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.
