Prevent the safe use of explosion-proof steel cell phone guide

The new year, Guangzhou, an explosion took place with the mobile phone of Laptop Battery deaths from injuries once more to alert the country more than 600 million mobile phone users, though it has denied media reports the origin of the explosion of cell phone or battery, but still a lot of people stepped up, "beware of poor quality cell phone batteries, cell phone-free variable 'grenade' "idea, in short sentence: the use of mobile phones to be careful.

The most deadly steel battery

Practitioners in the mobile phone industry, according to a person who for many years, currently the battery casing material generally have iron (steel), aluminum, film of several materials, and if an explosion blast steel battery could be fatal.

Aluminum shell in the hot overvoltage overcurrent situation would be inflated, but the relatively soft aluminum so that the characteristics of the battery is not easy to explode, expand to a certain extent it will open the next, the gas will come out. At this time despite the battery end of life, but will not explode, but pay attention to, run out of gas If you are experiencing high temperatures, will continue to burn or even explode.

The shell is used for original film and big brand batteries Sony VGP-BPS10 battery, is a relatively safe one, with the protection device, explosive probability is very low, even in the face unusual circumstances, will automatically cut off power supply, so that the battery can not be used, but it will not happen explosion.

Steel (steel) shell contrast to the above two kinds of battery manufacturing cost of the most expensive as it is more hard sharp, no flexibility, the battery internal explosion, the iron and steel debris will immediately exploded, with high slit people's skin, make mobile phone into a a small bomb, could be fatal.

Teach you to distinguish fake batteries

It is, at present the market of fake and shoddy battery there is a common problem: the battery inside the battery chip core components of poor quality, insufficient charge and discharge time is short, anti-sabotage poor performance, the marked discrepancies with the actual battery capacity.

The genuine mobile phone batteries generally have the following exterior features: battery Sony VGP-BPS9 battery label use of the second printing technology, in a certain light, and from the slope of view, part of the color bar code significantly more than in other parts of the black, and Mo Shangqu hand feel than other parts of slightly convex, many with original equipment batteries have this characteristic. In general, the superior performance of the cell phone battery, an internal over-current protection device, once the external short-circuit the phone, give rise to significant impact on current, the overcurrent protection device can automatically cut off the charging circuit in order to avoid cell phone batteries due to high current the impact of the phenomenon of the event of damage or burning. The bad battery is likely that there is no over-current protection device, so charging the battery after a long period, the battery shell may appear the phenomenon of boiling, the worst case, smoking behavior may occur. If the battery charge did not take long, hot phenomenon appeared, then the likelihood, the battery Sony VGP-BPS8 battery is defective.

The safe use of mobile phones

Try to use the original battery and original battery charger; Do not put the battery under high temperature environment, while avoiding direct sunlight in summer; in charging try not to call; Do not phone hung on the chest; as much as possible on the mobile phone bag ; phone encounter in the course in use of water, must immediately turn off the phone remove the battery power as soon as possible repair, or cell phone hair dryer drying moisture inside (only available heater), water erosion can also reduce the extent of board ; in a clean cell phone, dip a soft cloth can be used with low concentrations of dishwashing detergent and then with a soft cloth immersed in warm water, wring dry cleaning, pay attention Do not use other chemical Sony VGP-BPS5 battery reagents.

Why can not laptop battery maintenance and replacement of batteries?

Why can not laptop battery maintenance and replacement of batteries?

Laptop battery structure is not complicated, the simple answer is that the batteries with protection circuit, the battery Toshiba PA3107U-1BRS Battery is the core of batteries in series or in parallel, which we usually see on batteries with the general cylindrical shape similar to the fifth battery just inside the stored energy of the chemical solution different manufacturers have designed over-current, over voltage, over charge, over discharge, temperature, etc. to protect.

Cell structure even though a simple, but really qualified to make a battery is not that simple. A product must first select batteries, bad batteries are often internal resistance, voltage, charge and discharge targets difficult to meet the demands, to do out of the product is mixed. At present regular multi-purpose manufacturer Sanyo, Samsung, Toshiba, LG, BAK and other brands of batteries. After storage batteries must be tested for their targets and indicators within the 2% difference in the batteries can be paired in series or parallel circuit composed of, otherwise, a target of batteries and other batteries because of quite different in the battery charge-discharge process will be expressed as battery charge or discharge have not yet succeeded, and this individual has been over-charging batteries, or discharge, resulting in the battery pack does not work, the difference in the long term the larger batteries, or over-charging After discharge, leakage or even an explosion that may arise. Manufacturers of batteries for testing and matching precision instrument and equipment, not the general computer Laptop Battery to rely on the city so-called professional maintenance staff will be able to complete the multimeter, and they rely on multimeter can be achieved at best is to control the batteries internal resistance within the required accuracy, as Actual storage capacity batteries, life, charge and discharge the effective time, no professional equipment can not detect a real sense can not be matching, so-called maintenance is also a form, the battery storage capacity has not increased maintenance will not .

Laptop battery life is generally 300 times the total charge and discharge, a year and a half or so to replace a new battery, original laptop batteries are not cheap, easily a thousand, some friends in order not to spend so much money to buy replacement laptop battery while the thought of batteries, which should not be it? This is what security risk it?

At this point, I visited the electronics market, engaging in business transactions, both second-hand laptop, said to the writer that can provide this is what they call "changing core" of the maintenance service. In the author in the hands of IBM 600E original equipment batteries, for example, "for the core" costs about 100-300 yuan, and its process is very simple, just have a basic welding equipment and technology can be completed. In the laptop battery maintenance of the site, the reporter saw repair personnel forced open the original battery, will the old batteries out, Toshiba PA2487U Battery and then as is in accordance with the new batteries into the spot in turn connected to come, and the entire process did not exceed 30 minutes. "In fact, the majority of laptop batteries are not rechargeable batteries as a result of aging, as long as the battery charge and discharge control circuit board not bad, this maintenance of nearly 100% success rate." Merchant says,

Maintenance business also revealed that the current batteries in circulation are from the South to buy large quantities. Battery heart repairs until early this year, appeared in large numbers in the local electronics market, but also very popular. "In the 'blue fast', where the block to buy a new battery at least 1,000 yuan more than the price that many customers are cheaper to come to this for Ben Zhao."

I interviewed a number of IBM Sony PCG-Z505 battery products is responsible for after-sales service "Blue Express" the staff, for this "change the core" behavior they both said that did not know, nor did conduct a customer complaint. However, a staff member confirmed that the purchase of a new 600E battery needs to spend about 2,400 yuan, it can be said is equivalent to half the price of a home notebook.

For the difference between the price disparity, "Blue Express" the head of the Propaganda Department, said, IBM has its own global pricing strategy, the company did not modify the permissions, but whether they would opt to repair the battery is the client's freedom. At the same time because of environmental considerations, IBM customers will be turned over to the scrap batteries, commissioned by professional companies to focus on the destruction, the process takes a lot of money.

In view of "cheap convenience" of the laptop battery for core process, professionals advise that this "change core" cell there is a certain security risk.

"Blue Express" the technical staff, told reporters without permission "for the core," there is a big security risk, some rechargeable batteries without the detection Sony PCG-V505 battery of short-circuit even after the burst phenomenon, ranging from damage to the host, while in the explosion , and even life-threatening to the user. This is really unwise to be too uneconomical, not as good as OEM notebook computer batteries to buy it. In fact, many claimed to be original battery is OEM, as the industry brother DELL, there are parts which are not OEM's? OEM notebook batteries batteries are imported genuine manufacturers, performance, and original little difference, because it is produced domestically (mainly in the south a few makers), low-cost and no import tax to pay so much, so Only one-third of the price of imports or less. In addition to the battery-for-core insecurity, the provision of core services for businesses and maintenance of the level of uneven quality, in and chat in a business that, some black-hearted battery maintenance providers, in order to earn huge profits, take the quality of the best times cells act as a good battery, and the worse the battery inside the control chip removed, only one wire connected to, or have already been scrapped on the circuit board inside the battery charge a few. Said that a serious point, so that the battery Sony PCG-R505 battery can not think of are all very hard.

Electric vehicles with lithium-ion battery packs and battery selection

Electric vehicles with lithium-ion battery packs and battery selection

Currently hybrid (HEV) and plug-in hybrid (PHEV) in the commercial mass production and gain more market share, the main obstacle is the battery Laptop Battery. Electric vehicle battery must be used in high-performance, low-cost, long life and high safety performance. Lithium-ion batteries are most likely to meet these challenges. At present, all over the world to do the appropriate research and development to improve the battery characteristics. But even the best battery performance, combined into a poor battery pack battery pack may also lead to overall performance, reduced life, security, deterioration of which led to increased costs. In addition, we also must take into account machinery, packaging, electricity, heat, security, monitoring, control, and other parts of the interface with the vehicle and other issues.

Batteries from the battery pack is generally composed of modules or single cells. A battery module also formed by a number of single cells. Loaded in a battery of electronic and thermal control of the box, this cabinets there is a whole battery system with the vehicle interface to other components of the facilities, and battery management systems. Each module also has its proper packaging, thermal control and mechanical or electronic equipment. This loaded with batteries, thermal control and Sony PCGA-BP2T battery electronic equipment, and other parts of the box is what we usually refer to the battery pack.

Battery Select

The packaging of lithium-ion batteries should take into account the following: battery module interconnection between the single cell design; batteries, battery modules and electronic components, the connection between the specific design; structure subject to shock and vibration protection; how to battery pack for collision protection; select the ideal fixed in position of the vehicle; and vehicles other components of the mechanical interface design. Therefore, in the initial design of battery, it must take into account: safety (abuse of limitations); the entire system of packaging costs; of packaging the life and durability of effects; packaging recyclable and re-use of; manufacturing costs; maintenance / repair of convenience; thermal management (because of temperature influence battery life and performance); electronic monitoring and control; display performance, capacity, recession and so the measurement facilities. Therefore, in the initial selection of a suitable type of battery, battery pack for the packaging Sony PCGA-BP2S battery, interconnect design, thermal management, are very meaningful.

Battery Safety

Security is the largest lithium-ion battery concerns. Abuse trials, over-voltage, over charge, over discharge, overheating, nail puncture, external short circuit, or an internal short-circuit defects and so may lead to thermal runaway and battery electrolyte leakage, smoke damage, openings, fire, or even an explosion. For the application of the battery in the vehicle we should be demanding. Although batteries are by improving the negative electrode materials can improve the safety performance of adding additives and through effective electronic and mechanical control virtually eliminate or significantly reduce the risk of accidents, but are like a pressure and squeeze, as well as thermal runaway caused by internal short-circuit still need special attention. And should therefore be targeted to the battery pack accordingly designed to reduce the impact of these conditions to improve the safety of battery pack.

Small number of large-capacity lithium-ion battery single cell with many small-capacity lithium-ion battery single cell comparative

In the PHEV, HEV and EV on the use of a large Sony PCGA-BP2R battery number of small-capacity lithium-ion battery cell with the use of a small amount of single large-capacity lithium-ion battery single cell is different. For example, Energy CS in the PHEV battery pack for use more than 2000 single small 18650 battery (2Ah). And the Chrysler Corporation in the PHEV battery pack using the 200 a much larger single battery (41Ah). The use of a large number of small-capacity single cells has certain advantages, such as batteries low cost (currently in commodity markets, mostly small-capacity single battery), safety, better (faster cooling), because of the small battery cell while security incidents small size and battery production and processing of higher quality. But there are many drawbacks, including a single cell there are too many inter-connections, requiring higher integration and assembly cost, weight, volume ratio is low, the reliability of difference (integral part of more and somewhat redundant), the need for expensive electrical management . Use fewer large-capacity single cell has some advantages, such as assembly, low cost, weight and volume is high and high reliability (due to the reduced number of connections section). However, the disadvantage is the high cost of batteries, low quality, thermal management becomes more difficult and large-scale security incidents occur. Finally decided to use what kind of Sony PCGA-BP2NY battery trade-off analysis must be based on the specific application.

Cylindrical and prismatic single battery comparison

The use of cylindrical lithium-ion battery single cells and prism (or layers board)-type single cell lithium-ion batteries also have different. Cylindrical single cell can be mass-produced and has a high quality. However, with the battery pack can carry all kinds of vehicles, the shape of the factors of space changing needs, the cost advantage is reduced. Cylindrical design robust and resilient structure, especially the anti-hammer, shock and vibration, can prevent safety accidents. With the cylindrical winding area of single cells become large, its external and internal surface area may be cooling winding layer area ratio is relatively decreased; Therefore, heat transfer and a reduced ability to increase the internal temperature gradient. Prism or layers board design with high external and internal surface area may be cooling stacked around the floor area ratio, easier to carry out thermal management. And the prism-shaped single cell comparable single cylindrical battery provides higher efficiency of the packaging volume. However, if the prism-shaped single cells using a soft-film packaging must also be taken into account in the design to prevent local stress, resistance to hammering, shock and vibration. Corresponding facilities may increase the size and weight, reducing soft packing prismatic single battery size Sony PCGA-BP2NX battery advantage.

Battery Thermal Analysis

Thermal management is a battery in cold environments and high-temperature environments is essential to get a good performance and life. High-temperature lithium-ion batteries to reduce the performance and life expectancy, thus limiting the scope of the vehicle driver (driving range) or performance. Thermal management system of the battery at low temperatures, heating at high temperature to heat the cooling of the battery. The corresponding thermal management cooling and heating system to increase the cost of the battery pack, weight and size. Thermal management is not only in order to maintain the battery temperature is below the maximum limit, but also to maintain the temperature between the single cell uniformity. To improve the battery pack Thermal equilibrium, this change requires a temperature fluctuation in a small area (for example, less than 5 ℃). Therefore, we in the battery pack design, must be based on the thermal characteristics of lithium-ion battery lithium-ion battery type selection and reasonable, and beneficial for the thermal design of the principle of equitable and reasonable battery pack cooling, thermal management system architecture. While ensuring that the system is designed Sony PCGA-BP1N battery with a simple structure, reliable and durable, low-cost and low-power features such as parasitic.

The same kinds of batteries at different temperatures under the conditions of heat consumption rate is relatively

The same battery at different temperatures heat rate (per 1kW h of electricity generated by the consumption of calories) is not the same, this is because the battery's internal chemical reaction and temperature are closely linked. Shown in Figure 3, the ambient temperature on battery performance is very affected. Ambient temperature is lower, battery run-time will be more heat produced by the reaction itself. In the battery within the normal operating temperature, the ambient temperature the higher the battery self-generated heat is relatively less chemical energy consumed by the less efficient. This is because the battery with the surrounding environment, there is heat exchange. Thermal Management should ensure that batteries in their optimum operating temperature range of environments to improve battery efficiency and to ensure that all battery operating temperature of the surrounding environment, consistency in order to ensure that all battery operation status in line.

The same type of battery comparison of different shapes

Layers are generally rectangular battery type, battery is a cylindrical winding type. They are not the same as all manner of packaging, thermal characteristics of different structures exist due to a corresponding difference. Different sizes of cylindrical and rectangular shape of the heat distribution of batteries is not the same. As the cooling surface area of different sizes, the thermal gradients within the battery are also different. Figure 2 rectangular battery W / L big sense that there is a large cooling surface area, the internal temperature Sony laptop battery less heat better performance.

In view of different shapes of cylindrical lithium-ion battery temperature field to be more intuitive, we analyze the same type of different radius, different sizes of cylindrical battery capacity vehicles in the same state, the internal temperature field. Here are two 20Ah batteries in parallel is equivalent to a 40Ah battery.

40Ah battery can be seen within the internal temperature 17 ℃ and 16% of the current density uneven. The two 20Ah batteries in parallel the same capacity battery, only a single cell within the 10 ℃ of temperature and 6% of the current density difference. Large-capacity battery temperature gradient larger, mainly due to the battery cooling surface area caused by a relatively smaller proportion. And experimental analysis of the two 20Ah batteries in parallel drawn more than a 40Ah battery life longer. This explains the application of some of the advantages of small-capacity battery.

Modular approach with different kinds of batteries Comparison

Battery pack is sometimes formed by a number of single cells of the battery modules. The thermal characteristics of single cells vary in their composition of battery modules, due to the number of combinations, as well as the arrangement of battery modules packaged in different ways is also very different thermal characteristics. Therefore, we select the appropriate single battery while also considering forming a modular way, the number of single cells, batteries and packaging methods display arrangement.

We are a group of health heat a smaller force for EV God prismatic lithium-ion batteries Hp PB991A battery liquid ventilation condition in the absence of the temperature field of thermal analysis simulation. Simulation Man-rechargeable batteries in the 1C discharge to the cut-off voltage of constant current state of the battery pack (module) temperature conditions.

The ideal battery pack temperature field distribution shown in Figure 4. Assuming the surface to ensure that each battery heat exchange with the outside world the same boundary conditions.

Battery into the teams actually placed around the different conditions and central cooling. The surface of each battery thermal boundary conditions are different, resulting in an overall temperature difference exists, that produce heat concentrated among high temperature, low temperature edge of the phenomenon (Figure 5).

Composed of a small single cell battery module, the temperature imbalance is relatively small. Composed of modules, the greater the number of single cells, heat the more obvious the phenomenon of concentration. As shown in Figure 6, when a large number of single cells will appear more densely placed in the temperature inhomogeneity, battery pack inside the single cell within the battery module temperature will be greater, there are 45 ℃ great. The small number of single cell battery module composed of densely placed together, the temperature difference is only about 1 ℃.

Such batteries are used in a smaller heat of the small-capacity battery EV, and is smaller in the heat of the vehicle running state did not take a mandatory cooling of the battery module. The actual vehicles in the battery operation of complex, heat increased significantly. For the larger heat applied to PHEV large capacity battery, battery current single large heat rate is higher, Hp PB994A battery resulting from intensive display the temperature imbalances will be more apparent. Module, the temperature difference between the single cell will be increased. Seriously affect the consistency of batteries, but also result in potential safety problems, which makes the overall performance of battery modules greatly reduced. Then on the need for effective thermal management of battery modules to take air-cooled and liquid cooling, if necessary, to take a better performance of phase-change materials as heat transfer medium to carry out thermal management. Therefore, we have selected, after a reasonable single cell type but also the right under the battery characteristics of the modular approach selected, select the appropriate number of single cells, placed in the module package arrangement, as well as methods.

Battery pack should be reasonably designed to play the best battery performance, but also taking into account machinery, packaging, electricity, heat, security, monitor and control many aspects, as well as other parts of the interface with the vehicle and so on. When we select the battery, it should be fully taken into account select the appropriate type, the appropriate modular model, a suitable arrangement of display and packaging options. We can see that the selection of the battery pack and battery performance have an impact, and in severe performance degradation caused battery pack, cost increase, and has potential safety problems and so on. At the same time there is an urgent need for battery manufacturer's concerted efforts to create the optimal storage Hp PB992A battery battery for electric car use.

Nissan North America manufacturing engineering and vehicle manufacturing engineering, said Mark Swenson, vice president of Nissan in 2012 to reduce the cost of type Leaf electric car plan involves manufacture of batteries and battery in the vehicle manufacturing plant will be assembled into battery packs.

Swenson said, "We plan to plant all day uninterrupted production to production facilities enable us to maximize the investment.; He said, Leaf North America, but Nissan plans to sell several models of electric vehicles.

A123 Systems Inc.'s Vice president of Business Development Ric Fulop said he believes that as the industry matures, the cost of the battery pack can be reduced by 9% Sony PCGA-BP71 battery per year. To make a stronger battery power can save some costs, while also optimizing production processes and the use of high-quality materials to cut other costs.

More Power

Dow Chemical Co.'s Global business development director of the Department of Ravi Ramanathan Sony PCGA-BP2V battery said that the cost of the battery power can also make a stronger and more efficient batteries, as well as quality control during production to be cut out.

Automobile manufacturers do not talk about hybrid and electric vehicle battery packs used in cost. However, some estimated to be Chevrolet Volt lithium-ion batteries used in the cost estimate of about 8,000 U.S. dollars.

Ramanathan said, "the high cost of the Sony PCGA-BP4V battery battery, you must come down.; He said that the initial cost may be high, because the car manufacturers of cars and batteries to over-designed to ensure that consumers do not appear on the technical loss of goodwill mechanical failure.

Battery recycling method of hair

Battery recycling method of hair

In this increasingly motorized world, the role of the battery Laptop Battery is very wide. It is for our cars, mobile electronic devices and everyday objects used to provide electricity. We can even use plants to manufacture batteries.

The equipment used batteries according to classification (for example, "car batteries", "mobile phone battery", etc.), also classified according to size (such as "9-volt battery," "button cell", etc.), but from scientific point of view , the battery is in accordance with its contained metal names. Taking into account the need for recycling, the battery's name becomes very important, because it can help you understand that in the end inside a small cylinder contains something.

Battery recycling is not an optional thing, depending on the efforts you are willing to pay, but also depends on where you live. If it is in California, where the words, all the batteries are considered hazardous waste, and asked to be recovered, or sent to a family of hazardous waste (HHW) collection points.

In listing the different cell types and recovery methods, please consider the following two points:

1. Rechargeable battery life is much longer than disposable batteries, hence the use of rechargeable batteries can reduce the quantity of batteries Toshiba PA3084U-1BRS Battery to be recovered;

2. All have limited battery life, but you can use a number of measures to extend their useful life.

Alkaline manganese batteries

Many household appliances will use in alkaline manganese batteries.

Common equipment: alkaline manganese batteries can be used for any device, from cameras and flashlights into the remote control will use it.

Recovery Method: In the U.S., if you Consult your local solid waste management department, they may let you be thrown into the ordinary alkaline manganese batteries trash. This is because, adopted in 1996 "batteries (including rechargeable battery) Toshiba PA3098U-1BRS Battery mercury management act" and demanded the cessation of the use of mercury in alkaline manganese batteries, so throw them in the garbage dump in it does not matter. This does not mean alkaline manganese batteries can not be recovered.

If you decide to alkaline manganese batteries, then thrown into the rubbish bin --- which are legal in most places --- you can also take the following measures to prevent the disclosure of:

1. Will be a number of battery installed in the same plastic bag;

2. Sealed with tape at both ends of each battery.

Recycling Results: The recovery of these batteries can get steel and zinc, which are two very valuable metal. The steel can also be further processed into steel bars.

Ni-Cd Battery

Nickel-cadmium battery that is low-cost version of the rechargeable alkaline batteries.

Common equipment: nickel-cadmium batteries that is low-cost version of the rechargeable alkaline batteries. They can be charged hundreds Toshiba PA3331U-1BRS Battery of times in order to avoid a one-time battery recycling, usually, they can be exchanged with the alkaline batteries.

Another non-cadmium battery is a nickel-metal hydride battery (NiMH), rechargeable batteries that can be a lot of brands are often nickel-metal hydride batteries.

Recovery Method: There is a nickel-cadmium batteries on a small common sense, that is, its part of the price includes the cost of its recycling. Because it contains toxic levels of cadmium metal, these batteries are hazardous waste, can not be discarded in the garbage dump.

In 1994, the rechargeable battery Toshiba PA3166U-1BRS Battery industry formed the Rechargeable Battery Recycling Corporation (RBRC), in thousands of retail stores and public places to provide nickel-cadmium and nickel-metal hydride battery collection points.

Recycling Results: The two battery recycling need to be heated to the high temperature metallic nickel and iron from the low-temperature metallic zinc and cadmium in the isolated; some metal solidified after melting, while others re-treatment as the metal oxide . These metals have a certain value.

Lithium-ion battery

Lithium-ion batteries commonly used in mobile phones and consumer electronics.

Common equipment: lithium-ion batteries used in one of the most advanced rechargeable technology, commonly used in mobile phones and consumer electronics. These batteries can be used as electric vehicles power.

Recovery Method: usually in the recycling lithium-ion batteries, also means that you are recycling your electronic equipment, for example, to the mobile phone Toshiba PA3191U-1BRS Battery replacement, or sell the laptop. In most cases, handling of electronic equipment, the company will deal with the battery. Therefore, you can easily find recycling sites.

Recycling Results: These battery-recycling methods and the same nickel-cadmium batteries to generate the useful metal.

Do not store lithium-ion batteries or throw them in garbage dumps, one of the reasons is that, when their exposure to high temperatures, there may be overheating and explosions. If you are recycling lithium-ion battery before a large number of battery storage together, need to remember its place in a cool place.

Silver Oxide Battery

, Also known as micro-batteries, button batteries; such as hearing aids and watches, like the object will usually use these batteries.

Common equipment: This is a relatively common button batteries, commonly used in calculators, hearing aids and wristwatches. In addition to its small size, the button battery Other features include a longer storage life, and can be used at low temperatures as usual.

Recovery Method: silver oxide batteries Toshiba PA3285U-1BRS Battery and other mercury-containing button cell, so the recovery is necessary. But because these cells are relatively rare, and the service life is longer, you will not have too much need for recycling button batteries.

In most cases, there are professionals to replace the batteries, so you can ask whether they can help you recover the battery. Button batteries have a alphanumeric code, its first letter is the type of batteries you use ( "L", said manganese dioxide, "S" said the silver oxide).

Recycling Results: The silver oxide battery will usually be crushed in the recycling process to recover useful heavy metal lead-acid batteries

Lead-acid batteries are used in automation equipment.

Common equipment: These batteries are used for automation equipment, power supply, such as cars, boats, golf carts, Toshiba PA3384U-1BRS Battery motorcycles or lawn mower.

Recovery Method: Similar to other cells. Recovery of lead-acid batteries up to 97%, which is the highest of all U.S. consumer goods. This is good, because they contain lead and sulfuric acid, is a garbage dump, one of the most dangerous objects.

If you buy a new car batteries can be installed, when asked about the old battery recycling methods.

Recycling Results: for recycling, the lead-acid batteries will be divided into three parts: plastic, lead and sulfuric acid.

* PP plastic will be reprocessed into new batteries shell;

* Lead sheet will be further processed for use in new batteries.

* The battery acid will be based out of and through the sewage treatment plant for cleaning; Otherwise, it will be converted into sodium sulfate, used clothes and cleaning agent.

Other Batteries

If you have other types of batteries, first thing to do is to determine the chemicals it contains Toshiba PA3383U-1BRS Battery to determine that it is not hazardous waste. If it contains cadmium, lead or mercury, then it means that the family of hazardous waste (HHW), in need of recycling.

Misunderstanding the use of lithium-ion batteries

Misunderstanding the use of lithium-ion batteries

With the cell phone, PDA, DC, DV, as well as MP3, MP4 and other new Laptop Battery digital products, rapid spread, people from accessing opportunities for lithium-ion batteries sharp increase. As usual the energy to power the battery, naturally important, because its performance will directly affect the pros and cons of the normal functioning of the device. I believe anyone who do not want to face a critical moment of awkward half-way without electricity, care and maintenance make good use of lithium-ion batteries have become a necessary part of digital products. However, since most people do not quite understand the characteristics of lithium-ion batteries, in the course of daily use easily into a number of errors, not only seriously affect the battery life, but also resulted in a waste of social energy. Here we will talk about the five common errors.

Misunderstanding 1: the larger-capacity battery the better

In a sense, this view is indeed correct. Set aside the price and weight, the same model with the volume capacity of the battery of course, the bigger the better, the capacity to provide higher the longer the time to work. However, there is some manufacturers to produce large lithium-ion battery nominal easy more often than not in improving the effectiveness of the efforts to improve Toshiba PA3591U-1BRS Battery cell materials, but uncontrolled electrode stabilizer added to the relative decline, and that the battery while measuring up the first volume is indeed very Great, but after dozens of recycling capacity will be quickly depleted, leading to rapid obsolescence, and those electrode stabilizer sufficient, low-capacity battery, even if the work in 2023, remain young forever. At the expense of life cycle costs in exchange for the big easy, not something that we pay for it, when you do not want to buy the battery capacity, seek big blind comparisons.

Misunderstanding 2: The battery recharge used in automatic shutdown, can extend the use of time

Re-charge the battery is designed to use, usually we are most concerned about is a total piece of the battery Toshiba PA3506U-1BRS Battery can use for how long. In order to measure to compare different brands of rechargeable batteries for this feature, we introduced the concept of cycles. International regulations in the 25 º C room temperature conditions, with constant current constant voltage mode 1C (Note: "1C" - charge and discharge current unit. Intended for the use of 1000mA current on the 1000mAh capacity battery charge, discharge, or 500m

A current on the 500mAh capacity battery charging and discharging ... ... and so on. ) Charge 150 minutes, is now in order to discharge constant current 1C to 2.75V set only for a loop. When a first discharge time of less than 36 minutes when the counting ended, cycles must be greater than 300 times. And it was felt would reduce the charge and discharge the battery once a life time, so desperate as much as possible the delay time of each use, the battery consumption of the device does not automatically shut down without charge. In fact, need not necessarily be the case, because characterization of lithium-ion battery life cycles of deep charge deep-discharge method is based on the measured, while the actual use of the ever-changing individual user can not be in accordance with international test mode to use the battery discharge is absolutely not a big current discharging constant Toshiba PA3291U-1BRS Battery current discharge. Is usually small current discharge pulse discharge and a hybrid method under conditions of use completely different number of cycles will naturally be different, if the cut-off voltage was increased a few volts to test zero, then the cycles will be greatly increased. In the absence of memory effect nickel-cadmium batteries, lithium-ion battery is very suitable for use with the charge as there is no need to use rechargeable shutdown device, which is precisely the advantages of lithium-ion battery.

Misunderstanding 3: multi-chargers green light after charging for a while, the battery can charge more saturated

In fact, the public is a green light charger instructions, the charge may not eat the whole bread depends entirely on the charger for charging the internal circuit control mode. Charger output is usually after the first constant current constant voltage, that is, the first constant current charging. Current will, the battery voltage is gradually increased as the charging process; when the battery terminal voltage reaches 4.2V (or 4.1V), then changed to constant voltage charging, the voltage must, the current will gradually decrease as the charging process. When the current is less than a certain value (usually set to 50mA), the green light. But the green light after the charging of different chips then respond differently, if it continues to carry out constant voltage charging, and strictly control voltage Toshiba PA3356U-1BRS Battery does not exceed 4.2V, no doubt charge more for an hour can really increase the battery capacity. He fears that face those cheap chargers, while continuing to charge, but its control precision is poor, if not careful the battery beyond 4.2V, and causing overcharge will result in overcharge will seriously shorten the cycle of life. Some charge devices such as T1 (Texas Instruments) and BQ2057 series and linear (Linear Technology) and LT1800 series is completely off at this time charging circuit, not continue to charge, then recharge for 10 hours no avail. There charge pulse mode, such as maxim (Maxim) and 1679 chips, display a green light, the lithium-ion battery has been 100% full charge, and there is no need to re-charge. Moreover, even if the rechargeable lithium-ion battery not too full it will not affect the cycle of life, only single-use significantly less time. In order to avoid irreparable damage, we have general non-technical users to completely remove immediately after the green light to use.

Mistakes 4: Chargers marked the greater Toshiba PA3250U-1BRS Battery the output current, the faster the battery charging

Charger output current size of the subject only to demonstrate its ability to provide current, is not exactly the same as the actual charge current lithium-ion battery, the charge current size also depends on the charge management. Charging management is switching mode, namely the high-frequency pulse-width adjustment (PWM) mode, the charging current is generally much lower than the charger output current. Of course, the above is that lithium-ion batteries in terms of constant current charging. As the lithium-ion batteries are used after the first constant voltage constant current charging mode, in a certain range of current (0.5C-1.5C) in a separate increase in the constant current charging current value and does not accelerate the rate of battery charging and eat.

Misunderstanding 5: The battery is full after the store, can reduce the capacity loss

This idea can be described as wrong, lithium-ion battery is different from the nickel-chromium, nickel-metal hydride batteries, because it has a very bad "aging" of nature, it is in storage for some time, even without the use of recycled some of its capacity will be a permanent loss of reason or the battery positive and negative material from the factory after it has already Toshiba PA3395U-1BRS Battery begun the process of failure. At different temperatures and different charge states of "aging" the pace is different, as shown in the table:

Storage temperature power status

40% of the saturated store 100% saturated storage

0 º C left 98% (one year later) left 94% (one year later)

25 º C left 96% (one year later) left 80% (one year later)

40 º C left 85% (one year later) left 65% (one year later)

60 º C left 75% (one year later) left 60% (3 months later)

As can be seen from the above data, storage, and charge the higher the temperature the more saturated, the battery capacity loss will be more rapid. It is not recommended you to save a long time in the saturation lithium-ion batteries. For the idle hands of the battery Toshiba PA3399U-1BRS Battery, storage, charging only 40% when you try to, and stored in the refrigerator room.

Laptop battery can not charge the battery must have broken it?

Laptop battery can not charge the battery must have broken it?

Laptop battery can not charge the battery Laptop Battery must have broken it? Read below, you should probably understand that a number of laptop battery can not charge causes. In this paper, however, the maintenance department is still a good way!

(In this province, the statement of the segment does not matter)

It so happened that Xiao Li a notebook in hand, needless to say, is definitely send over maintenance of the user do not know what the problem is still followed by go and see.



This notebook is SHARP, and rarely seen in China is estimated that people brought back from abroad. As to the question Han Well, Mike told me that this laptop battery not charging, and others customers have already replaced the battery, but still does not solve the problem, so Take over. And he said to a user or site readers that found in our Romanian workers IBM 92P1075 Battery in contact.

Hey, do not charge laptops, this problem sounds serious, although not delay use, but unprovoked into a mobile notebook PC, which makes things kinda depressed.

Alan told me: "Customers have had to replace the battery, prove that the problem is not something like that, and the notebook is also working properly, then there is only one conclusion is that notebook to charge the battery on the motherboard circuit that damage had occurred. Therefore, this case should apart repaired. "



Process does not elaborate on this, anyway, is what professional people do this, and not five minutes to do, remove the laptop's motherboard has come. We plug in this position, which is battery charging interface, of course, not connected to an external power supply if the case, where is the battery-powered IBM 08K8197 Battery interface.

Alan told me, "it typically does not charge the battery failure was more common, and resolve the problem started from the battery interface. First, take a look at whether the charging voltage output pin in the map should be the right place the first 1, most notebooks are 19V to the battery voltage is used to charge. "Here, Mike began to take multimeter measurement, the results showed that the pins have no voltage output.

"Since this is the case, we will test the battery charging circuit," said Xiao Li Here, the laptop's motherboard turned over.



This part is the battery charging circuit, and is on a photograph, the back of the motherboard, let's look at the parts inside a yellow circle. Here is a diode and a FET, Li was the first measurement of the diode and found that one end of the no-voltage, current in the diode that is truncated before. Well, next we must measure FET, that is, sinking a small 8pin new movie. Li was with the multimeter on a pass in the pin is measured is the amount of small new nor very clear IBM 08K8198 Battery about what the specific volume of the pin, but the conclusions come out soon, and the control FET and no voltage output pin. Alan told me such a conclusion is to explain the problem does not exist in the diode and FET place.

The next step is to test the battery charge control chips, and that is a red circle in the figure above components. Because the earlier measure current into the FET did not, so the possibility of charging chip damage is very great. After the results of measurements, and indeed the problem lies in here, the solution is relatively simple, is to replace a similar chip on it.

Oh, yes indeed forcing men are no weak soldiers, in my eyes appears to be a very troublesome problem, people only took 20 minutes to resolve, and could not help but I do not admire呀. I often think that when the Romanian workers if it is like one-month internship, and presumably will be soaring value of their own experiences of, ha ha!

As the saying goes: Learning without thought is desolate, think without studying is lazy. The problem is solved, but I still remember when the maintenance Xiao Li had told me before, like IBM 08K8199 Battery laptop battery not charging failure is more common, then why does this problem occur?

Li was grinning tell me: "In fact, there is nothing secret, nor is it caused by improper user. We all know that every time the battery charging and plug the process, will have a larger voltage, in the interface side is often will produce sparks, in fact, at this moment is very easy to bring the battery or the laptop motherboard injury. normally used laptop a long time, often after the swap the battery, there could be no question of charging the battery, while the components used, the quality of the motherboard The quality is also very critical issue. For instance this machine, under normal circumstances the instant charge may damage the motherboard high-current power IBM 92P1073 Battery supply line at the end of diodes, but do not know why this laptop Queba supply chips to the burned. Although the cause failure phenomenon is the same, but the maintenance cost is definitely improved. "

呵呵~, do not know if we do not understand, I understand anyway, and also because the users often will result in frequent-swappable batteries this failure. So I would like to advise those who have notebook users do not often repeated the battery removed, anyway, when the laptop is also possible to install the battery charge. So, do not use the battery unless it is a long time, otherwise IBM 92P1077 Battery it has been left alone in a notebook above the bar.

Buy a new laptop battery actual capacity and the design capacity of the reasons that much difference

Buy a new laptop battery actual capacity and the design capacity of the reasons that much difference

1. This cell non-original batteries but the poor quality of the OEM battery.

Such poor use of OEM batteries Laptop Battery are down from the old battery to replace batteries or very poor quality batteries. That customers how difference?

The general performance of the battery market prices are quite low, and the insurance business is generally three to six months so that even Paul did not Paul is also possible. The whole time for a relatively short warranty. Because such batteries customers for some time, capacity will be quickly reduced standby time will be shorter and shorter. It is estimated that the standby time of 30 minutes only to win the next time, you will have to replace the new battery has.

Lithium-ion battery cathode material of lithium active compounds are usually composed of negative electrode is a special molecular structure of carbon. Common IBM 92P1102 Battery cathode material mainly composed of licoo2, charging, added to the battery positive pole of the electric potential to force the release of compounds, lithium ion, embedded negative elements arranged in lamellar structure of the carbon. Discharge, lithium-ion from the lamellar structure of carbon precipitation and re-cathode combination of compounds. Lithium-ion movement generated a current.

Lithium-ion battery capacity after repeated charge-discharge will decline, its causes are complex and diverse. Is mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ion on the hole to accommodate the structure will gradually collapse, plug; from the chemical point of view, is the active anode material is passive, there's the other side to form a stable compounds. Physics will appear on the cathode material gradually falling off, etc., in short, can ultimately reduce the battery charging and discharging process of the free movement of the number of lithium-ion.

Therefore, lithium-ion battery scrap battery factory to the final date, the IBM 08K8196 Battery performance of its capacity is to use a little time.

2. Battery factory battery factory to the user's hands for too long, short is 1 month or as long as a year.

Lithium-ion batteries have a very bad feature is that lithium-ion battery aging (or aging, foreigners known as aging), is a lithium-ion battery in storage for some time, even without the use of recycled will be a permanent part of its capacity loss, because the lithium-ion battery anode and cathode material from a factory has already begun its failure in history. Different saturation temperature and battery charge status, the consequences of its timeliness difference, the following is a test data from the network in order to The percentage of capacity DELL 08K8194 Battery listed in:

Storage temperature - 40% state of charge ------- 100% state of charge

0 degrees ------- 98% (one year later )----- 94% (one year later)

25 degrees ------ 96% (one year later )----- 80% (one year later)

40 degrees ------ 85% (one year later )----- 65% (one year later)

60 degrees ------ 75% (a year later )----- 60% (3 months later)

So, can there be used for the first battery manufacturer's suggested is best for 3 to 5 times full charge-discharge process in order to eliminate electrode materials passivation, to reach maximum capacity.

Intended to replace the battery if a friend you had better look at the date of manufacture of the battery IBM 92P1087 Battery!

Original laptop notebook batteries and made the gap between how much?

Original laptop notebook batteries and made the gap between how much?

Today, the Internet saw an article! On the original IBM laptop battery Laptop Battery and domestic differences in contrast, feel very good! Dismantling process is quite detailed! The following is the original author of the summary of this experiment: deep thought, and nature needs to replace laptop batteries friends need attention:

"Compatible with the battery and do not legendary so bad, and even give people a lot of surprises, either shell or a control circuit is not lost on the original battery, and even batteries is also a slightly better than the original (hopefully not all of IBM have B-type batteries). and from the price comparison, an original IBM 9-cell battery customer service offer is 1,600 yuan, GodMobi of the piece only to be 400 yuan, the same one-year warranty is the replacement in March. cost-effective than the original much higher. "

The following is the original author: belongs to original author!

Under normal circumstances, laptop battery IBM 92P1089 Battery charge-discharge properties of 300 times it will be significantly decreased, but many people prefer to buy expensive original Service Center, an electronics market for batteries or batteries nor dares to buy is compatible with the battery.

I have friends around is the case, asked him why, answer is: fear of trouble. Laptops are not cheap, in the original customer to buy the rest assured, even for cores, but also be able to see him standing on the side of operation, and will not a change in the "black batteries; but to buy third-party production of batteries, can not turn to see what is batteries, really do not worry ... ...



This is a very typical answer, if low-quality batteries hurt because they have bought from his beloved books even give rise to security incidents is indeed a depressing question. IBM will be completely disassembled that this is an original battery and one domestic brand GodMobi batteries, with facts to speak, to see if production is now compatible with third-party IBM 92P1101 Battery vendors like how the battery in the end. At the same time, we will also interspersed in the text tell us about the basic knowledge of cells and circuits specifically dedicated to love it-yourself DIY classmates.



About to be dismembered two batteries, IBM and GodMobi original 6-pin compatible with 9-cell battery.

Prior preparation, two batteries, wallpaper knife 2, the word screwdriver 1, pry pieces 1.

All ready, now hands-on demolition!

Will be the first to be mutilated original IBM battery, to emphasize that this dismantling of destructive testing, do not imitate.



Battery Neice is the place where the largest gaps, and there is no alignment, and we began to disassemble it from here.





Here with the wallpaper knife in gently tilt the can, careful not to draw too IBM 08K8192 Battery deeply, so as not to hurt the batteries.

 

In Neice loose with the word screwdriver forced open after the lateral border.



From here, pry out the battery case with great difficulty to open.

Cover is now lifted the state, we can see that this piece of the battery 6 batteries and control circuitry arranged look. In accordance with the battery medium classification, they belong to lithium-ion battery. With a light weight, large capacity, no memory effect and so on.



Because the lithium-ion battery is almost no "memory effect" and does not contain toxic substances, etc., and now most of the many digital devices are used lithium-ion batteries for power supply, its price is relatively moderate, the energy density is high, its capacity is with the weight of the nickel-metal hydride batteries 1.5-2 times, but also has very low self-discharge rate.

The battery is also a piece of the more common structure: laptop battery box looks a thing, in fact, which is several "power core" formed by series-parallel, in general, have IBM 08K8193 Battery adopted laptop battery 18650 or 17670 batteries , mainly because the two larger capacity batteries, are smaller and are likely to cause the battery needed shape. We are now apart of the IBM battery is 18650, of which 18 representatives of diameter of 18mm, 65 on behalf of a high degree of 65mm, Sanyo products.

Here a small inconspicuous piece of circuit board in the entire laptop power supply system used to do play a vital. Because the lithium-ion batteries are basically 3.6V or so, two batteries in series to double voltage; parallel voltage unchanged, but the capacity has changed twice. For example IBM T series, capacity 4400mAh, voltage is 10.8V, the two values is the string from the six batteries and a combination.

Laptop battery charging are generally the first constant current, after constant pressure, internal with charging protection and full of light after changing tips, this is the charger and battery control circuit in the work of (different brands mechanism different).

For example a nominal 10V, less than begin to charge IBM 08K8195 Battery after full charge will no longer reach 10V; analogy up, this process is like a person to eat, eat after the stomach and nerves of the brain will be fed back to signal to stop eating, but if the measured are not allowed, there is no feeling of saturation would have been eating, with predictable results ... ...

Control circuitry on the main parts of a master chip, IBM's piece of the circuit structure in which we do not know, but look at solder joint appearance is very neat, original quality is not bad.

The circuit board with colorful strokes of the four color-coded, it should be electric core cable lines in the circuit board order.

The following is the batteries of the "joints", IBM in this solder joint is quite a neat, well-deserved maker's workmanship.

If you go to e-marketplace for their own batteries for batteries (that is, the original battery pack to replace the batteries out other batteries) batteries in general in addition to paying the money we have to pay 10 yuan for each solder joint around. Do not think for batteries, such as a change to your Walkman batteries that simple. In fact, changing batteries, battery manufacturers are strictly prohibited acts, because it has a very high risk. Changing batteries when the battery itself, with a voltage soldering iron or other tool to easily generate electrostatic discharge lead to short-circuit, causing fire IBM 08K8214 Battery explosion. On the other hand, due to charging protection circuit has been written into the original batteries information (capacity, discharge curve, etc.), changing batteries is likely to result in failure protection circuit, which can not be charged, or even lead to overcharging explosion. So, for batteries is dangerous, and there is a risk, it must pay attention!

In these erythroderma 18650 battery, we can only see some vague type of information.

It turns out that batteries How many pieces of information is not written on the skin, but rather printed on the batteries on the metal chamber, cut open the skin to see.

Sorry about that, although the Sanyo is the batteries inside is a better brand, but the piece of IBM original equipment batteries, only used Class B batteries.

Author that they have a licensed IBM T42, along with Taiwan and Japan brought back a Fujitsu laptop, almost the same time purchase, frequency of use is also similar, but a year later, IBM is very severe decline in battery performance, while Fujitsu, the battery performance and newly purchased When compared with almost unchanged.

Class B batteries, it is probably the answer to this IBM 92P1060 Battery situation, perhaps that "the best is only available for domestic use" rumor is true.

Well, IBM battery internal structure that we have seen very clearly in the following we begin dismantling GodMobi compatible battery.

Demolition, have to tear up the battery and so on around the bar.



Surprisingly, this bar battery GodMobi anti-tearing and it seems that the level of domestic manufacturers are also good to download oh.



From here, with the wallpaper knife forced open a gap, then use pry tablets (phone card is also OK) card here.

Go to the other side, or use the edge of the word screwdriver forced open.

Because it is 9-pin, so we can see here GodMobi battery than the above split off a row of IBM battery more batteries, similar to other structures.

Because the lithium-ion batteries have a certain charge voltage limit, the general 3.6v rechargeable battery should not exceed 4.2v, otherwise an explosion may be overheating. No matter what kind of notebook batteries by batteries + charging protection circuit, the charging protection circuit is again the control chip to prevent over-charging the battery IBM FRU 08K8193 Battery overheating and to prevent overheating protector formed. This is even GodMobi battery is no exception.

From the exterior, it and IBM's circuit structure is similar to formation of solder joints equally belong to welding machines.



Another piece of circuit board role: monitoring charging voltage, in approaching the threshold when to stop discharging, batteries have discharge limits, the general 3.6v battery can not discharge more than 2.75v, which would otherwise cause the battery failure, which is what we often say "over-discharge."

Let's look at GodMobi solder joints on batteries, it is certainly not original IBM battery so smooth, but also quite good, at least for batteries than the stronger hand joints too much.

By the way, change batteries while saving money, but the hidden danger IBM ThinkPad R51 Battery is not small. Such as charging protection circuit may be memories forward to your battery is full charge, even with no electricity for the new batteries, the circuit does not allow re-charging, and many of the core after changing the battery does not charge for that reason.

In addition, changing batteries, carefully check the batteries prior to the model, capacity, brand, sometimes different brands of batteries into the charging circuit, the circuit will automatically lock (Japan developed technology), resulting in failure for the core. Mo face a significant loss to gain petty advantages.

GodMobi on batteries is Samsung's 18650, purple, marked ICR18650-26, in front of a model, followed by 26, said single-capacity 2600mAh, can be regarded as one of Samsung's the best batteries.

On-line, can easily be found on the batteries to the information;

Name: Samsung Li-ion rechargeable battery

Model: SAMSUNG ICR18650-26

Nominal Capacity: 2600mAh

Nominal Voltage: 3.7V

Diameter: 18.25mm

Height: 65.00mm

Weight: 50g

Density: 520Wh / I, 199Wh/kg

Charging method: constant current constant voltage (4.2V)

Maximum charge current: 1CmA (2400mA)

Maximum discharge current: 2CmA (4800mA)

Discharge Temperature: -20 ° C ~ +60 ° C

Charging time: 3hrs (Standard) or 2.5hrs (Rapid)

Resistance of less than 65 milli-Europe

It should be said, though South Korea's production of batteries is not great influence on Japanese products, Samsung, Sanyo IBM ThinkPad R50 Battery is not as well known, but the comparison, at least Samsung's top batteries type B compared with Sanyo batteries to be much better.

Finally, compare the two battery shell.

From the side view, both are 1.2 mm thick shell around the memory is accompanied by a small amount of adhesive so that the fixed batteries, plastic parts from the materials to hand are feeling similar.

After describing the main parts, this is temporarily dismantling trials come to an end.

Open the point of view, is compatible with the battery is not legendary so bad, and even give people a lot of surprises, either shell or a control circuit is not lost on the original battery, and even batteries is also a slightly better than the original (hope not IBM is using all of the Class B batteries). And from the price comparison, an original IBM 9-cell battery customer service offer is 1,600 yuan, GodMobi of the piece only to be 400 yuan, the same one-year warranty is the replacement in March. Much higher than the original price.

Therefore, unless you have a strong plot and the original IBM IBM ThinkPad T43 Battery pockets enough, otherwise it is recommended to buy compatible batteries, sufficient for most everyday use. As for batteries, this paper has said its drawbacks, the love of their own choice

Batteries and Environmental Protection

Batteries and Environmental Protection

Potential contamination of used batteries has caused widespread concern in the community Laptop Battery. China is the world's number one dry battery producing and consuming nations, our data show that China currently has more than 1,400 battery manufacturers in 1980, the production of dry batteries volume has surpassed the United States and the largest in the world first. In 1998 the production of dry batteries in China amounted to 14 billion, while the same year the world's total production of dry batteries is about 30 billion.

Such a large quantity of batteries, making a big problem exposed, that is, how to make so many batteries do not undermine the pollution of our environment. According to our survey, used batteries containing heavy metals as well as the waste acid, waste alkali and other electrolyte solution. If you arbitrarily discarded batteries will destroy the corruption of the water, erosion of our survival crops and land, our environment is facing a huge threat. If the one on the 1st cell in the ground and rotting, it's toxic substances make one square meter of land to lose value; throw a coin battery into the water, which Fujitsu FPCBP63 Battery contains toxic substances which killed more than 60 million liters of water body pollution , equivalent to a person's life, water; used batteries containing heavy metals cadmium, lead, mercury, nickel, zinc, manganese, etc., in which cadmium, lead, mercury is a great harm to human body substances. The nickel, zinc and other metal although to a certain range of concentration is a useful material, but in the environment over the limit, but will also harm the human body. Waste batteries leaking heavy metals can cause rivers, lakes, sea and other bodies of water pollution, endangering the survival of aquatic and water use, an indirect threat to human health. Waste acid, waste alkali and so on could contaminate the electrolyte solution, so that land acidification and salinization, which decker around us like a time bomb. Therefore, the collection and disposal of used batteries is very important, if disposed of improperly, may be on the ecological environment and human health, cause serious harm. Randomly discard used batteries is not only pollute the environment, is also a waste of resources. Some people forget an account to the Fujitsu FPCBP68 Battery country's annual production of 10 billion batteries, annual consumption of 156,000 tons of zinc, 226,000 tons of manganese dioxide, 2080 tons of copper, 27,000 tons of zinc chloride, 79,000 tons ammonium chloride, 4.3 million tons of carbon rod. Despite the advanced technology has given us the right direction, but the phenomenon of pollution in China's battery is still not optimistic. Most of China's current domestic waste has been mixed with used batteries together into the ground, over time, after the battery into decay, heavy metal leaching, both could contaminate groundwater bodies, they could contaminate soil and finally through a variety of ways to enter the human food chain. Biological uptake of heavy metals from the environment through the food chain biomagnification, grade by grade in the higher organisms tens of thousands of times more enriched in, and then enter the human body through the food chain, and in some organs savings cause chronic poisoning, Japan Minamata disease is a typical case of mercury poisoning.

Batteries are generally divided into disposable batteries and rechargeable batteries. The main disposable batteries, including zinc-manganese batteries (zinc and manganese dioxide), zinc mercury batteries (zinc and mercury oxide) and lithium batteries and other several categories. The main rechargeable batteries include cadmium - nickel, iron - nickel, zinc - silver, zinc - air and lithium - iron sulfide and lead-acid batteries and so on. Our daily life is the most frequently used zinc-manganese batteries and zinc-mercury batteries, leaving the battery pollution is mainly caused by Fujitsu FPCBP77 Battery mercury (Hg) and cadmium (Cd).

Mercury toxicity

Mercury, which are commonly called "mercury" is a liquid at room temperature the material, can prevent the battery in the cathode zinc oxide, this approach to improve the storage life of the battery. Thus, as early as in the previous zinc used in batteries to do extremely overcast almost all do a certain amount of mercury preservative. However, the chemical combination of mercury and mercury have the neurotoxicity of endocrine system, immune system, also have an adverse effect, it will trigger people's slurred speech, unsteady gait, limb paralysis, leading to generalized convulsions, mental disorders and died.

For a long time, China in the production of dry Fujitsu FPCBP80 Battery batteries, it is necessary to join a toxic substance - mercury or mercury compounds. China's mercury in alkaline batteries up to 1% ~ 5%, 0.025% neutral dry-cell batteries, dry batteries every year for the production of dozens of tons of mercury amounted to much. As technology advances, the battery began to implement a low mercury and mercury-free, mercury substitutes Forafac fluorinated polymer surfactants in preventing the corrosion of zinc has achieved good results.

Discarded mercury batteries in nature will slowly overflow from the battery into the soil or water, and then under the action of microorganisms, inorganic mercury can be transformed into methylmercury, gathered in the fish's body, the human consumption of such fish , the methylmercury enters the human brain cells, people's nervous systems were severely damaged, in serious cases would be crazy to death. Well-known Minamata disease in Japan is caused by methylmercury.

Cadmium Toxicity

Cadmium is not a trace element necessary for the human Toshiba Satellite 2100 Battery body, the body of newborn babies, and there is no cadmium, but increased with age, and gradually accumulated. Cadmium with renal toxicity, which caused kidney damage is irreversible. At the same time after renal injury may also be secondary osteoporosis, osteomalacia and fractures. In 1993, the International Union Against Cancer will be set at IA level carcinogen cadmium. For these reasons, many developed countries have recommended a ban on the use of nickel-cadmium batteries and nickel-metal hydride battery has been replaced by nickel-cadmium batteries, avoiding the use of cadmium. In China, the vast majority of battery manufacturers are still using cadmium as raw material for production of the battery, making the battery further increase the dangers. Affected by long-term consumption of cadmium contaminated water and food, can lead to bone pain and disease, cadmium into the body, causing osteomalacia skeletal deformities, and in severe form of natural fractures, and even die.

Manganese toxicity

Excessive levels of manganese accumulation in the body can cause neurological dysfunction, an early manifestation of an integrated sexual dysfunction, the emergence Toshiba Satellite A65 Battery of heavier speech monotonous, dull expression, emotional indifference, accompanied by psychological symptoms.

Lead toxicity

Lead a major role in the nervous system, hematopoietic system, digestive system, and liver, kidney and other organs, can inhibit the synthesis of hemoglobin metabolism, but also directly on the mature red blood cells, for infants, young children much, it will lead to children's physical development retardation, chronic lead in the prime of childhood mental retardation.

Nickel toxicity

Nickel powder dissolved in the blood, to participate in the body circulation, with strong toxicity, can damage the central nervous system, causing abnormal blood vessels, severe cases lead to cancer.

Zinc toxicity

Zinc is an essential element of the Toshiba Satellite A60-662 Battery human body, less toxic, oral zinc sulfate 1000mg only people with acute poisoning, but the inhalation of zinc oxide dust can cause poisoning. Its symptoms are generalized fatigue, muscle pain, difficulty breathing, vomiting, diarrhea, severe heart weakness, prostration, convulsions died. Zinc sulfate, zinc chloride penetrated the skin mucous membrane, it can produce dermatitis and ulcers. Of zinc to fish and aquatic toxicity of the toxic than the people, so the water quality requirements for fishing in the water content of zinc per liter should not exceed 0.1mg.

Recycling of waste batteries

Waste batteries may be small, against Queshen big. However, due to pollution, waste batteries do not like waste, air and water pollution, as could any sensory feel it has great hidden, so did not receive due attention. At present, China's battery production and consumption to become a big country, and used batteries pollution is an urgent need to address a major environmental Toshiba Satellite 1900 Battery problem.

According to environmental experts, in the recovery of waste batteries per 1,000 grams of metal, of which there are 82 grams of mercury, 88 grams cadmium, can be said that disposal of waste batteries recycling is not only addressed the sources of pollution, but also achieve the recycling of resources. In developed countries the recycling of spent batteries and use very seriously. Many countries in Western Europe, not only in stores, but also directly on the street are equipped with a special battery recycling box, and used batteries are 95% of the material can be recycled, particularly in high-value metal recovery. Such as the Foreign Secondary Lead industry developed rapidly, the current lead 55% of all production comes from regenerated lead. The Secondary Lead Industry in dealing with the regeneration of waste lead-acid batteries account for a substantial portion. 100 kg of waste lead-acid batteries can be recycled 50 to 60 kilograms of lead. Cadmium batteries for the regeneration of waste treatment technology abroad, have been more mature to deal with 100 kilograms of cadmium battery scrap recycling about 20 kg of metal cadmium, mercury batteries Toshiba Tecra 9100 Battery are mainly used for the environmentally sound processing means to prevent the pollution of the environment . However, there are in this area of management rather weak.
