subject: Rechargeable Batteries Are Significantly More Complicated To Design Than A Non-rechargeable Battery [print this page]


Domestic battery manufacturers supporting electrolyte has been basically achieved domestically. Main raw materials for the electrolyte of 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%, however, the market power basically Kanto chemical industry, SUTERAKEMIFA, Morita chemistry, several Japanese companies a monopoly. Therefore, the urgent need to solve the most critical lithium electrolyte lithium hexafluorophosphate electrolyte composition (LiPF6) large-scale production problems. Only the key technology breakthroughs, China's vehicle power lithium battery industry chain to close to perfect. Laptop Battery Laptop Battery Laptop Battery Laptop Battery Laptop Battery

Now the world market supply and demand balance electrolyte lithium battery, lithium battery electrolyte requirements on a high, CANON BP-511A battery SONY NP-FT1 battery but the amount was very small. Such as a mobile phone battery with only 3 grams, the proportion is small, the electrolyte for the production of 2,000 tons of 600 million cell phone batteries. Car battery can not be the same, a car is necessary to 40 kg. Once the emergence of electric vehicles, will bring explosive growth in the electrolyte.

Domestic enterprises engaged in the production of lithium battery electrolyte are Juhua, Shanshangufen, Huarong Chemical, Zhuhai race Wei Electronics, Tianjin Taurus, Shantou golden light, such as Guangzhou, heaven-sent more than 10. Among them, the Huarong Chemical Co., Zhuhai race Wei electronic positioning high-end market, other companies can only do low-end market.

At present, few businesses can produce lithium hexafluorophosphate, in this one Juhuagufen walk in the forefront of domestic enterprises, have a comprehensive fluorine chemical industrial chain, advanced technology and rich fluoride fluoride chemical raw materials. Production of raw materials of lithium hexafluorophosphate anhydrous hydrogen fluoride, will be the development of a leader, is of Jiangsu Guotai, Shanshangufen electrolyte lithium battery manufacturers and other upstream industry, the outlook is very wide, it is worth focusing on.

4. Diaphragm:

Li Sheng-mao believe that with the gradual promotion of new energy vehicles,SONY NP-FC10 Battery dell Inspiron 1501 battery the future demand of power lithium battery materials would be detonated. Department of lithium material diaphragm highest technical barriers to a high value-added materials, usually over 70% gross profit margin, accounting for 20-30% of the cost of lithium batteries. In accordance with the terms, a car can be used from 1000 to 2000 square meters of membrane. Divide the market is currently a serious shortage of supply, most dependent on imports, the market dominated by Japanese Asahi Chemical Industry, Tonen Chemical, and the United States Celgard control. Membrane with a typical "high-tech, high-capital" characteristics, and the project cycle is very long, risky investment, the investment enthusiasm of domestic enterprises is not high. Currently, the domestic energy production and membrane only star-source technology, Jinhui Tech two technologies are relatively mature.

Fosugufen (000973): In 2006, BYD Fosugufen jointly funded with $ 2,810,000, set up a photoelectric materials, Foshan City, Jinhui High-Tech Co., Ltd., which Fosugufen 55% of the shares. It is this company, and BYD will Fosugufen conceptual link up. Currently, the domestic annual demand is about 130 million square meters, and Jinhui 1200 the company made more than one million square meters. Nevertheless, 12 million square meters annually Jinhui membrane products for use in vehicle power batteries a little, and most of the communication or use batteries. Including sales to BYD membrane, and is mainly used in mobile phone lithium batteries. Financial data, Jinhui company established only three years, showing a substantial profit growth, 2008 has brought Fosugufen million profit in 2000.

Of up to shares (600,074): Fosugufen counterparts in the film King of shares is made. Up shares of major shareholders in the application of group technology innovation in the search for new breakthroughs, independent research and development of new materials, production of solar photovoltaic, battery separation film and a number of projects with international leading level Dell 75UYF Battery Dell Inspiron 1720 battery . Of shares in China's leading new materials, soft plastic polymer, producing BOPP films, BOPET film, CPP film three series of products, the leading domestic production scale,nikon CR-V3 battery but these are lower end products, many used for packaging material, and polyolefin film If used in lithium ion separator film, thin film solar cells, will be worth a hundred times, the shares reached a Fosugufen-like potential.

Alternative future of new energy vehicles will be the inevitable trend of conventional vehicles, power lithium batteries as a new energy vehicles, the "heart", will give rise to huge industrial economic effects on the battery raw material suppliers and vendors are huge commercial cake.

By 2012, annual production of new energy vehicles will reach 100 million units, according to the cost of each new energy 7 million automotive batteries, power lithium battery cathode material lithium iron phosphate 52 kg, 41 kg anode material, electrolyte 40 kg calculated . 1 million hybrid vehicles will drive the 52,000 tons cathode material, anode material 41,000 tons, 40,000 tons of electrolyte needs. For domestic battery manufacturers, this will be a total output value of 70 billion yuan of the big cake. If calculated by bus, this value will increase 3 times - each hybrid bus battery demand is 4 times the car.

Both plug-in hybrid or pure battery-powered cars,dell Latitude C640 battery Dell XPS M140 battery will use lithium batteries. However, the participation of lithium battery power into profitable enterprises to track I'm afraid to go to 2012, and the power lithium battery itself has some technical problems to solve. Today's sophisticated battery should be a nickel-hydrogen batteries.

Rechargeable batteries are significantly more complicated to design than a non-rechargeable battery because the electrochemical reaction that provides power must be reversible. As Lawrence Berkeley Lab's staff scientist Frank McLarnon explained to Scientific:

"When a battery is discharged, an electrochemical oxidation reaction proceeds at the negative electrode, and an electrochemical reduction reaction occurs at the positive electrode. When one attempts to recharge a laptop battery by reversing the direction of electric current flow, the opposite takes place: a reduction reaction proceeds at the negative electrode, and an oxidation reaction takes place at the positive electrode.Laptop BatteryACER Laptop Battery | Dell Laptop Battery | HP Laptop Battery | TOSHIBA Laptop Battery

"In the case of the rechargeable HP EliteBook 8530w battery , the electrochemical oxidation-reduction reactions are reversible at both electrodesIn the case of the non-rechargeable battery, when one attempts to recharge the battery by reversing the direction of electron current flow, at least one of the electrochemical oxidation-reduction reactions is not reversible. When the battery is charged, the overall reduction reaction that proceeds at the negative electrode may not be the true reverse of the oxidation reaction that proceeded when the battery was discharged.

If the laptop battery process isn't exact, then unwanted build up can take place on either terminal over time, which can cause a dangerous short-circuit.

Also unlike a household battery, laptop batteries are composed of multiple internal cells. These cells are arranged in series and in

parallel in such a way that the battery has a higher voltage level than the individual cells. Laptop batteries also contain a small circuit board that controls the way the cells are recharged. Without this board, the Dell Inspiron 1764 battery would not function properly.

Of course, the most obvious difference about laptop batteries is that their physical shape is different from the traditional cylindrical form of a AA, AAA or C battery. Laptop manufacturers custom design their laptop battery packs to conform with the overall functionality of the laptop model. Some laptops and their laptop batteries are engineered for their light weight and small size, others for their ability to replace the functionality of a desktop system. As a result, one size can't fit all in the world of laptop computers. This causes notebook battery to vary across different models.
