate, accounting for about 50% of the cost of the electrolyte, its production cost is 10 yuan / ton, priced at 40 yuan / ton, gross margin as high as 75%, but the market was largely Kanto Electric the chemical industry, SUTERAKEMIFA, Morita chemistry, several Japanese companies a monopoly.

Divide the Department of Li-ion materials technology, the highest barriers to a high-value-added material, gross profit margin is usually 70% or more, accounting for 20-30% of the cost of lithium batteries. Accordance with the terms of a car can be used in 1000-2000 m2 membrane. Divide the market is currently a serious shortage of supply, most dependent on imports, dell Inspiron 710m battery the market dominated by Japanese Asahi Chemical Industry, Tonen Chemical, and the United States Celgard dominate. Membrane with a typical "high-tech, high-capital" characteristics, and the project cycle is very long, the investment risk greater enthusiasm for investing in domestic enterprises is not high. At present, the domestic companies able to produce membrane only star-source technology, Jinhui High-Tech two technologies are relatively mature.

2, lithium battery materials, the development prospects of

According to the Investment Advisor "issued by China's new energy vehicles 2008-2010 Industry Analysis and Investment Consulting report" shows that the situation with China's energy resources and the development trend of the international automotive technology is expected by 2012, annual production will reach a new energy vehicles 1 million, while projected that by 2025, China accounted for regular gasoline vehicle holdings of passenger cars will be only around 50%, and advanced diesel and gas vehicles, bio-fuel vehicles such as the rapid development of new energy vehicles will be.

The future of new energy vehicles instead of the traditional automotive trend will become a necessity, dell Inspiron 700m battery power lithium batteries as a new energy vehicles in the "heart" will be spawned huge industrial and economic effects on the battery raw material suppliers and manufacturers who are huge commercial cake.

Investment Consultants in Lee Sheng-mao auto industry analyst predicts that by 2012 the annual production of new energy vehicles will reach 1 million, according to each new energy automotive batteries costs 7 million power lithium battery cathode material lithium iron phosphate 52 kilograms, anode material 41 kg, 40 kg calculation of the electrolyte. 1 million hybrid vehicles will drive the 52,000 tons cathode material, anode material for 41,000 tons, 40,000 tons electrolyte needs. For domestic battery manufacturers, this would be a gross output value of 70 billion yuan of the big cake. If calculated according to passenger cars, this value will increase three times - each hybrid passenger car battery demand is four times that.

(C), the upper reaches of lithium battery materials, lithium carbonate industry analysis

1, lithium carbonate industry status quo

According to Sheng-mao, the global lithium carbonate industry, the status quo, resource threshold high, capacity is highly concentrated. As of the end of 2007, the global lithium carbonate demand for a total of about 93,000 tons, a major international manufacturers have Chile's SQM, the United States and Germany, Chemtall total FMC annual capacity of 78,000 tons, accounting for 80% of global market share. Large-scale production of lithium carbonate as the enterprise must have reserves of lithium resources are more abundant in salt lake resources, mining rights, which makes the resources of the industry with higher barriers to entry; the other hand, the vast majority of the world's resources are high-magnesium salt low lithium-based , and from high-Mg low-lithium brine separation of lithium carbonate in the purification process technology is very difficult to master prior to these technologies is only a few hands of foreign companies, which makes lithium carbonate industry, but also provides many technical barriers. Therefore, lithium carbonate has created the industry's global oligopoly structure.

Lithium Salt Lake in the independent R & D, which provides technology and production process of magnesium on the basis of Dell Precision M50 battery a number of large industrial enterprises in China in recent years in the depths of the Qaidam Basin Zabuye Salt Lake and start building lithium carbonate, magnesium hydroxide and other chemical products production base. The current domestic production of lithium carbonate enterprises mainly in Tibet, mining, CITIC Guoan, Western Mining Group, Qinghai Salt Lake Group, the four companies, while the Tibetan mining and CITIC Guoan has accounted for the vast majority of them, the two companies in 2008 Lithium Carbonate Total output of more than 4,000 tons.

Statistics show that the hinterland of Qinghai-Tibet Plateau is located in the Qaidam Basin, rich in potassium, sodium, magnesium, lithium, boron and other mineral resources, including magnesium chloride 3.1 billion tons, accounting for about 99% of the country to maintain reserves; lithium chloride nearly 14 million tons, accounting for 83% of the country to maintain reserves. In early 2007, Qinghai CITIC Guoan Technology Development Corporation's West taijnar hu-ton lithium carbonate Dell Precision M40 battery project formally put into production in the Qaidam Basin, the West Lake taijnar become an important production base for lithium carbonate.

2, lithium carbonate industry bottlenecks

At present, the global lithium carbonate production capacity is still low, the production costs are high, not really large-scale mining extraction, the company is still looking for more economical and reasonable mode of production, currently hamper the development of lithium carbonate industry is still the biggest problem is the production process technology. In the short term, Tibet, mining and technology in the production of CITIC Guoan is still inadequate, annual output is only 2,000 tons, respectively, representing a lower percentage of main business income is difficult to drive performance increased significantly.

Chinese Academy of Sciences, said Li Jian, researcher, Salt Lake extracting lithium, magnesium technology, to mention a "bottleneck" and gradually formed a breakthrough in industrial production shows that China has Salt Lake with independent intellectual property rights developed comprehensive utilization of resources based on comprehensive development of salt lake resources, access to large-scale production of lithium and magnesium in a new phase.

3, the domestic lithium carbonate production of business analysis

1. CITIC Guoan:

Qinghai CITIC Guoan currently holds 99.375% stake in national security. Qinghai National Security was established in 2003, mainly engaged in Qinghai Salt Lake, West taijnar lithium, potassium, boron, magnesium and other resources of the comprehensive development. West taijnar Salt Lake Qaidam Basin is located in the middle of an area of 570 square kilometers, the liquid resources to reserves of 3.08 million tons of lithium chloride, potassium chloride 26.56 million tons, 1.63 million tons of boron oxide, magnesium chloride 185.97 million tons. Calculated according Dell Inspiron 3700 battery to the design capacity, these resources available to the company for at least 25 years of mining, the potential economic value of 170 billion yuan.

2. Tibet Mineral:

CITIC Guoan holds a lithium-magnesium associated minerals, the past two or three years has not been a breakthrough in technology, mining in Tibet dominant position in the upstream raw materials is quite highlights. The company now has lithium reserves in first in the country, the world's third largest mining rights Zabuye Salt Lake for 20 years. This is the world's only exists in the form of lithium carbonate in natural salt lakes, in addition to the natural bottom of the lake shore as well as the deposition of lithium carbonate, the water content of lithium carbonate in a conservative estimate as high as 200 million tons. The Mg-Li ratio was only 0.02, the anomaly from a high proportion of Mg-Li Lithium brine problems, so in the future benefit from the mining of Tibet has great potential.

3. Western Mining Group

Qinghai Western Mining Group currently controls 74% of the shares lithium industry. Qinghai Lithium Co., Ltd is currently in the East taijnar to meet the capital of Qinghai Salt Lake extracting lithium and utilization of resources industrialization demonstration projects. In October 2007, Western Mining Corporation design capacity of 3,000 tons of lithium carbonate project started for production purposes. After a year of operation and production process transformation and optimization, to September 2008 reached capacity lithium carbonate on the project to achieve, to the current production of lithium carbonate products for more than 1,000 tons, more than 99.5% product quality and achieve low-cost, non - high temperatures and corrosion, no gas, no residue cleaner emissions from large-scale production.

4. Salt Lake Group:

In order to comprehensive utilization of salt lake magnesium, lithium and other resources, "Eleventh Five-Year" period into Salt Lake Industry Group will invest an annual output of 100,000 tons anhydrous magnesium chloride, 10,000 tons lithium carbonate and so on, to build modern high-tech base in the salt industry. Salt Lake Group, a subsidiary of LandTek lithium industry, its processes, including resin adsorption, elution, concentration, membrane separation and carbonization process. Years ago, installed in the front part of the debugging resin adsorption. Lithium concentrations were lower due to brine a large number of brine to enter the resin bed, resin adsorption main problem is water consumption, resin consumption and power consumption, large, and because a substantial change in resin temperature adaptation is not enough, resulting in resin, are also addressing issues such as broken in. It is estimated that the average production of 1 ton lithium carbonate need to consume around 600 tons of fresh water, the average consumption level of renewable pH of about 5% of resin consumption is about 5% each. The cost of production the need for further observation, expects its costs will be 1.5 tons million yuan.

5, lithium carbonate industry outlook

Li Sheng-mao said, from the development trend, new energy cars is undoubtedly the future direction of automotive development, while the lithium battery powered electric vehicles is the best choice. The future market for lithium batteries and battery raw materials, demand is enormous. For this reason, lithium carbonate, once mining extraction technology is a breakthrough, cost-effective reduction to achieve large-scale industrial production, the outlook for the future will be very broad.

According to the Investment Advisor "issued by China's new energy vehicles 2008-2010 Industry Analysis and Investment Consulting Report" points out that by 2012, China had 10% of the new production of the cars are energy-saving and new energy vehicles, according to an annual output of cars will be cars for the 10 million counted, China's new energy vehicles to reach an annual output of 1 million scale. Each new motor vehicle is expected to need about 0.08 tons of lithium carbonate, lithium batteries once the driving force large-scale application of new energy vehicles, the lithium carbonate market potential will be very huge, new energy sources is expected to only 2012 cars on the annual demand for lithium carbonate will reach 5 million tons.

The current domestic price of industrial-grade lithium carbonate to 45,000 yuan / ton or so, battery grade lithium carbonate price of 70,000 yuan / ton or so, high purity lithium carbonate price is as high as 100,000 yuan / ton or more, domestic involved in new projects because it is extracted using salt brine lithium carbonate, production costs in the 10000-15000 yuan / tons. Therefore, the market generally felt that the profitability of lithium carbonate products is very high, will give investors a huge increase.

Summary: 5 years after the lithium battery to replace nickel-metal hydride batteries mainstream

Lithium-ion battery in 2-3 years, although difficult to replace the nickel-hydrogen batteries, Dell 1K500 battery however, not be overlooked is the future of lithium batteries will replace the nickel-metal hydride batteries into the mainstream of new energy vehicles. At present, Japan's leading automotive and battery businesses have invested in building lithium-ion power battery production line, concentrated in the 2010-2011 production. Fuji economy that the lithium-ion battery will begin in 2011 to gradually replace the nickel-metal hydride batteries, lithium-ion battery, as no doubt the future of mainstream technology route.

Japan's "Economic News" recently reported that the Japanese will be the Japanese economy, Trade and Industry as the center of the external groups to develop programs, Japan, Toyota, Nissan, Honda, Suzuki, Mitsubishi, Mazda, Fuji Heavy Industries, Daihatsu, Yamaha, 9 cars, motorcycle manufacturing enterprises and Sanyo Electric, Hitachi, Ltd., Matsushita Battery Industrial, pasona energy, GSYUASA companies, battery manufacturers, along with Tokyo Electric Power Co., Japan Automobile Research Institute, Economic, Trade and Industry, Infrastructure and Transport Ministry and other units will participate in a pilot to develop uniform specifications and safety standards for lithium batteries. Meanwhile, the charging method will also be standardized.

According to Japan Automobile Research Institute is expected, according to the popularity of hybrids is now estimated that by 2020, hybrid car in Japan dell 5081P battery will reach about 360 million. If the high-performance lithium battery for more promotion, usage is likely to further reach 7.2 million level. Media critics said that if Japan can be a new generation of automotive lithium batteries to obtain ISO certification opportunities to master the initiative, and the enterprises will benefit immensely.

In this regard, the investment advisers new energy automotive industry researcher Li Sheng-mao, not without anxiety that, in lithium battery technology is mature, the nickel-metal hydride battery market will be gradually eroded lithium battery, 5 years later, the mainstream nickel-metal hydride batteries will be lithium batteries replaced. Person who, without their finest hour, the current A shares in the torch high in 2010 and 2011, respectively, of their nickel-metal hydride battery production line expansion, its future to face greater risk of investment recovery.

Li Sheng-mao said, technological advances, China's car prices and the related battery business in addition to promoting the industrialization of nickel-metal hydride batteries, more attention should be put some of the long-term, to devote human resources to carry out power lithium battery research and development, and to maintain the fuel cell technical follow-up, in order to occupy a broader new energy car market ready. China's traditional vehicle for at least 10 years behind the Western countries, however, new energy vehicles as an emerging area of new energy vehicles are becoming the world's auto industry to catch up with China's auto industry a rare technology "leapfrog" opportunity for domestic enterprises want to be able to to seize dell 75UYF battery the opportunity to emerge in the next round of the automotive industry.

In the development of new energy vehicles

2009-12-01T18:46:00.001-08:00

In the development of new energy vehicles

In the development of new energy vehicles, the nickel-metal hydride battery technology the most mature in the next dell Latitude D510 battery three years, will remain the mainstream of new energy vehicles, followed by nickel-metal hydride battery technology and lithium iron phosphate, hydrogen fuel cells, one-third of the world, five years will be gradually lithium batteries and fuel cells are replaced. Battery giant Panasonic and Sanyo also found that the lithium-ion battery can not be replaced in 2 ~ 3 years, nickel-hydrogen batteries, mainly due to cheaper nickel-hydrogen battery safety, has reached large-scale production. Lithium batteries also need to continue to research topics, such as security, so take time commercial.

According to Japan's Fuji economic analysis, the mainstream nickel-metal hydride batteries will be able to continue until 2011, but after 2011, Li-ion battery will gradually erode the market share of the nickel-metal hydride batteries, the agency predicted in 2009 Ni-MH rechargeable battery-vehicle global market scale than the previous year by 23.7% to ¥ 92,000,000,000, but the 2015 Ni-MH rechargeable battery-vehicle market will fall to ¥ 55,000,000,000.

Part II: Dynamic Analysis of investment opportunities in the three dell Latitude D505 battery lithium batteries

I. Analysis of lithium batteries

The traditional lead-acid batteries, nickel-cadmium batteries and nickel-metal hydride battery technology itself is relatively mature, but they are used in automotive batteries as a power, then there exists a larger problem. At present, more and more car manufacturers to choose from lithium batteries as a new energy car battery power.

Li-ion battery has the following advantages: small size, light weight, high voltage (which is nickel-cadmium batteries, nickel-hydrogen batteries 3 times) than the energy of large (up to 165WH /? K, is a Ni-MH batteries 3 times), cyclic long-lived, self-discharge rate is low, no memory effect, no pollution, safety and good.

At present many well-known car manufacturers are working to develop lithium battery powered vehicles such as Ford, Chrysler, Toyota, Mitsubishi, Nissan, Hyundai, France, Courreges, Ventury so. While the domestic car manufacturer BYD, Geely, Chery, Lifan, ZTE and other car firms also have their own hybrid and pure electric vehicle powered by dell Latitude D500 battery lithium battery power.

Investment advisers, based on years of monitoring data, as well as communication and related companies, the automotive lithium battery development, market size and future trends in-depth research, summed up study found that, from the development cycle, the current automotive lithium battery market is out of the start-up stage and started into rapid growth stage.

2, lithium batteries on the downstream industry and company analysis

Power battery industry chain including upstream cell non-ferrous materials, suppliers, midstream and downstream manufacturers battery materials lithium battery manufacturer in China. Of these, lithium iron phosphate power battery cathode materials, the most promising investment opportunities, while the key raw material in lithium iron phosphate is lithium carbonate, lithium carbonate derived from the mineral resources, in the nature reserves are limited, with strong regional and scarcity, are scarce resources. dell Inspiron 600m battery Thus, in the new energy automotive industry chain, lithium carbonate becomes the strategic importance of resources is particularly prominent.

(A), the downstream manufacturers of lithium batteries

Li Sheng-mao said the investment adviser, cars lithium battery industry contains a very large value of the potential electric car battery materials upstream suppliers and downstream manufacturers of automotive lithium batteries for automotive operations have been tiptoeing around a long time. Li-ion battery is behind the hot car prices on the plug-in hybrids (also known as plug-in hybrid electric vehicles) and pure electric vehicle market prospects of the recognition and R & D capabilities of their current concerns. While the Bosch stand out by the end of 2008, said to be electric cars on the heat to keep sober, but even cool, such as Bosch, has also set up a joint venture with Samsung plans to achieve volume production and sales in 2011.

1, the Sino-Japanese and American auto lithium battery development situation analysis for

According to Deutsche Bank research shows that vehicle the following 10 companies most willing to work with companies to develop automotive lithium battery: 1) Johnson Controls-Saft (the United States and France, Johnson Controls and Saft joint venture); 2) A123 Systems, Inc. (from the Massachusetts Institute of Technology College, General Electric and other investors to set up the company's group of co-operation with the mainland); 3) LG Chemical (the company's U.S. subsidiary Compact Power); 4) EnerDel (Ener1 and Delphi joint venture); 5) AESC dell Inspiron 510m battery ( Nissan and NEC joint venture); 6) PEVE (a joint venture between Toyota and Matsushita); 7) GS Yuasa; 8) Hitachi; 9) Sanyo Electric; 10) Samsung.

Investment Advisor in the new energy automotive industry researcher Li Sheng-mao pointed out that the research can be found from the above, at present, the Japanese lithium battery suppliers in the global market indeed account for a large advantage. According to the Japanese after the disclosure of the Industrial Policy Bureau, Japan in 2010 will strive to lithium batteries for next-generation electric vehicles. Toyota, Nissan and Matsushita Electric Industrial and other related companies signed an agreement to jointly develop a new generation of unified specification cars lithium battery, and plans to mass production within 2 years. Toshiba decided to spend ¥ 50,000,000,000 development of electric vehicles using lithium-ion batteries, which will be held within two years of high-performance power into semi-commercial production.

In recent years, China's automotive lithium battery industry, from scratch, from small to large, rapid development, production capacity after Japan. China's lithium-ion battery industry began late in Japan, but developing very fast, in power lithium-ion battery research and development has also invested a great deal of financial and material resources. China's automotive lithium-ion battery R & D project has been the national "863" key project, much of the material to achieve the localization and the introduction of multi-national dell Inspiron 500m battery has been self-built production lines and supporting materials, factories have more than one, have been the formation of large-scale production, highly competitive market, primarily investment-driven industries.

2009 New Energy Automotive Battery Industry Analysis

2009-12-01T18:45:00.001-08:00

2009 New Energy Automotive Battery Industry Analysis

Overview: The Global New Energy Development Path Analysis of Auto Industry

New energy electric car the most important components is the driving force batteries,Laptop Battery electric motors and energy conversion control systems, while the power battery to achieve fast charging, security and other high-performance, high technical threshold, but also the most concentrated part of the profits. Investment Advisor in the new energy automotive industry researcher Li Sheng-mao said that the new energy vehicles demanding on the battery, you must have a high specific energy, high specific power, fast charging and deep discharge performance, and requires the cost as low as possible, the use of Shou as long as possible.

According to the Investment Advisor "issued by the battery industry in China 2009-2012 Forecast of investment analysis and report" shows that the new energy vehicles will be in the "Ni-MH - Lithium-Ion battery - fuel cell" industry-oriented development path. Able to deliver only the short-term performance of nickel-hydrogen batteries, lithium iron phosphate battery immature, as well as the Department of Public letter issued new standards for access to new energy vehicles also made nickel-hydrogen battery manufacturers have seen in the short-term hope. But ,3-5 years in lithium battery dell 1X793 battery technology is mature, the nickel-metal hydride battery lithium battery market will be gradually eroded.

Furthermore, in recent years, fuel cell (FC) and technological advances make the dream of hydrogen become a reality in the 21st century. The hydrogen-powered fuel cell vehicles (FCV) has been the world's governments and enterprises attach great importance to, and has made significant progress, is expected in the next 5 - 10 years FCV will officially enter the market to hydrogen refueling station, Hydrogen transmission pipeline construction, marked "hydrogen economy" horizon.

The study found that the Japanese supplier of lithium batteries account for a large dell 6Y270 battery dominant position and has begun to formulate a unified lithium battery specifications, safety standards, charging. By the United States so as not to become dependent on imported oil to foreign dependence of lithium batteries, but also to support electric cars and lithium battery manufacturers, the U.S. Department of Energy, also approved a 25 billion U.S. dollars last year in loans. By comparison, automakers in Europe while in the green energy-saving environmental protection is very radical, even more radical, but they are in improving the conventional engine (such as its "small", the use of gas / diesel direct injection technology), the or hydrogen-powered vehicles, more obvious advantages.

Part I: Policy Ni-MH battery usher in investment in good feast

Investment Consultants in industrial research center was informed that the June 25 letter to the Ministry of day laborers released the "new energy automobile manufacturing companies and product access management rules", and was effective on July 1 to December 31, 2010 apply. Investment Advisor in the new energy automotive industry researcher Li Sheng-mao said, according to the Ministry of Public letter issued new standards to nickel-metal hydride battery production hybrid passenger car is classified as a mature product that allows nationwide sales of the use of pairs of dell 312-0068 battery nickel-metal hydride battery industry is a big plus.

I. Analysis of nickel-metal hydride battery development

Nickel-hydrogen battery has just entered the mature stage, is currently used in hybrid electric vehicle battery system, the only real validation was commercial, large-scale battery systems, the global mass-produced hybrid car has been used in all nickel-hydrogen battery system.

According to the Investment Advisor "issued by China's new energy vehicles 2008-2010 Industry Analysis and Investment Consulting Report" report shows that 99% of the current hybrid battery market share for the nickel-hydrogen batteries, commercial representative of Toyota Prius. Currently the world's leading vehicle power battery manufacturers are mainly in Japan PEVE and Sanyo, PEVE Global Hybrid-powered cars occupy the Ni-MH battery 85% of the market share, is currently the main commercial hybrid cars such as Toyota Prius, Alphard and Estima, as well as the Honda Civic, Insight Dengjun used PEVE nickel hydrogen batteries.

At present, the Chang'an Jie Xun, Chery A5, FAW Pentium, General Grand Hyatt brands such as model cars have been running, they are also used in nickel-metal hydride batteries, but batteries are purchasing from abroad, the domestic nickel-metal hydride batteries in the car on the use of match is still dell Latitude D610 battery in development stage. Keli Yuan is currently working with the domestic Chery Automobile, Chang'an Automobile and other co-operation, the first production line of products are mainly supplied Chery Automobile.

2, Ni-MH battery industry and company analysis

In the field of nickel-hydrogen batteries, China in technology and resources are an advantage, in which performance of the world's leading nickel hydroxide, rare-earth rich in natural resources, has unique advantages in resources, therefore, the development of nickel-hydrogen battery is the country's most realistic option.

Investment Advisor in the new energy automotive industry researcher Li Sheng-mao that from Ni-MH battery industry chain perspective, the upstream raw material manufacturers for the metal mineral mining companies, mid-stream for the nickel-metal hydride battery materials supplier, downstream of the battery manufacturer. From a more optimistic view of the industry chain downstream manufacturers, the current state of competition in the upstream firms supply-demand balance, but the battery power is far downstream and midstream Keli Torch High-tech manufacturers are in short supply in the state.

Nickel mining in the upstream business with Jean-nickel industry, while the middle reaches of producing nickel-metal hydride battery materials, domestic listed companies, including Jinrui Technology (cathode material for nickel hydroxide), Xiamen Tungsten, and Baotou Steel Rare-earth (RE anode materials for hydrogen storage alloy powder ), dell Latitude D600 battery in which Xiamen Tungsten is the Ni-MH battery production of hydrogen storage powder leading enterprises, but also involves the production of lithium battery cathode materials, with good room for development.

Downstream firms, the domestic production capacity with a nickel-hydrogen battery or plan to enter the field include Chunlan Group, Ke-li Yuan, the torch high-tech, Hunan Shenzhou, Kane shares, etc., which Chunlan Group is the nickel-hydrogen battery technology HEV leader in its market share in a leading position in the torch high-tech and Hunan Shenzhou has possessed a certain amount of technical base and market position, whereas a force far and Kane Share The main products are still limited to the single battery, power battery project under construction or under construction, the prospects unclear.

Third, the prospects for nickel-metal hydride batteries

Li Sheng-mao said that with the international oil price rose to 70 U.S. dollars, the new energy vehicles the advantages of starting to show. The world's crude oil supplies tight and prices continued to rise, government, research institutions and enterprises to accelerate the development and promotion of new energy vehicles for the direct driving forces. At the same time, the International Energy changes in the environment, but also for new energy vehicles (currently mainly hybrid cars) enters the stage, creating market dell Latitude D520 battery conditions.

New energy production capacity is determined by the market excess

2009-11-30T18:53:00.003-08:00

New energy production capacity is determined by the market excess

Recently, the "excess capacity to say" to the whole industry has brought new energy shock Laptop Battery, a variety of voices followed. For a time, prospects for the development of new energy industries in the number of uncertain factors.

China's new energy industry, the existence of excess capacity, how will the future development? With these questions, this reporter interviewed a few days ago the State Department counselor, China Renewable Energy Society for Shi Dinghuan.

"Excess of that" biased

At present, including large hydropower, renewable energy, including energy consumption in China's 2.6 billion tons of standard coal in the proportion of less than 10%, while in 2020 this ratio reached 15% important, when the demand of China's total energy consumption likely close to 40 million tons of coal. Clearly, to achieve that goal still a considerable distance. In such a dell Latitude D620 battery situation, the new energy "excess capacity to say" how can one talk? Shi Dinghuan, spoke directly to the hearts of questions.

"New energy production capacity is surplus, should the market to a conclusion." Shi Dinghuan to suffer overcapacity question of polysilicon, for example, using detailed data analysis of its market status. He said polycrystalline silicon photovoltaic solar cell industry chain, a link, different from the balance to unbalanced links, from unbalanced to balanced is a relative dynamic process, this process is regulated through the market.

First of all, from a global perspective, in 2008 the world's polysilicon dell RC107 battery production 6.49 million tons, of which 24.4 thousand tons of electronic grade polysilicon, solar grade polysilicon 40.5 thousand tons. In 2008 the global solar cell production to 7900 megawatts (MWp), in which thin-film battery output 895 MWp, crystalline silicon battery output of 7005 MWp. Solar grade polysilicon in accordance with the 2008 consumption level of 8 tons / MWp standard solar grade polysilicon in 2008 the total demand for 56.04 thousand tons. In a portion of electronic-grade polysilicon to single crystal silicon material in the form of head and tail into the photovoltaic field, which accounts for electronic-grade polysilicon 1 / 10, that is, 2440 tons, so the actual demand for solar grade polysilicon for the 53.6 thousand tons . This 2008 production of solar grade polysilicon compared to 13.1 thousand tons are still missing. Thus, until 2008, the global polysilicon continues in short supply.

Specific to China, in 2005 years ago, China's polysilicon industry was virtually nonexistent. At that time the only one to survive China's polysilicon dell Y9943 battery production capacity of enterprises is only an annual output of 100 tons, far below the global polysilicon industry, and above every turn-kiloton scale. In recent years, strong demand in the global PV market pull, as well as the efforts of industry, our country has finally established its own polysilicon industry, has started production of polysilicon production line using closed-circuit loop, clean production processes and Siemens, improved technologies, and reached a production capacity of 1000 tons and above, some enterprises has reached the level of energy consumption 150-170 kWh / kg (kWh / kg).

China Renewable Energy Society statistics show that in 2008, China's polysilicon production was 4721 tons, compared to 17.85 thousand tons of market demand, is still a lack of 13,129 tons; in 2009, China's production of crystalline silicon cells will be about 3500 MWp, dell Inspiron 640m battery In accordance with 7.5g/Wp terms, total of 26.25 thousand tons polysilicon, while in 2009 China's polysilicon production is estimated at 1.3 million tons. Clearly, there is still more than half of polysilicon to be imported.

Shi Ding-huan said that although China's tight polysilicon supply situation is easing, but the actual demand and supply perspective, does not exist so-called "excess capacity."

"Excess capacity to say" Behind the

Since there is no "excess capacity", the new energy "excess capacity" was another come from? In this regard, Shi Dinghuan analysis, "capacity" concept is one of the main unclear.

Generally speaking, capacity refers to a product line or a business, an industry already have, or the formation of production capacity, actual production dell Inspiron 630m battery capacity, can not be planned capacity, design capacity and capacity under construction, confused.

Shi Dinghuan, for example, a production line under construction in the actual production capacity is zero; a production line has just started production of the actual production capacity and design capacity is also completely different. If a design capacity of 1,000 tons of polysilicon production enterprises in the start of the first year of production of 200 tons, then the year to achieve the actual production capacity is 200 tons, not statistics of 1,000 tons.

Shi Dinghuan pointed out that the shortage in the market situation, a business then the actual production may exceed its design capacity, because in short supply, the plant is at full capacity, so no matter how much of its design capacity, should use the year to measure real output; in excess of dell 6T473 battery demand, the products unmarketable, there is underemployment, the actual output will be less than the capacity.

Shi Dinghuan emphasized that the capacity, design capacity and capacity under construction, with many uncertain factors, should not be a reliable basis for industrial development.

The development of new energy long way to go

The development of new energy industry is to achieve a low carbon economy and sustainable development, the only way, however, at present China's new energy in the composition of the proportion of energy consumption would be minimal. The urgent need for new energy industry, government and society for the understanding and support.

At present, China's new energy industry development is faced with supporting infrastructure, imperfect, the market can accommodate a number of factors are not high degree of constraints, there have been some problems.

Shi Dinghuan believe that no matter how many problems, disputes the extent of substitution should follow the national energy strategy, adhere to the "new dell Inspiron 5100 battery energy sources to replace traditional energy sources to edge alternative energy scarce energy sources to renewable energy alternative to fossil energy" development.

Shi Dinghuan pointed out that in the process of development of new energy industries, the Government should play a basic role of market regulation at the same time, strengthen macro-control and guidance, in particular, to strengthen the construction of science and technology innovation system to form by engaging in basic and strategic research " national team "and the enterprise as the mainstay, combining production and research team composed of technical innovation army of scientific and technological innovation.

At present, China's new energy business a lot, but the R & D investment and talent are dell Inspiron 1100 battery more scattered and difficult to form a strong, country-level research team. Focus on the future development of new energy industries, the Chinese Renewable Energy Society is co-related organizations to build Beijing Solar Electric Power Research Institute.

In the Shi Dinghuan view, this is a new industry in exploring the development of supporting methods, both for government decision-making services, but also to provide assistance for the enterprise technology; both a major strategic research, to focus on development of basic and cutting-edge technologies, but also the implementation of Important information collection, analysis and publishing, and strive to create an open, network-oriented public R & D platform.

"I hope it will develop into the field of solar power in China's 'national team', led the development of solar energy industry, thus contributing to a whole new energy dell C1295 battery industry development." Shi Ding-wan, said.

China-ASEAN cooperation to promote new energy and renewable energy development and utilization of

China-ASEAN cooperation to promote new energy and renewable energy development and utilization of

26, held in Kunming, the "China - ASEAN's new energy and renewable energy dell Latitude D820 battery development and utilization of international S & T Cooperation Forum" to deepen the new energy and renewable energy co-operation developed into a participating government officials and experts consensus.

Association of Southeast Asian Nations Secretariat, the Director of Science and Technology Li Yi Lake Andreas Beam said that China and ASEAN countries have a wealth of new energy and renewable energy resources, in the field of development and utilization of context, countries have accumulated a more fruitful and experience , in order to carry out in-depth in this dell TD175 battery area of cooperation has laid a good foundation.

Department of International Cooperation of Science and Technology of China, said Wang Qiming Counselor, at present, China's new energy and renewable energy with the world's more than a dozen countries have established R & D, technology transfer and demonstration of various forms of cooperation. China and ASEAN countries in the field of cooperation initiatives, such as China and Thailand jointly organized and implemented for the Southeast Asia, South Asia, building solar dell PC764 battery power system development and demonstration of international scientific and technological cooperation projects.

From China and ASEAN countries over a hundred government officials and experts attended the forum and for solar energy, biomass and other renewable energy technologies and product development applications seminar, understanding of national policies and measures, to share in the the field of technology development and utilization of dell 312-0386 battery findings.

Early in November, the Chinese Ministry of Science and the ASEAN Secretariat have agreed, in the Yunnan Province Science and Technology Department to establish a special platform for scientific and technological cooperation, so that countries can on this platform to share information and knowledge.

In fact, Sony, Sanyo will have a lawsuit against BYD, BYD has finally achieved victory.

Although the imitation to the development of BYD offers a shortcut, but also recognized Wang Chuanfu imitation Laptop Battery is not a long-term solution, the key is to master the core technology, "We do not aim to mimic the product to eventually grasp the target development platform."

Strength in numbers

In addition to "cottage" products, BYD also "cottage" equipment. The company started, Wang Chuanfu decided to produce the battery, but a set of production line easily tens of millions, the yuan, BYD could not afford, but others do not sell. How to do? Their own making! "We are learning techniques, methods, or can explore them. Early, when there is no automation equipment, many products are not be able to do them?" As a result, Wang Chuanfu will restore the mechanized assembly line production of semi-automatic increase in manpower "millet plus rifles" type of mode of production, production lines can be decomposed into a month to complete the process manually. This approach not only solved the soil production problems, but also save a lot of money, dell laptop battery reduce production costs.

From the battery to cars, BYD "cottage" model of the device still continues. Wang Chuanfu said that BYD is now 60% of the battery production equipment is self-development. Not only is the battery production equipment, mobile phones and even car parts are many devices are manufactured in their own, such as the car dies, BYD is their own production. At present, BYD has a section for each industry, manufacture of non-standard, semi-automated equipment, the team dedicated to manufacturing equipment.

For the BYD imitation tactics, we can call "cottage Gong", but Wang Chuanfu think it should be called creative imitation, "Early enterprise financial difficulties, imitation is also a last resort."

The workshop in BYD, a dozen production lines are dell Latitude D820 battery lined up in each production line has a sixty or seventy meters long, sat in front of forty to fifty skilled workers, each person holding the hands of a fixture, fast and accurate to doing welding, labeling and so on. BYD has hundreds of such workshops. To visit the people are shocked that they have never seen so many people work together. BYD's rival Sanyo, Sony come to visit, the more fear.

Sanyo, Sony and other manufacturers workshops are equipped with the most advanced automated production lines, only a handful of workers to operate. Compared with the BYD, the cost of production is much higher, often millions of dollars in a production line is necessary. BYD is not enough money, only to earth approach, the decomposition of an automated production processes, as well as a number of stations, through the home-made equipment, and low-cost skilled workers to complete.

Wang Chuanfu said, "We now have more than 10000 engineers, more than 100,000 workers. In the future the number of engineers to reach 3 million dell TD175 battery or more, the number of workers to reach 30 million to 400,000. I say we want to achieve by 2025 the world's first Mahayana car sales business, a lot of people do not believe. but my heart is with bottom. I am what basis? by virtue of its people. 30 million more workforce and a large team of engineers, this is my capital. "" I just want to defeat of the manpower advantage with our competitors, because the vast majority of cars still rely on people to do procedures. the Chinese nation's hard work and hard-working, determined that we will become the first in the world. "

Wang Chuanfu the use of cheap labor for mass manufacture of high-tech products, is a typical "human wave tactics." Strength in numbers, Wang Chuanfu industrial manufacturing with Chinese characteristics into the model to an extreme.

"Technical Madman" to the life of traditional car leather

January 12, 2009, the North American International Auto Show dell PC764 battery in Detroit grand opening of BYD's first entry into the main exhibition hall. BYD unveiled its dual-mode electric vehicle F3DM as well as pure electric vehicles E6, Buffett just invest in BYD also arrived at the scene to help out, attracting a lot of attention. "The New York Times" carried a special report on the BYD introduced BYD's electric cars. Energy shortages in the current circumstances, the electric car has become many people's hope.

Wang Chuanfu has said publicly that he claimed in 2025 to become the world's leading automotive industry is not nonsense, because he mastered the subversive path and disruptive technologies.

First of all, BYD-made batteries of its "human sea tactics" and "cottage tactics" transplanted to the car production, such a use of China's abundant low-cost human resources, production patterns, can significantly reduce production costs, making themselves on the market have a stronger competitive.

Second, technically speaking, BYD's electric car technology is a powerful subversive. Professor of economics at Tokyo University, said Takahiro Fujimoto, "In the future pattern of changing the world automobile industry, will be a complete change in the current internal combustion engine system-driven energy or technology." Wagoner,dell 312-0386 battery chairman of General Motors Corporation, admits, "We will see to the current use of internal combustion engines will be eliminated most of this in my career in the automotive industry will be thirty years that have never been the feeling. "

Wang Chuanfu said the world will enter an era of electric vehicles, internal combustion engine will soon move toward the end of the era, all the internal combustion engine automobile production plants that use of technology will be the end, such as four-wheel drive technology, transmission technology, fuel-injection technology and will become milli - no avail, as electric cars do not need these things. This is the world's automobile industry, no doubt, is a subversive revolution. To use the words of Wang Chuanfu, electric cars to traditional cars like the impact of "e-form on the impact of mechanical watches," as strong.

This technology not only for disruptive changes in BYD, China's auto industry as a whole is an opportunity, a chance to lead the world automobile industry. "Electric cars have been a lack of traditional technologies for China's new automotive technology, automotive industry, it is a catch up with Europe and the United States a good opportunity." Wang Chuanfu said.

Research executive director of China's WTO QIAO Liang optimistic that: "In the new energy era, China's auto industry may well lead the world." Chen Qingtai the State Council Development Research Center has also said that China's position in the global auto industry may be a result of new energy sources Auto major changes.

Wang Chuanfu with complete confidence, "the power to replace the fuel, is the inevitable development trend of the automobile industry." F3DM in BYD dual-mode electric vehicle conference, he is full of pride to announce that, "Now has come the era of electric vehicles, while the lead the world automobile market, not American, nor German, but the Chinese people! "

In order to tide the forefront of new energy vehicles, dell Latitude D620 battery Wang Chuanfu not only invested heavily in R & D of electric vehicles, but also personally command the production of electric vehicles. Established at the end of 2006 the E6 electric vehicle project team, he was personally responsible as the total project, seeks to integrate its two core businesses, batteries and car, from the

And lead the world automotive industry. "In doing electric vehicles, I am upbeat and confident. As we enter the automotive industry is mainly made electric vehicles, electric vehicles is the core of the battery. Battery is what we do best, so we firmly believe that art can BYD low-cost, high-quality manufacturing model to the automotive industry, transplant, so that the whole of China and the world automotive competition, a major change in the pattern. "

Killing the Tiger's "Paradox"

Wang Chuanfu entrepreneurial road is full of legendary, he did not by common sense out the card, good at reverse thinking dell RC107 battery and dare to carry out subversive change and practice. "Wearing straw sandals", he Doudao a lot of "wear shoes" big brother, he is his own original "cottage" technology strategy, down a lot of technical "paper tiger."

However, the road is quite smooth start Wang Chuanfu terms of the success of those who have helped him something, such as super-confident, to reinvent the wheel concept, may also be hidden in the development of BYD. After the success of a more self-sufficient Wang Chuanfu whether the enterprise engaging in "say"? BYD is also in development, too arrogant? After the revolutionaries lay Jiangshan, how to construct a new order, how to achieve their own change? These are the Wang Chuanfu should think about. While locked in, but the legislation is much more difficult than the break.

At present, BYD has "a leader in new energy vehicles," the slogan shouted out, "leading the world in 2025" and under the sea has also boasted, and Wang Chuanfu has put himself in a high level. The so-called mad, "wearing shoes" is not easy. Pierce "paper tigers" who themselves may become a "paper tiger", which is a number of dell Y9943 battery fighting the tiger's fate

BYD's head Wang Chuanfu (Wang Chuanfu news, Wang Chuanfu Well), Laptop Battery super-confident, almost arrogant, daring subversion. He spent a short period of eight years time will be less than 20 people, a small workshop into a world's second-largest mobile phone battery manufacturers. Today, the "batteries king" to do "car king", exactly, is "king of electric cars." This time, he can do into

Wang Chuanfu, BYD young head, human

Referred to as "Lunatic Fringe", "car Madman", "subversives." He was extremely obsessed with technology, meaning everyone made against the car, building electric vehicles, also claimed in 2025 to become the global automotive industry leader.

Most insurgents have a crazy temperament, do not follow common sense, dare to think Gangan, courage, Wang Chuanfu is true. In his eyes, "all are a paper tiger,"Dell Precision M60 battery everything can subvert, everything can change.

How dare people how much production

August 9, 2007, in Shenzhen Longgang, Pingshan base BYD completed, the base area of 1.8 million square meters, a total of more than 30 leveling hills, filling more than 120 fish ponds, dug more than 750 million cubic meters of soil ; base is equipped with power plants and 56 manufacturing plants, tens of thousands of employees in the production line busy; BYD F6 second paragraph of a new car off the assembly line from here, official debut ... ... look at all of this, BYD Wang Chuanfu head can not help but pride of the big time, making remarks in the passenger area of BYD in 2015 to achieve China's first, in 2025 to do in the world. Such pronouncements, and for a shock outside dell Inspiron 8600 battery the industry.

The Tsuboyama base built Twelve years ago, 29-year-old Wang Chuanfu had just resigned from state-owned enterprises and stability, and a dozen business partners in Shenzhen, a dilapidated workshop Liantang 敲敲打打. That run-down shop is almost all of them places of activity during the day and engage in research and development, play ground floor at night. This is the beginning of Wang Chuanfu business. For the resignation, Wang Chuanfu that did not hesitate a firm can do it themselves. When he was borrowing money to the cousin, Xiang-Yang Lü venture, the Xiang-Yang Lü difficult to understand, "You are a national cadres, why risk it sea?" Wang Chuanfu stubbornly insists that "I am a study of the battery, I believe he can do, I believe that the potential of the battery industry. "

The 20th century, the mid-90s, cellular phones popular in the city, Wang Chuanfu sights on mobile phone battery is a huge emerging market. Happened at this time, Japan announced that Japan's domestic production will not nickel-cadmium batteries, Wang Chuanfu think this is a "golden" opportunity, decided to produce nickel-cadmium batteries. dell 8N544 battery Despite the difficulties, but Wang Chuanfu was firmly put into the production of nickel-cadmium batteries, and in the end of 1995 was at the time of Taiwan's largest manufacturer of cordless telephones DBTEL orders.

In 1998, the Asian financial crisis struck, the global battery price drop, BYD, low-cost advantage brought into full play, Philips, Panasonic and so turned to BYD purchase batteries. In just three years, BYD has become the industry leader in the battery.

Subsequently, the BYD higher technical difficulty involved in nickel-metal hydride batteries and lithium battery production. In these two areas are also dominated by Japanese companies, a small company established only three years to challenge the Sanyo, the world's giants, can not help but joke, but Wang Chuanfu was done, and have been successful. At present, BYD nickel batteries, cell phone use lithium batteries in the global market share have been accounted for the first one, BYD become the world's top two mobile phone battery manufacturers.

After all, the battery industry development space is limited, the dell Inspiron 8500 battery ambitious Wang Chuanfu wanted to find a big business to do. Do? "After much deliberation, only the car." This is really big business - industry, the high threshold of significant investments at greater risk. Wang Chuanfu investment in the automobile industry in favor of the little people, company executives are playing a lot of pulled out. In early 2003, Wang Chuanfu before the decision to intervene in the automobile industry to seek the views of more than 20 shareholders, we did not openly opposed, but many people minds disagree with. Xia, general manager of BYD Auto Sales Company is a firm opponent of the ice rule, "too risky to enter a new industry like the automotive, Europe and the United States in front of Japan and South Korea have so many good competitors, and my heart there is a nameless fear." Xia Zhi-Bing Wang Chuanfu has been persuaded to give up.

In addition to internal opposition, external pressure will be greater. Heard BYD wants to build a car, many investors felt inexplicable fear and anger, have asked to call Wang Chuanfu. A U.S. fund to Wang Chuanfu a phone call said that if Wang Chuanfu insist on making cars, they will sell a large number of shares of BYD. In fact, many people are doing, dell Latitude D800 battery and BYD's market value evaporated in just a few days more than 30 billion.

Wang Chuanfu is not for the dynamic pressure. Car, put it bluntly, is just "a pile of iron and steel"! In his view, no need to build cars have a "technophobe", "firm conviction will definitely win, faltering that the opportunity will be wasted away." Wang Chuanfu abnormal firm commitment to building cars, he said many investors, " I Xia Bansheng to do a car. " He bought a lot of cars in the books, plunged into them, and he wanted to in-depth understanding of the industry, and then "go full steam ahead" development.

January 23, 2003, Wang Chuanfu acquired Xian Qin Chuan Auto Co., Ltd. 77% of the shares, formally entered the automotive industry.

Although many people expressed doubts about Wang Chuanfu repairer, but BYD introduced the first model - BYD F3 has achieved impressive market performance, the annual selling 10 million vehicles in the automotive industry for BYD the development of fired the first shot. Subsequently, they have introduced BYD F3R, F6 and other models in the automotive market will be basically established a foothold.

Wang Chuanfu not satisfied with this, his real dream is to produce dell 312-0393 battery electric vehicles, to subvert the pattern of the world's automotive industry. He declared, "For us, the repairer just the same as making toys."

Wang Chuanfu super-confident, almost certain arrogance.

The so-called technical problems, Wang Chuanfu not the slightest fear. Just business, he was put into production the core components of the battery batteries of this high-tech products, to build lithium batteries, building cars, he had never felt timid. Wang Chuanfu venture partner, Sun 1 algae once said, "We never felt afraid of the technology. Others have it, I dare to do; others not, I dare to think. BYD any one manager should have a who but myself will certainly win courage. Whenever a problem, we will say that you can not solve, not because there is no capacity, but because you lack courage. "

In management, Wang Chuanfu also not drift, he publicly expressed no interest in any management books, management books, difficult to answer that all enterprises face unique problems. Even China Central Television asked him to worship by many Chinese entrepreneurs, and Jack Welch, Michael Porter, a dialogue with Taiwan, he also Landelikuai, dell YD626 battery "Michael Porter are?" "Jiekeweier Qi are? "" I know what my business is like, I know how to lead BYD. "compared to experts, Wang Chuanfu even believe in themselves.

For his entrepreneurial success, Wang Chuanfu said, "The most important thing is to have spirit of adventure," and many times is not that you can not do, but because you dare to do.

"Cottage Gong" breaking technical barriers

BYD F3 so popular in one incurred by the introduction of the criticism that its "cottage" traces serious. BYD F3 with the Toyota Corolla, both of very similar appearance, and, BYD F3 components can even GM and Toyota Corolla, so that someone removed a sign of BYD to be replaced by a sign of Corolla.

In this regard, Wang Chuanfu not be shy, but he put that imitation is called "standing on the shoulders of giants", "such as F3, we refer to a number of foreign companies, an excellent brand, we use it for non-patent technology, the patented technology weed out. F3 selling so well is because its design is good. "

In addition to imitate Toyota Corolla F3, BYD F0 and the subsequent launch of the Toyota AYGO shape is also very similar, BYD F6 and Toyota Camry are also many similarities, rather than the price of BYD cars like Toyota cars Type cheaper than half.

In response, Toyota am greatly disturbed by the BYD F3 buy dell MM165 battery why it was so like BYD can be made, while the prices are so cheap? Many people believe that Toyota will be prosecuted BYD, but this thing did not happen.

Wang Chuanfu said BYD though learn from others, but it does not get involved in a lawsuit: "Our car did not have any patent issues, we have a patent covering all the changes over, the change of an article. We did extensive use of someone else's non - patented technology, but the combination of integration of non-patented technology is our innovation. intellectual property rights should be respected, but it can circumvent. "

In the broken patent barriers, the BYD There are many clever ways, "say the appearance of the patent there were five car photos, front, back, side, are the top and oblique at the top, in these five areas are very similar, you may infringement, but as long as there is a photograph of which is completely different styles, even if the rest are not exactly the same dell Latitude D830 battery infringement. we head for a tail for no one who has a patent. "No wonder many people often have questions about why the face of domestic cars all grow well, while the bottom is very ugly? The original face is someone else's, only their own bottom.

Simplify Li + Battery Charger CC-CV Charging Test (b)

Select the battery model of the load

We first discuss the two must be considered, but eventually gave up modeling method. One of the ways the battery dell laptop battery load modeling are: the use of a source out (discharge) and inhalation (charge) current capacity of the battery voltage source and internal resistance of the resistor in series. As the Li + batteries require precise control of the termination voltage and charge current, present, all Li + battery charger is actually regulated power supply converters.

In addition, regulated power supply converter (charger) depends on the stability of the load (battery) the dynamic characteristics, we must select a model very similar to the load. Otherwise, the test can only verify that the VI characteristics of its own charger.

If only a one-off test, you can use the shunt regulator and resistor in series, This is enough to simulate the battery internal resistance, and, this simple cell model for fully meet test requirements. Advantage of this approach is powered by the charger itself. However, Laptop Battery a more rigorous testing needs of more accurate models. The model uses internal voltage source, voltage value is the process of charging the battery supply, a function of the total charge.

With the constant current source to charge the battery when the voltage will continue to change to a certain increase in positive slope. This is due to the internal battery discharge and other chemical changes in the process, accumulate around the cathode polarization of ions gradually reduced. Therefore, the operating point depends on the battery charger to connect the length of time, and the battery work history. Most E-Lab can be found using common components to build the load, to simulate the load of this complex model is difficult.

Require frequent testing of the charging circuit, or circuit characteristics must be described in detail, accurate simulation of the process of charging the battery dell Inspiron 2000 battery is very useful. Simulation process requires continuous scanning of all dc operating point charger. Analog circuits but also display the results, so that the operator can identify the problems and failures and interference. If the analog circuit can provide the battery voltage output and signal, these results can be directly as the oscilloscope signal. Testing can be speeded up (from hours to tens of seconds), and can be repeated many times as needed, than with a real battery test more convenient. However, after accelerated testing to determine the thermal effect of the negative charging power supply. Therefore, the test may require additional time to work with rechargeable power supply and adjust the thermal time constant of the circuit coincide.

The establishment of the battery model of the load

Figure 2 circuit simulation is the single-cell lithium-ion batteries. CC Stage charger termination charge voltage and fast charge current from the charger setting. Simulator is initialized, it can set the internal battery fully discharge voltage under the conditions of 3V,dell W0465 battery but the voltage can be raised to 4.3V, in order to test the situation before charging. 3V initial value is typically used low-battery voltage shutdown circuit (used to terminate the lithium-ion battery discharge process). This design specifically for the termination of charging voltage for the 4.2V standard CC-CV lithium-ion battery charger. The design of adjustment is very easy to adapt to non-standard termination voltage and fully discharge voltage tests. Test charger up to 3A charge current drive emulation circuit, by the power transistor power limit. Figure 2 circuit to simulate the increase in battery voltage, battery voltage is from a simulation of the circuit is set to begin fully discharged state, the circuit charging current function.

Figure 2 a single Li + battery case simulation circuit, the circuit can not use the actual situation of the battery to test Li + Battery Charger

According to the figure given in the parameter values, the charge current is 1A, the integration time constant of the analog circuits within 6-7 seconds dell Latitude X300 battery to reach 4.2V charger restrictions. On the current range, resistance, charge termination voltage and discharge voltage of the simulation is complete in the lithium-ion battery (in this case middle finger Sony US18650G3) typically done on the basis of the parameters. The simulation of the battery voltage without considering the impact of ambient temperature.

Shunt regulator design uses a MAX8515 shunt regulator and a pair of bipolar power transistor (select the regulator to take into account its internal reference voltage accuracy), high current TIP35 transistor installed in the radiator to dissipate 25W of heat on.

MAX4163 dual op amp which an amplifier is used to charge current integration, and the other amplifier on the current measurement signal amplification and bias. The op-amp has a high power supply rejection ratio, and supports full-swing input / output range of the two functions to simplify dell BAT3151L8 battery the circuit design. Note that, with the battery positive terminal emulator 0.100Ω current-sense resistor in series as well as the battery internal resistance.

In the automatic testing - data acquisition functions within the system work, can be an external signal to reset the simulation of the battery to fully discharge state. In addition, the manual operation test settings, reset button can be used.

The use of single-pole single-throw switch can choose two kinds of simulation of battery operation. To throw A-side, the realization of integral charge emulator, as described above. Throw B-side, the simulator will be set at a fixed dc operating point of the charger on-site testing of the output voltage and current smoking. To achieve this functionality, "Settings" voltage by changing the 50kΩ variable resistor, in the manual adjustment of between 2.75V to 5.75V. These settings are voltage internal inhaled current. The measured voltage terminal emulator (VBATT) is equal to set the voltage current flowing through the simulation cell with suction resistance (0.100Ω resistance) produced by pressure drop. Simulation circuit when the power from the battery charger dell 1G222 battery output.

Simulation of circuit performance

Figure 3 for the simulation of lithium-ion batteries to a 4.2V waveforms obtained in a typical VI. As can be seen from Figure 2 in the testing process: an initial fast charge current is 1A Charge (curve B and D), the other is a 2A fast charge current charge (curve A and C). In both cases, the first phase into the CC charge until the battery voltage reaches the termination voltage of 4.2V. After that, the current exponential decay, while the simulation of the battery voltage remains unchanged. Charge current is 2A, the time required to reach the termination voltage is shorter, and is expected to design the same. However, please note, the current double charging time does not make half will only make the time to reach half the CV mode, the battery load test with the real case.

Figure 3 according to Figure 2 battery simulation circuits dell INSPIRON 2650 battery draw graphics, fast charging waveform showed that the two conditions, the battery charger work, namely: CC phase 1A (curves B and D) and 2A (curves A and C) Charge Current

Figure 4 is set for two different voltages: 3V and 4.1V when the VI curve of absorption current. Two curves of dynamic resistance (indicated by the slope) is only simulated by the battery internal resistance 0.100Ω resistance.

Conclusion

As the lithium-ion battery charging process takes one hour or longer, using the actual load test lithium battery charger would be very time-consuming and often impractical. In order to speed up the battery charger testing, this article describes a simple circuit, used to simulate the lithium-ion battery. The circuit provides a non-use of the actual battery lithium battery dell INSPIRON 2600 battery charger to test effective means of

Simplify Li + Battery Charger CC-CV Charging Test (a)

2009-11-27T23:52:00.001-08:00

Simplify Li + Battery Charger CC-CV Charging Test (a)

Lithium-ion (Li +) cells compared with other chemical types of batteries Laptop Battery to be more vulnerable, for illegal operations with very small tolerance. Therefore, the lithium battery charging circuit more complex and demanding high-accuracy current and voltage settings. If you can not meet these accuracy requirements, the battery charger may not be completely filled, thus reducing battery life or affect battery performance.

In view of the Li + battery charger these requirements, the design of the charger completely tested and working within the framework of the entire sub-test is very important. However, the conventional load (ie, Li + battery) test Li + Battery Charger will be very time-consuming, but also in the laboratory and production environment is also difficult to achieve. To simplify the testing process, this paper presents a battery simulation circuits, can speed up the test speed, and without the battery case with the actual realization of lithium-ion battery dell Inspiron 1520 battery charger test.

CC-CV charge

Lithium-ion battery charging process of the first phase of moderate accuracy of the constant current (CC) charging, and then in the second phase of the transition to high-precision constant voltage (CV) charging.

Figure 1 for use in lithium-ion battery charger CC-CV IC (MAX1737) of the VI characteristic curve. This type of IC is the consumer products of all lithium-ion battery charger core. Figure can be clearly seen CC (2.6V to 4.2V battery voltage) and CV (4.2V) area.

Figure 1. MAX1737's VI curve is the standard Li + battery charger characteristic curves

Battery falls below 2.6V, the need to adopt a different charging technology dell laptop battery. If you attempt to discharge to 2.6V below the battery, charger required to provide a lower charge current ( "conditioning current"), will charge the battery voltage to 2.6V. This is the lithium-ion battery over-discharge must be taken when the security mechanism. VBATT <2.6V, by force if fast charging, would short-circuit the battery into an unrecoverable state.

CC to CV transition point of the critical phase of the tolerance of ± 40mV. The reason why such a demanding tolerance, because if the CV is too low, the battery will not be completely filled; while CV is too high, it will shorten the battery life. Means to detect the termination of charging the battery to reach full capacity, the charger must be disconnected or shut down. In the CV stage, when the detected charging current to quickly charge or maximum charge current flow of a certain percentage (usually "10%) when the termination charge.

Li + Battery Charger Parametric Test

Li + Battery Charger design usually consists of two basic parts: the digital part (control state machine) and analog parts, including those with high-precision dell 4834T battery analog part ( "1%) benchmark, can be precisely controlled current / voltage source. Pairs of lithium-ion battery charger (not only refers to IC) completely testing is a very difficult and time-consuming work, not just limited to current or voltage value tested.

Test, should be carried out throughout the scope of work of the charger segmented detection: including CC stage, the switch from CC to CV, charge termination. As noted above, the ideal test is the load on conventional charger: the Li + battery. However, due to charging process takes one hour or even longer, the use of lithium batteries is very time-consuming testing. Depending on the different test conditions: for example, large-capacity rechargeable battery + slow, small-capacity battery + Fast Charge as well as other possible combinations, the test time is not the same.

In addition, the charging process can not guarantee dell 2834T battery not to damage the battery under the premise of increased charge current, because the battery charge current by the maximum charge rate (ie, fast-charge current) constraints. For consumer products commonly used in batteries, very few provisions of current is greater than 1C (in 1 hour the battery fully discharge current). Therefore, in most cases to complete the charge cycle, the time required often exceeds two hours. If you need to repeat the test, you need to fully discharge the battery - this process is only slightly shorter than the charge. Or, must be able to have fully discharged the battery at any time.

Also you can use a simulated ideal alternative to a true load battery load test. Simulation should verify the circuit's DC response and dynamic stability. However, the use of power measurement standards used in simulation of the load to the battery is very difficult. Unlike most power supplies used in load testing is different from the battery can not be simply treated as a fixed resistance or exposure to current. As noted above, the scope of work must be carried out within the entire sub-tests. The following description of the Li + battery charger test circuit fully meet these dell Latitude LS battery requirements.

How do I just bought a new laptop battery charger

How do I just bought a new laptop battery charger

The use of lithium batteries should be noted that a period of time after the battery Laptop Battery is placed into hibernation, lower than normal capacity at this time, use of time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycles the battery can be activated to restore to normal capacity. As the lithium battery's own characteristics, its decision is almost no memory effect. Mobile phones so users of the new lithium battery in the activation process does not require special methods and equipment. Not only the theory that, from my own practice point of view, from the outset on the use of standard method of charging that "activation" approach is the best.

For the lithium battery "activate" problem, many say is: recharge time must be more than 12 hours, repeated three times to do in order to activate the battery. This "The first three charging more than 12 hours to charge" was obviously from the nickel battery (such as nickel cadmium and nickel metal hydride) inherited from the argument. Therefore, this argument can be said that a beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics are very big difference, but also very clear to tell you that I have gone through all the serious official stressed that technical information and charge-off will discharge lithium batteries, especially lithium liquid ion battery causing great harm. Accordance with the standard charge and therefore the best time and the standard method of charging, in particular, not to carry out more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of Hp 398876-001 battery charging.

In addition, lithium batteries cell phone or the charger will automatically stop after the battery is full charge, there is no electricity nickel charger for 10 hours of the so-called "trickle" charge. In other words, if your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change and the quality of fail-safe, so your battery will be a long-term at the brink of danger. This is also another charge against the chief reason.

In addition, in some mobile phones, charging more than a certain time, if they do not remove the charger, this time not only to stop charging system will start to discharge - charge cycle. Perhaps the makers of this approach has its own purpose, it is clear that the battery and cell phone / charger is detrimental in terms of life expectancy. At the same time, long charging would take a long time, often at night, but to our power grid situation, at night in many places higher than the voltage, but also volatile. As already said, the lithium batteries is very precious, and it more than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this Hp PB992A battery brings additional risk.

In addition, another aspect can not be ignored is the lithium battery is also not suitable for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following questions.

2, normal use should be when to start charging

In our forums, often see this argument, because the number of charging and discharging is limited, so phone the battery should be used up as much as possible recharge. But I found one on the lithium-ion battery charge and discharge cycle test table, on the cycle life data is as follows:

Cycle life (10% DOD):> 1000 times

Cycle life (100% DOD):> 200 times

DOD is the depth of discharge in which the English abbreviation. Can be seen from the table may be the depth of charge and discharge times, 10% DOD cycle life than when the 100% DOD for much longer. Of course, if the actual charge equivalent to the relative total capacity: 10% * 1000 = 100,100% * 200 = 200, the latter a full charge and discharge, or better than some, but in front of friends do say that some of the amendments: Under normal case, you should have a reserve battery power is left in accordance with the principle of charging run out of charge again, but if your battery in your first two days can not be expected to persist throughout the day, when they should start on time charge, of course, if you are willing to back the charger to the office again a different matter.

And you need to recharge in order to cope with the anticipated upcoming busy communications will lead to an important event, even though there are a lot of battery Hp PB994A battery power over time, then you just charge ahead, because you are not really lost, "a" sub-charge cycle life , that is, "0.x" times only, and often this x will be very small.

Run out of battery power and then filling the remainder of the principle is not want you to go to the extreme. And long, like charging a widespread view that "as far as possible the cell phone battery power runs out, it is best to use automatic shutdown." This is really just practice on nickel batteries, The purpose is to avoid the memory effect occurs, unfortunately, it is also spread of lithium batteries on this. It has been too low because the cell phone battery warning appears, still do not charge to continue to use the example has been used in automatic shutdown. The results in this case, cell phone charging and starting later in the no response, had to give customer service overhaul. In fact, this is because of the battery caused by excessive electrical discharges in low voltage, so that does not have the normal charge and the boot and conditions.

3, for lithium batteries cell phones right way

To sum up, I lithium batteries used in mobile phone charging and discharging, the most important tips are:

1, in accordance with standards and procedures, charging time, even the first three have to do so;

2, When the phone prompts when electricity is too low, we should try to begin charging a timely manner;

3, lithium batteries Hp PB991A battery do not need to activate the special method, in a normal cell phone use lithium batteries will naturally activated. If you insist on spreading the use of "the three previous 12-hour long activation charge" approach, in fact there will be no effect.

Therefore, all the pursuit of super-long 12-hour rechargeable lithium battery cell phone use and the integration of the practice of automatic shutdown, are wrong. If you have previously done in accordance with the wrong argument, please correct in time, perhaps not too late.

Of course, cell phones and chargers to protect themselves and control circuit of good quality cases, the protection of lithium batteries is still quite guaranteed. Therefore, the charge is the focus of understanding of the rules, and in some cases also may make some concessions. For example you find in your cell phone the night before bed charge, you can also start charging before going to bed. Crux of the Sony PCGA-BP1N battery problem, you should know what the right thing, and do not deliberately wrong to do so in accordance with.

Battery Application Maintenance Guide books

Compared with desktop and notebook than the good of the greatest advantage of mobile Laptop Battery portability, which with notebook in the application of an integral rechargeable battery. Rechargeable battery a great convenience for notebook use in complex environments, whether in traveling or in a coffee shop, one Taiwan "unplugged" notebook computers have become the most beautiful landscape. In fact since the inception of notebook computers, manufacturers have not stopped the development of laptop batteries and upgrades, from the initial use of nickel-cadmium batteries (NiCd) batteries to Nickel Metal Hydride (NiMH), and then to the widely used lithium-ion battery (Li -Ion), laptop battery has experienced long-term escalation of the revolution. At the same time, increased battery capacity in the best possible circumstances, the notebook hardware manufacturers also focus on the development of energy-saving products, such as low-power processor, SSD hard drives, LED backlit screen applications such as laptop machine are effectively reducing the power consumption, The purpose of doing so, environmental protection, the more important is to give users a longer notebook battery Hp HSTNN-DB20 battery life.

Long-lasting power station notebook

However, the laptop battery life and the use of time, or let the user afflicted. Often do not use the notebook unplugged friends is not difficult to find, with the use of time increases, the notebook battery capacity seems to become smaller and smaller, and the original can be used three hours, and now only 2 hours is necessary to stop clamoring; some friends in to buy business notebook was told the battery can be used 6 hours (or more), while the use of only carried out when we got there, even browse the Web, edit documents some simple operation, battery life is still hovering around the 2-3 hours, is being profiteers blinded or because incorrect use?

Notebook lithium batteries

For these problems, we built-in lithium-ion battery Hp 395789-001 battery from the notebook's basic structure, and users will encounter in use some common problems, we should explain how the proper use and maintenance of lithium-ion battery, so that your beloved The notebook was a motivated mobile power stations.

As mentioned earlier, the vast majority of notebooks currently on the market adoption of lithium-ion batteries, lithium-ion battery from the pen casing, circuit boards and batteries composed of three parts. In the case apart, we will see a section similar to ordinary dry battery power-saving core, but in fact the chemical composition and batteries all have very different sizes, storage capacity for non-regular battery can hold a candle to.

Lithium-ion battery chart

Lithium-ion battery is characterized by large capacity, light weight, the memory effect of nickel-cadmium batteries are also far less obvious. In the evaluation and introductory Hp 396008-001 battery article, we often see the "x-cell battery", "mAh" and other words, the so-called core cells of several "core" refers to the number of batteries within the battery, at present there are three main laptop battery core, 4 core, 6-cell, 9-pin and 12-core, mainstream notebooks on the market more than standard 6-cell battery life is generally 3 hours or so, pay attention to what we call "life" is not equivalent to "standby time" , users must purchase the rhetoric of rational business judgments. A higher demand for mobile office users can buy large-capacity 9-pin and 12-cell battery, of course, a number of relatively expensive price, we will increase the weight of laptops.

The internal structure of the battery

mAh value determines the battery Hp Pavilion dv9000 battery(Hp dv9000 battery) standby time, mAh value is higher the longer the battery usage time. We usually say battery life is determined by the number of battery charge and discharge decisions, the general lithium-ion battery charge and discharge times for the 500 or so, but not the charge will be included in each account, the charge will be counted as more than 80%一次. As a general user's need for frequent recharging, laptop battery life in 2 years or so, and then it would rapidly aging, standby time greatly reduced, which is almost all notebook warranty regulations, will the battery warranty period is set to 1 or so, the reasons for .

Lithium-ion batteries are very sensitive to temperature, the ideal temperature is 20-30 degrees Celsius, when the temperature is below 6 degrees Celsius, lithium-ion (Li-ion) batteries will self-discharge of 5% per month, which is the best Save mode, but if when the temperature dropped to zero degrees Celsius, the original battery capacity will be reduced to 80%, when the temperature at minus 10 degrees, the capacity dropped to 50%, when the temperature dropped to a certain extent, lithium-ion battery Hp EV087AA battery there is a total loss risk.

Hot environments

Cold environments

Since I can not tolerate low temperatures, then the lithium-ion batteries in high-temperature environment, what is done? Based on case studies and more than proved that under high temperature lithium-ion batteries will greatly shorten the life span and may even be an explosion.

Laptop Cooling Base

In daily use laptops to pay attention to body temperature, the temperature is too low as far as possible not to use the environment, while also note that body heat, it is recommended by means of cooling pad for notebook cooling time, so not only can extend battery life, other internal components of the notebook is also good for life.

In addition to purchasing large-capacity battery Hp EX942AA battery , by setting the power-saving mode, adhere to a correct way to use is to extend the battery usage time effective way. First, we screen and graphics by adjusting the operating mode to reduce power consumption machine. Large-screen notebook power consumption, the general will Laptop screen brightness set to grades 6-10, who are able to be around 50% brightness, but when used at night to about 30% of brightness has been completely sufficient. We know that an independent graphics to provide better high-definition decoding, providing users a clearer lifelike video entertainment experience, but power consumption is relatively high, if your notebook is equipped with dual-graphics and supports graphics switching, it is recommended in the absence of the case of an external power supply is set to separate the use of integrated graphics, although the results will be discounted high-definition, but it can be extended endurance time was 20-35 minutes.

Set standby mode

Second, temporarily using a laptop computer, you can put the computer into standby. We usually will set the power options will be closed roof of the relevant directives set to auto-standby. Specifically, in Windows "Control Panel" and select "Power Management Properties" dialog box, enter the "Advanced" option, the "power button" is set to close the portable computer, "standby", so that can be very convenient to reduce the laptop when not in use at the moment the electricity consumption, thereby extending the use of time, of course, different versions of the operating system settings in the way there will be nuances.

Unplug peripherals can also be energy-saving

In addition, the external device will increase the machine Hp Pavilion ZT3000 battery power consumption, is therefore proposed that the mouse, U disk, memory card and other external equipment, disconnect and turn off the wireless network adapter, infrared port and Bluetooth, and even reduce the processor's operating frequency, these are In exceptional circumstances the necessary means to extend battery life.

We have mentioned earlier, the battery life is the decision by the battery charge and discharge times, the constant charging and discharging operations, will accelerate the aging of the battery is damaged, so how to properly charge and discharge will become a key element to extend battery life. Many consumers purchase notebook computers will be told to charge and discharge completely three times, in fact, even in everyday use, we should try to ensure the power run out after filling. The first application with the notebook compared to nickel-cadmium batteries, lithium battery memory effect, while not obvious, but still does exist, but a full charge and discharge is the best way to avoid the memory effect.

Complete charge and discharge will help extend battery life

Most laptop battery at full power, full power, the battery charging circuit within the state is still open, so there is an external band of energy, it is recommended not to use the battery as far as possible, not with the battery in the case of multiple plug an external power supply, because power relatively abundant, each time an external power supply plug on the equivalent of charging time, is the same as the laptop battery in the aging step forward has been on the road.

Charge should also be cautious

The battery discharge must comply with certain preservation rules, lithium-ion battery deep discharge more serious consequences may result severe battery failure or total loss, and thus the battery store about three months later, it is recommended the battery Hp 337607-001 battery out to re-charge the battery in order to avoid excessive self-discharge.

Described above, are the daily use of laptop battery standard, while the last two years, many consumers have been repeatedly exposed laptop battery explosion, spontaneous combustion and recalls the incident shock, lithium batteries have a panic fear of the psychological. In fact the battery explosion happened probability is very low, annual shipments of notebook batteries in the millions around the probability of the occurrence of explosion is almost equivalent to buying lottery tickets in the first color, and in the bombings, there is partly due to users caused by improper.

Laptop Battery Explosion

Laptop battery ignition

Triggered laptop battery cause of the explosion, in addition to the circuit the battery outside of its own heat and humidity are mainly two points, how to cool the notebook we have already talked about the need to pay attention to is never in the wet environment using a laptop, although some of The so-called "three defenses" product known as waterproof, but generally refers to the set up between the keyboard and the internal components of a sealed compartment, blocking the liquid from the keyboard into the laptop internal gap in-depth, while the laptop battery is not part of the defense capability of liquid .

To protect books from damp

Then the liquid or moist environment on the laptop battery, what damage? In the humid environment, the laptop battery is prone to short-circuit the internal Hp 337607-003 battery circuitry, causing the circuit failure is likely to directly harm notebook, or cause the battery self-ignition and explosion. However, users do not need to worry too much, as long as the guarantee not to use high temperature and high humidity environment, notebook, stick to the correct battery usage, the battery is basically the probability of explosion could be ignored.

To get rid of a bomb hidden battery

To get rid of a bomb hidden battery

Consumers spent to purchase high-priced but has a hidden Laptop Battery explosive issue of the battery, which the user is concerned, we can not accept the fact. But such events do occur, the problem of the existence of the battery is indeed the major people scared ... ... According to media reports, the U.S. Consumer Product Safety Commission has disclosed for the HP and Compaq notebook computer lithium-ion battery packs may overheat, triggering fire, causing property losses of the user, therefore, Hewlett-Packard decided to recall tens of thousands of blocks of the problem batteries. It is understood that this is already the second time within six months, HP's implementation of the notebook computer lithium-ion battery recall program areas.

Hewlett-Packard has taken the initiative to recall the batteries, first, in order to ensure customer safety, also embodies the two responsible for HP's customer service attitude. However, "why the battery safety issues often happen?" A lot of consumers shocked by the issue of doubt. As the popularity of modern life, consumer electronics, the battery Hp 338794-001 battery had to rise to reflect on the problems exposed. As consumers themselves, how to prevent and reduce the risks to happen?

Occurrence frequency of the battery caught fire and exploded, triggering fears

Strong global demand for consumer electronics, lithium battery industry has stimulated the development of new security risks also will be increased. It seems every other period of time, there will be a brand recall of notebook computer laptop batteries, regardless of former Dell, Sony, or HP ... ... today's laptop batteries, cell phone batteries and other civil battery safety issues more and more affected by people's concern.

The Hewlett-Packard has taken the initiative to recall the batteries in the industry is not the first time, and certainly not the only one. In 2008, 100,000 used the Sony laptop batteries recalled; the same year in August, Dell announced the company's headquarters Hp PP2182L battery worldwide recall of approximately 4.1 million "fires" batteries, these batteries under extreme conditions in a particular , due to a number of battery cells in the presence of metal particles, the battery overheating and even fire risk will increase, this is the history of the consumer electronics industry, the largest single recall. Security risks exist not only laptop battery, mobile phone battery explosion case is also frequent, threatening people's lives and health.

Therefore, from a few years ago, sporadic incidents of security risks, to now come and go, the "explosion" sound, laptop batteries, cell phone battery safety issues seem to have reached the point of imminent. But in China, neither the battery of national standards, the lack of corresponding recall mechanism, which also makes the battery crisis, but not fundamentally solved repeatedly performed. Shows that consumer concerns are justified.

Alert! Cottage battery may be close, "Grenades"

In addition to original equipment batteries currently on the market, there are professional battery manufacturers to produce batteries, as well as the Hp 345027-001 battery cottage batteries to choose from than the original offer price of most of many. However, consumers best buy original batteries, because the vast majority of non-original battery is not charging protection, it is prone to overheating, the most serious is the cause spontaneous combustion and explosion. In particular, the so-called test battery cottage is completely unqualified.

Early in Guangzhou a man hanging in the chest cell phone suddenly exploded, resulting in excessive bleeding death; Subsequently, Hunan, an 8-year-old girl injured his left hand was mobile phone batteries, due to his injuries, the palm can not be restored, only amputation; Earlier, Gansu Jinta County Camp Hongyun Mining Development Corporation when operating a welder in the workshop, but also due to uniform jacket pocket mounted on the mobile phone battery exploded, resulting in the death scenes ... ... the cause of this bloody Hp 342661-001 battery case the culprit is cottage battery.

In addition, according to insiders, in order to interest a lot of cottage electronic products are "super-long standby battery can be" and the low price and some other false reasons and unfair competition to attract consumers. Cottage mobile phone batteries are commonly used in low-quality materials, such as shell material, the regular use of aluminum manufacturers, while the cottage aircraft battery shell material is usually iron, no good electrical protection, are explosive. Cottage battery is a high-risk products!

A multi-pronged preventive measures

No one wants to carry one all day "time bomb", this, the industry to remind consumers: best not to yield to the temptation to buy cheaper so-called "parallel imports", "cottage machine", it is best to purchase the brand authorized dealer licensed products . In addition, chargers, batteries and other Hp pavilion dv6000 battery(Hp dv6000 battery) accessories must use original product. Not only the quality could be assured, and the security is much higher.

At the same time, this recall to replace HP's plans to encourage users to check all random sold or purchased as a spare parts battery, involving the product model, Chinese users can visit the HP Web site to learn more. For such cases, consumers should promptly follow-up to understand, for to purchase products should have the courage to come forward to safeguard their legitimate rights and interests.

It is noteworthy that apart from their own quality of laptop battery problems will cause an explosion, the consumers themselves may also occur improper use of the same battery safety accident, so operating laptop computer, should avoid the following situations in order to reduce security risks, extending Battery life: full of it still draw a line power source; uninterruptible power supply on the bed; a long time do not use batteries; often the battery removed, exposed the battery Hp Pavilion dv8000 battery(Hp dv8000 battery) position. When the battery make sure that the demolition dust waterproof moisture shock on a regular basis with a small brush clean.

Today, one side is becoming increasingly popular notebook computer, while there are security risks because of their batteries and allow consumers to feel fear, say that this is a sad thing. To eliminate the repeated shouts of "explosion" sound, crossed the "terror zone", in addition to relevant institutions, industries, businesses work together, consumers have self-protection to eliminate hidden dangers, it will no longer cry, "always hurt me" .

Of new energy dilemma energy structure to be solved

The recent heavy snow so that natural gas demand throughout Laptop Battery the surge, while the supply side, said every effort had been still can not meet the demand, which leads to many parts of the country a "gas shortage" in some cities the gap even up to 40%.

Like encounter "power shortage", "Oil Shortage", as this explanation of "gas shortage" causes are: extreme weather events leading to the demand surge, resulting in short supply. However, in the contradiction between supply and demand behind it reflects the one-time resource bottleneck. Grid can be built, wells can play, the trachea can shop, but it is a one-time non-renewable resources. If the gas exhausted, and the trachea shop had to pay a long, what for?

Of natural gas because of its low-cost, clean, environmentally friendly features have been a lot of promoting the use of, but as a primary energy dell 312-0625 battery, natural gas reserves are limited. At present, natural gas, more than 400 billion cubic meters of annual output is only about China's energy production in less than 5%. Data show that China's total gas reserves of natural gas in the world in less than 3%.

This, the authorities urged the public should be saving gas. Of course, energy-saving responsibility, but both require the production or the life of the use of energy, so the use of energy, in addition to reducing expenditure have to open source.

To seek resources abroad is one way to succeed. In recent years, China actively with the countries in the world to carry out oil and gas cooperation, from Saudi Arabia, Russia to Venezuela and Brazil, China Petroleum, Sinopec to learn the world's oil pipelines, are from the Middle East to North Asia, dell 0XR693 battery South America extended.

"However, only a simple response to the issue of energy imports to rely on other countries is not a fundamental way. For the most populous country like China, the world in any one country can not provide adequate supply. In the final analysis, to solve the energy crisis have to rely on myself." Executive Dean of Institute of World Energy Finance, China Financial Research Institute, said Mr Ho Sai-Hung, China's conventional energy resources is only 60% of the world's average, in order to meet growing energy needs, we must accelerate the development and utilization of new energy, which is to solve the problem the key.

Wind resources in China is rich in wind energy development and utilization of available reserves of 10 million kilowatts. At the same time, has a very rich solar energy resources in the Northeast, Midwest, North China are large amount of solar radiation. And in the geothermal field, according to estimates, China's major sedimentary basin geothermal energy stored in dell XR693 battery 736 Yiyi Qian J, exploitable geothermal resources in the country amounted to 6.8 billion cubic meters annually, equivalent to 32.84 million tons of standard coal each year generating capacity.

Not long ago, Obama said during his visit, the two sides agreed to strengthen the clean air, water, transport, power and resource protection cooperation and signed a "China Science and Technology, National Energy Bureau and the U.S. Department of Energy on the Clean Energy Research Center of China-US Joint Protocol on Cooperation, "the future of the two sides will invest at least 150 million U.S. dollars for clean energy research.

In fact, new energy development and utilization of our country dell RN873 battery there are still insufficient. According to the National Energy Board data show that in 2008 China's primary energy consumption, composition, coal will still account for 69% of the proportion of wind power, solar, nuclear and other new energy sources share of less than 2%.

"The new energy in the whole society negligible amount, which is non-fossil energy sources by 2020, accounting for the proportion of primary energy consumption reached about 15% of the target is still a considerable distance." Li Junfeng, deputy director of NDRC Energy Research Institute, said, "The new energy industry also need to give government and community dell GW240 battery understanding and support. "

China Renewable Energy Society for Shi Dinghuan that the new energy capacity to adjust to play the basic role of market regulation, while strengthening the government's macroeconomic regulation and control. Government needs to help companies build technology research and development platform that supports R & D and production and research integration and to develop new energy future, large-scale development can adapt to a variety of technical and management Dell HP297 battery personnel.

2013 solar panels will double the market share of thin film technology

2009-11-19T04:43:00.005-08:00

2013 solar panels will double the market share of thin film technology

According to iSuppli Corporation, thin-film solar cells are rapidly capture Laptop Battery market share in crystal technology have been, to 2013, the PV part of more than double the number of watts. By 2013, solar panels in the global market, the efficiency of thin film from 2008 of 14% to 31%.

"FirstSolar already showing strong evidence of the viability of thin-film market, the company jumped this year, the world's largest manufacturer of solar panels, yield more than one billion watts." ISuppli's research director GregSheppard said, "At the same time, the company has already produced per watt the cost down to less than 90 cents a silicon crystal is about half of the module manufacturer. "

Crystal and thin-film

Most solar panels made from crystalline silicon, using 180-230 micron polysilicon. On the contrary, thin-film panels through the deposition of multi-layer Hp Omnibook XT1500 battery substrate made of other materials, the thickness of a few microns. The main difference between the two technologies lies in the efficiency and cost of electricity per watt. Thin-film panel in the sunlight into electricity less efficient, but its production costs are significantly lower.

It is noteworthy that the film in the installation space is limited at a disadvantage, such as residential roofing. Film installation may need more space to account for 15-40% of the crystalline silicon to achieve the same with the overall system power output. This tends to limit its activities in certain application areas more attractive.

Price comparison

Thin-film modules are expected next year, the Hp Omnibook XT1000 battery average price will drop to 1.40 U.S. dollars, 1.70 dollars lower than in 2009. In 2010 the average price of crystalline silicon panels are expected to fall to 2.00 dollars, 2.50 U.S. dollars this year.

iSuppli Corporation predicts that by 2012, crystalline silicon will to a certain extent, to narrow the price gap, because its suppliers are financially strong, they continue in capital expenditures, technology development and has invested heavily in improving production processes.

iSuppli, the global thin-film solar cell production, and crystal technology, the proportion of forecasts.

Variety of thin film technology

There are a variety of thin-film photovoltaic technology. They are mostly less than 10% efficiency, although some technology can be Hp Pavilion ZT1100 battery efficient through experiments up to the middle class. Some of these technologies are referred to as a single node, using a diode. Recent developments in the use of multiple nodes with each other superimposed together, also known as tandem and three knots, so by using different materials or combinations wider absorption spectrum of knot.

Most of these techniques rely on chemical vapor deposition (CVD), or derived from the screen printing process, the layers of material deposited on different substrates, namely glass and various plastics. Some of the recent use of inkjet printing technology, like ways to more quickly deposited materials.

Promote the accelerated development of thin film technology, another factor is the use of materials,Hp Pavilion XZ200 battery companies such as Oerlikon, and to provide more Centrotherm package production lines.

South Korean experts to develop a new material to enhance the safety of lithium

According to foreign media reports, South Korea's engineers developed a lithium-ion batteries Hp OmniBook 6000 battery used in isolation within the new material, can more effectively resist high temperatures and external influences, so that laptops, cell phones and other electronic devices use lithium-ion batteries safer.

It is reported that South Korean Atomic Energy Research Institute engineers developed this new material can resist temperatures of 150 degrees Celsius. Lithium-ion battery materials within the traditional isolation of porous polyethylene, can be easily cathode to the anode of lithium-ion free and produce electricity. In the heat or external influence, such a porous polyethylene material Hp F2019B battery but can also act as an electrical insulator function.

Schematic diagram of the internal structure of lithium-ion battery

The isolation of a newly developed composite material is polyethylene, fusion of polyethylene, nano-alumina and bran powder agent. Testing shows that the isolation material can act as electrical insulators, even in 150-degree heat and external tremendous impact, Hp F2019A battery we also can play a role in insulation. South Korean engineers said that this isolation technique has been applied for two new patents.

Notebook computer more secure

South Korea supplied 30% of the world's lithium-ion battery, the size of the domestic market in 2010 is expected to 3,500 billion won in the global market size expected to be 1 trillion won. If this new separation technology could be used in lithium-ion batteries, in fact, profits can be Hp F2019 battery foreseen.

Lithium power industry face many problems

2009-11-19T04:43:00.001-08:00

Lithium power industry face many problems

Influx of a large number of enterprises, but it is followed by a rapid decline in profit margins, in a few short Laptop Battery years, the lithium industry, profits have been 100% of the profits from the previous reduced to 5% of the low-profit.

At present, there are hundreds of manufacturing enterprises in Shenzhen, the country is concerned, should be more than 1000 of the. ZENG Zhi-ming told reporters that although the development of lithium power industry, just a few years, but the pace of development beyond imagination. Zhi-Ming Zeng worked in Beijing, Anwar Ibrahim on United Energy Technology Co., Ltd., has witnessed this emerging industry since its birth, then quickly dissolved into chaos after the development of the entire process.

Beijing Anwar United Technologies Corporation in the industry is also a relatively large enterprises, and claimed to be the best domestic technology iron phosphate battery production factories, the main development, manufacturing and marketing of new power rechargeable lithium iron batteries, lithium-ion rechargeable battery and its accessory products, widely used in electric Hp 346970-001 battery vehicles (EB / EV / HEV / PHEV), electric tools, solar, UPS, digital products, product export to Europe and North America.

Present, however, Beijing Hualian contract security industry, like the vast majority of businesses are in the common development of the industry feel the pain of confusion. Non-standard operation of these enterprises, directly led to a decline in product margins, at present only a small number of high-end enterprise customers due to stable and healthy development. ZENG Zhi-ming laments.

According to the industrial chain, lithium batteries into the battery product and battery materials, battery materials can be divided into cathode materials, anode materials, membranes and electrolytes. Lithium cobalt oxide, manganese oxide, lithium nickel cobalt Hp Omnibook XE3 battery manganese are of lithium and lithium iron phosphate cathode material for Li-ion battery technology, core; Zeyi graphite anode material, solid carbon particle-based; in positive and negative middle electrolyte and diaphragm.

The status quo is both a lithium battery manufacturers and battery materials manufacturer, has technical advantages of the enterprises are very few.

"The main problem the industry is not competitive and disorder problems, the most critical issue is price and technology." Frost & Sullivan research institutions focused on the new energy sector analyst Linda told reporters that the United States, Japan and other than any other country, China's lithium battery industry, the technology gap is obvious.

It is understood that companies around the world have also strengthened their research and application of lithium batteries, but lithium batteries and other high-current explosive issues remained unresolved, and the Chinese manufacturers in the level of the more backward in this regard. Li-ion battery industry has been concerned about the Hp F2024A battery development of wind investment industry, Chen Qiudong also noted the technical level of the industry problem of the poor.

Chenqiu Dong pointed out that domestic lithium iron phosphate material is also no a benchmarking company, each doing half a dozen of material properties are necessary to make the general level is not difficult, but to do this material (in particular, is to look at processing performance, stable nature as well as high rate discharge of sexual characteristics) is no easy matter.

According to statistics, China had Tianjin, Shandong, Zhejiang, China (Jiaxing, Huzhou, Jinhua) and other places several huge investment to do the battery maker Li-ion battery materials, the results will die a natural death, the main technical issues can not be resolved. Chenqiu Dong pointed out that with technology partners to find a great association. Many colleges and universities or research institutes, technology is only laboratory technology, a far cry from the industrial. Laboratories doing out of material properties are excellent, but in the pilot phase will encounter a lot of trouble, even if reluctantly passed the test pass, to the industrialized mass production stage, exposing the problem will be even greater. And, this is not an isolated phenomenon, but rather a common Hp F2024B battery phenomenon.

Linda pointed out that, in addition to technology, power lithium battery high prices impede its rapid market is a key factor.

"The main reason is the high price of output is small, there is no scale. If we can into the scale of production, sale, such costs would be quickly dropped."

Technology is the most critical factor in the development of enterprises. There is no mature technology, inevitably restrict the speed of development, if the stay in the laboratory techniques, or at least have to at least 2-3 years of exploration, technology and talent are Hp Omnibook XE battery inextricably linked Furthermore, after all, lithium iron phosphate material and battery technology has not yet fully mature, the industry has no uniform standard, equipment, raw materials, technology and other practical problems have to rely on people to resolve. Without a strong financial strength, even if the materials out of, the corresponding production or management can not keep up, they will lose opportunities for collaboration with large customers, the key technical personnel for the team motivation enough, will lead to the loss of human resources. Have no outstanding executive team, even the best technology does not produce value, here, includes the implementation of the so-called R & D, production management, Hp F1739A battery quality management, marketing, and other links, for start-up companies which are very challenging.

Hybrid electric vehicle batteries the biggest challenge is

2009-11-09T22:29:00.001-08:00

Hybrid electric vehicle batteries the biggest challenge is

Auto energy-saving emission reduction has become the driving force behind the Laptop Battery development of automotive electronics, with the increasing oil supply shortage and growing environmental pollution, electric vehicles such as electricity-powered vehicles, with its energy-saving and environmental protection advantages of becoming a concern to the industry focus. However, even if the electric car has many advantages, but it is a time can not replace the traditional gas powered model, so the new hybrid vehicle is clean electric vehicle with industrialization and marketization of the most promising models. However, batteries, cost, reliability, longevity, more complex environment, the requirements of high-voltage power devices for automotive manufacturers and many other issues facing the many challenges.

Infineon Technologies (China) Limited's automotive electronics business, senior marketing engineer Cao Yu pointed out: At present, the main challenges of hybrid cars from two aspects: one is the traditional power systems and electric systems of coordination; the other is the need for cost-controlled conditions, to meet the automotive electronics in complex application Hp EV088AA battery environments reliability requirements.

Cao Yu: Hybrid cars as a major challenge is the traditional power systems and electrical systems for coordination.

Fairchild, senior manager of global automotive market, Hans-PeterHoenes believes that hybrid vehicles the main design challenges are based on a very low cost to create a very complex and yet highly reliable systems.

"Electric cars can be divided into three categories: hybrid, fuel cell and electric vehicles. Electric car there is a universal problem - battery, batteries due to the existing problems, the future can be the possibility of mass production the largest is the hybrid. than a hybrid engine with conventional technology, an increase in three parts, one vehicle control, 2 battery management, and third is motor control. "Freescale's automotive electronics engineering manager for China Hp HSTNN-LB31 battery, said Kang Xiao Dun .

Kang Xiao Dun: The battery technology is the key to hybrid cars, batteries account for the cost of the vehicle 1 / 3 of the above.

Hybrid electric vehicle is further divided into light (micro) mixed with full hybrid vehicles, the challenges they face are different.

Light mixed with the different challenges facing the entire mixed

Cao Yu analyzed, micro-mixing system and the entire hybrid system in the system are structurally very different, it is more than the total electrical power system, the percentage of the value of difference is important that the quantitative changes in the structure caused by vehicles. Micro-hybrid system in general to achieve start-stop function, the whole hybrid system requires no engine power vehicles in the case still has some endurance. Because the system greatly increased the coupling degree, full-hybrid system structure is more complex and more challenges in Hp Pavilion dv2000 battery(Hp dv2000 battery) the design.

Hans-PeterHoenes were analyzed for the mild hybrid vehicles, the chassis (the basic design) is still the traditional automotive design, usually in a normal car on the integration of hybrid characteristics. As the chassis (the basic design) design has been set, the additional needs of all systems must be able to meet the demand. However, this is not always the best technical solution, so far the biggest challenge in this regard is the integration of mechanical and electrical integration. In other words, the minimum space requirements need to design. As for the full use of hybrid cars, the whole design needs to change, not only the powertrain, chassis and even had to move forward and is optimized for mixed. A good design should be designed around the automobile powertrain, while the traditional program is designed to cars, but the engine placed in the "somewhere." This is a complete change in the concept of Hp PP2200 battery design thinking, because drive system has been decided, or at least greatly affect the shape and appearance of the vehicle.

"Design work is facing the biggest challenge is the lack of high-power electric transmission under high pressure (high pressure-driven high-power motors) has extensive experience in automotive engineers. As a result of conditions and the traditional cars are different, so even in the field of industrial drives and experienced Senior consultant, can offer the help is very limited. "Hoenes said. Fairchild not only has a discrete power technology, as well as gate driver IC such as IC. This not only applies to low-voltage, but also covers the full voltage range of up to 1200V. This module integration capability allows customers to receive a fully tested to optimize power level, can solve many problems related to the interaction between the parasitic and device design issues.

Motor Control Challenges

In motor control, Cao Yu pointed out that the main difficulty is the need to achieve auto-level reliability requirements, and needs to take into account the cost of Hp pavillion zx5000 battery(Hp zx5000 battery) realization of the right. Also need to consider the high-power drive system caused by electromagnetic interference and noise effects. If you are using industrial-grade device although the initial period of no major problems, but as time goes on, accompanied by a device destined to produce failure, vendor will give the brand image and reputation has brought incalculable loss, "so we recommend the use of automotive-grade devices, can effectively guarantee the vehicle's life cycle system, reliable operation. "he said. "As the world's leading supplier of power devices, Infineon has a deep system of experience and many experts team, which can better understand the specific needs of customers, even helping customers find those hidden in the system application requirements under the details."

Infineon offers the industry's leading provider of high power density automotive-grade module HP1 (hybridpack1) HP2 (hybridpack2), with ultra-small size, the most relevant automotive systems of space limitations. HP1 weight 485g (72x140x17mm) 3 half-bridge in-one design, 650V400A maximum drive capability for less than 20-30KW motors. HP2 (106.5x48.5x20.5mm) weight of 1250g, is more directly based on a special water-cooled thermal design in order to meet the 80-100KW Module 650V800A motor applications.

Microchip Automotive Products Group Automotive Marketing Manager, Chan Chung-yan, the view that: "In the hybrid vehicle, the motor control for steering control, and battery cooling and other key subsystems is critical. Brushless DC (BLDC) motors due to small size, controllability and high efficiency The widely used. brushless DC motors are increasingly being used to eliminate the belts and hydraulic systems, to provide additional functionality and improved mileage. magnet costs continued to decline and control of brushless DC motor of the electronic devices Compaq Presario V2000 battery(compaq v2000 battery) needed to continue to reduce the , leading to more and more used cars, power level is also rising. "

Chan Chung-yan, went on to explain, DC brushless motors are usually controlled with one or more of the rotor position sensor used in conjunction with, because their electrical excitation must be synchronized with the rotor position. For the cost, reliability and mechanical packaging reasons, especially if the motor need to being immersed in a fluid, preferably in the case of sensorless brushless DC motor running - that is, without sensor operation. Sensorless motor lower cost, because it does not require sensors, but the driver is more complex. Sensorless Motor in Hybrid Electric Vehicle Battery cooling system has excellent performance, this time do not need to start and stop the motor. "Automotive system designers embedded in the face of changing environment, the need to develop a cost-effective and environmentally friendly solution. Low-power micro-controller is an important device to meet the demanding requirements, which can increase the cost of lower reliability of the system in a small package to adapt to a smaller board space, and no external components. In addition, to have the socket, software and peripheral compatibility with micro-controller architecture provides designers with excellent flexibility, enabling them to shorten the development time and reduce costs. Microchip Technology offers a variety of micro-controllers and DSC, for facing the challenges of hybrid demand for automotive electronics designers is the best solution. "

In the powertrain systems, Cao Yu think the biggest challenge is how to coordinate the motor system and the traditional power system operation, give the user a better driving experience. Improve the efficiency of the whole system mainly from the following aspects: improving compaq Presario M2000 battery(compaq m2000 battery) motor system efficiency, braking energy feedback rate, reducing the efficiency of the engine at low speed range of operation and so on.

For motor control, Kang Xiaodui Freescale, "said Freescale's gasoline engine management electronics a global leader. We offer advanced embedded controllers, sensor technology, power management components and power brakes drive, so that the new vehicle more economical, and protect the environment. We're still the engine control technology introduced into the electric vehicle control and management, and based on PowerArchitecture Freescale processors MPC55/56xx series offers many of the most advanced engine control, vehicle management, electrical drive, battery management solutions. "

Battery management is facing the biggest challenge

In the (full) hybrid vehicles, the battery is the most expensive, but also the most delicate parts. Although the lithium battery with high power density advantages, but in the development of suitable batteries for hybrid cars, there is still a lot to be done. In this case, the next few years, nickel-metal hydride (NiMH) batteries will still be more and more widely used.

Hans-PeterHoenes pointed out that to achieve the fast charge without damage (damage) batteries, designers need a very precise charge (charge) control technology. Although the micro-controller integrated intelligent programming algorithm is basically a software solution, but Fairchild continued to focus on the hardware. In order to avoid interference with power lines during charging, a good power factor correction solution is necessary, to some extent even a legal norm requirement. The control IC Fairchild has an extensive product portfolio, combined with built-in with a soft-recovery rectifiers (performance of the rectifier diode) and low saturation voltage drop across the IGBT, can provide a complete Hp Pavilion ZE2000 battery(Hp ze2000 battery) solution.

In the battery management, Cao Yu Li-ion battery that Infineon has a dynamic balance of Application patents, can reduce the differences between each other, effectively improve battery efficiency and longevity. This patented feature is the battery charged and discharged, or any idle time to implement power balance, very suitable for automotive power applications in such diverse environments and rapid mode switching needs.

"In view of current technology, battery technology is the hybrid cars and electric cars key. Even a relatively high market appeal hybrid cars, batteries account for the cost of the vehicle's 1 / 3 or more. But also the weight of , reliability, longevity and many other issues to be resolved. lithium iron phosphate battery technology should be a better solution. However, as regards the above problems still need further improvement. Fuel cells are another technology, its technical maturity, fuels (mostly liquid hydrogen) storage and control issues, we can say can not immediately become a mature, mass-produced products. while pure electric cars, hybrid terms, the battery cost, weight, reliability, life , including the charging issue will be the government, automobile companies are facing a major problem. "Kang Xiao Dun said," So, the current hybrid vehicles in Europe and the United States and Japan, and has become industrialized, and domestic still in its infancy, there is no formation of industrialization. As the world's leading automotive semiconductor manufacturers, Freescale is committed to the Chinese domestic automotive electronics contribute to the development. Our key customer support (such as BYD, etc.), including Hp Pavilion DV4000 battery(Hp dv4000 battery) technical exchanges, product pricing and so on. "

IBM laptop battery Precautions

2009-11-04T23:44:00.003-08:00

IBM laptop battery Precautions
Should pay attention to the use of questions:

Laptop battery is a kind of "consumables," the degree of damage depends on the battery Laptop Battery when you use the battery for the correctness of the operation, the operation mode, operating frequency, the working environment temperature, storage time (for unused batteries), etc. factor.

1. Laptop battery charge and discharge frequency is directly related to battery life, in general the number of lithium battery charge and discharge of about only 400 ~ 600 times, improved product nothing but 800 times, each time the battery charge on the end to the use of a step forward . (When the power of 85% or less of the battery charge, will be recorded and to increase the number of times on a single charge.)

To this end, when the battery Compaq EVO N410c Battery voltage is greater than the battery-management process set starting value 96% charge, and your current place in which there is 220V AC power, they should make full use of AC power and minimize the number of notebook computer battery charging, to prolong battery life.

At this point the battery do not have to remove from the machine because it will not start more than 96% of the electricity to recharge the battery. But even so, if you are a long-term use AC power and rarely used the battery, it is recommended, or remove the battery from the machine to compare the good, because the long-running laptop heat generated when the battery will cause some damage. It should be noted that in such a case, once the AC-powered power outages, you have not saved data will support the absence of cell loss, this was a failure, the user must carefully Compaq EVO N400c Battery weigh.

2. When the power is 3 ~ 5%, it should be timely to charge the battery, or battery self-discharge phenomenon will cause over-discharge and damage to the battery, charging the machine and may be shut down, suspend any other state, you can also charge while edge use.

Laptop charging must be a full, otherwise it will damage the battery. This is based on reduced sufficient to avoid an increase with cycle number of charge cycles and shorten battery life; rather than due to "memory feature" issue, lithium batteries, unlike nickel-cadmium Compaq Armada M700 Battery batteries and nickel-metal hydride batteries have "memory characteristics", lithium batteries do not have the "Memory characteristics. "

If charging machine at shutdown or hibernation, when the charge to 3 ~ 4 hours after the green power status indicators are no longer beating, the time has reached 100 percent capacity, it is timely removal of the AC power plug to prevent excess charge on the battery The damage the battery.

If charging machine was waiting, hang, or side with the state of charge while, then when the charge to 3 ~ 4 hours after the green power status indicators are no longer beating, the battery will automatically exit charge state.

Charging process will carry out a fast-charging, when the power status indicator light yellow (Chang-liang), filled to a certain a certain value into the thin trickle charge current is slow, when the power status indicator light flashes green the color becomes ; has been filled with 100%, after, it becomes green (Chang-liang) of the. Lithium battery charging process is the constant pressure approach, and began charging voltage that will soon stabilize, while the current is getting IBM FRU 92P1121 Battery smaller and smaller.

3. Power is not fully depleted before (ie electricity at 5 ~ 100%), not to recharge laptop batteries, otherwise they will reduce the charge to increase with the cycle number of charge cycles and shorten battery life.

When the power is 5 ~ 95% battery should be used, so the use of AC power adapter will charge the battery (charging side by side state).

4. When the power is 96 ~ 100% or the battery removed from the machine can use the AC power adapter switched on, use the AC power adapter AC power adapter when you please put the DC output plug on the plug into the machine, and then AC power plug to plug it into 220V ~ socket; removed when the AC power adapter should be first, and then unplug the AC power plug from the machine, unplug the AC power adapter DC output plug. Otherwise, they might damage your equipment.

Using the AC power adapter, when the AC power plug to plug it into 220V ~ socket, while the power status indicator on the machine yet, gave the former IBM FRU 92P1125 Battery (Note: During this period of about 5 seconds time), please press the power button to turn; shutdown or go to sleep, in addition to green power status indicator lights have been extinguished all the other things, make a timely manner from 220V ~ unplug the AC power outlet plug (not later than 5 seconds), AC power plug pulled out in about 5 seconds , the green power status indicator light turns off; otherwise the battery will overcharge and damage caused by the battery. Off state due to AC power adapter is still non-discharge state, the system's power management procedures and battery power management chips from inside the interface circuit composed of about 5 seconds will be automatically transferred to the "off state of charge", recharge the battery IBM 40Y6793 Battery. (If necessary, may from time to unplug from the machine on AC power adapter's DC output plug, this time the battery will discharge through the AC power adapter reverse.)

If the suspension of work in order to wait for the machine to enter, or suspend state, not from 220V ~ socket unplug the AC power plug; so when the machines still have the power to maintain.

5. IBM in ThinkPad notebook computers information technology indicators have highlighted the "laptop battery" is the manufacturers are measured under the conditions specific to the indicator used in our normal notebook can not be achieved under the conditions of , such as: information technology-related indicators have highlighted the "battery" for 4 hours, we can only get the normal use of about 3.5 hours of battery power supply. If the difference is very far, and is still under IBM ThinkPad Z61t Battery warranty, dashing contact IBM.

How to test the power supply laptop battery time

Grasp of how to make the battery Compaq Presario 1200 Battery power supply can be longer, many notebook computer users are also very much like to master the battery performance and understand their own batteries in the end how much time to work to avoid when the battery is an urgent need for "strike" situation. But how can we correctly understand their own laptop battery time? Here we introduce a method is the use of BatteryMark4.0.1 software to test battery life.

Test Principles

Battery Mark test principle is to use the built-in four engines to simulate the actual operating conditions to consume Compaq EVO N620C Battery battery power. This four engines are the Graphics engine, Processorengine, Diskengine and Thinkengine.

Graphics engine built-in Battery Mark by calling the procedure a sample, such as Photoshop, Dreamweaver, etc. to simulate the actual use to deal with graphics, web pages and documentation process.

Processorengine to CPU occupancy rate increased to 100% instantly and maintain a period of time to simulate the CPU high load power consumption of under working conditions.

Disk engine through Compaq EVO N610C Battery repeated read and write operations on the hard disk to simulate the actual use of the power consumption of these drives, when you can see the hard disk light flash in the mad.

Thinkengine is a simulation of the actual situation of users in the process of thinking.

Test, Battery Mark will be in the 4 cycle engine, constantly switching between, followed by testing a variety of operating environment, this four engines can be fully integrated with the specific circumstances of the test battery. Each had 2 to 3 minutes Battery Mark test data will be automatically saved to the user to set the directory below. Completely exhausted the battery Compaq EVO N600C Battery in a notebook, laptop computers automatically shut down the last time before the results will be saved as the final test results.

Laptop batteries used in three important issues

Laptop batteries used in three important issues

The use of laptop computers are more and more, and it has brought to the user ease of use, let us fully enjoy the fun brought by mobile office Laptop Battery. But have you ever thought, what is so convenient for notebook computers? In fact, is its battery, no battery on the laptop in functionality and general desktop machine there is no distinction between. The battery is also a notebook inside the expensive consumables, and its longer life span of our use of lower cost, and now we have to talk about how to maintain the use of your battery.

(A) whether it is necessary to activate a new laptop battery

In fact, the activation of the battery Compaq Armada E500 Battery work in the factory should have been completed, notebook battery factory brought in a little power is the natural wear and tear in order to avoid damaging the battery. Activation of the battery should be in no circumstances to protect the circuit, the can itself with a lithium battery protection circuit, designed to block the circuit aim is to avoid excessive battery charge and discharge, generally when the battery is fully charged, charging indicator light out of that moment, the battery is not in the state of charge, then this time you then plug in the charger plug to charge the above do not have any significance. We can see on the status of the battery if the battery is charging, there is a simple way to determine whether the battery state of charge, the battery charging time will be distributed at a certain degree of heat, when the battery is full after one hour (battery charger Power plug temporarily pull down), you go touch the battery, this time you will find that the battery is at room temperature, this is no longer at this time because the battery charge state, and of course, there will be no heat Compaq Presario 1700 Battery generated.

(B) how to properly charge

Whether or laptop using the lithium-nickel-metal hydride battery cells, these batteries are all memory effect, Ni-MH battery has obvious memory effect, lithium also has memory effect, but its memory effect relative to the nickel-metal hydride only smaller. We have heard of the so-called memory effect lithium batteries do not say, but that is exaggerated in some JS to say the purpose of the guidance is wrong to consumers. Since the lithium battery has a memory effect, then the charging should try and run out of electric re-charging, it should not want to charge when the charge went, so that although the convenience of using them, but it will shorten the battery life. However, we have absolutely no need to fully used up Zaiqu isoelectric charge, this is too cumbersome. While this is due to the battery protection circuit is not under the protection of Bu Zhiyu damage the battery, but nothing special needed. In fact, in less than 3% of electricity can be charged, and the memory effect is still an objective reality, but natural wear and Compaq Presario 900 Battery tear than it already is not what it is.

In fact, this depends on when you are using an external power supply is not need to charge the battery, and battery charging frequency is directly related to life, under normal circumstances the number of Li-ion battery charging and discharging are fixed number of charge cycles generally only 500 or so  activities make whispering sound the buck-for-Ke ? 00 times. Each of us to the battery to recharge a battery, the corresponding, thus reducing a number of charge Compaq Presario 700 Battery cycles. But now many notebook manufacturers have taken into account the vulnerability of the battery in order to increase the protection of the battery technology, does not meet certain conditions will not be charging. Even so, when you use computers a long time, when using an external power supply is recommended that you unplug the battery because the battery temperature is also a killer, one laptop computer use would produce a certain temperature, which is very harmful to the battery. Of course, if you are not sure of their own batteries, then I suggest you bring your laptop battery pull down the re-use an external power supply, because not all batteries have a protection Compaq Presario 1800 Battery circuit.
