The Laptop Battery Is Composed Of Multiple Internal Cells
Just like their AA, AAA, and C cell cousins, laptop batteries create an electrochemical
reaction that forces a stream of electrons from one place to another. And just like household batteries, laptop battery have a positive and negative terminal where electrons are received and sent, respectively. However, have unique characteristics compared to household batteries.
1. They are rechargeable
2. The laptop battery is composed of multiple internal cells
3. They contain a small printed circuit board
4. Their overall shape of a laptop battery and the location of their terminals vary from model to model
Laptop Battery Laptop Battery Laptop Battery Laptop Battery Laptop BatteryRechargeable 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.
Compared with the cathode material, lithium battery anode materials accounted for the proportion of low cost, and the domestic industry has been achieved, the negative electrode materials, graphite, solid carbon-based. Currently engaged in the production of lithium battery cathode material, the top three companies is China's national security,sony NP-FM51 battery Shanshangufen, long sand sea capacity, the current negative electrode materials to meet the basic needs of the domestic market, but with the increasing popularity of new energy vehicles, the future market for this one demand will be a huge gap.

China Baoan (000009): Baoan, Shenzhen Bei Terui holding 55% of China's subsidiary, is the standard Li-ion battery carbon cathode materials makers. The capacity of carbon anode material is 6,000 tons / year, price is 60,000 yuan / ton, up to 80% market share, ranking second. Clients include Panasonic, Hitachi, Samsung, TCL, BYD more than 130 manufacturers. In 2008, Bei Terui the acquisition of Prudential Tianjin Railway Company, to carbon negative material costs decreased by 30%. Although business is booming subsidiary of battery materials, but limited by the overall size of the market, listed companies in China Baoan, contributions from the performance of battery materials is difficult to rely on. China Baoan main business is real estate and medicine, the first half of 2008 accounted for over 90% of revenue, including lithium, including other income accounted for less than 9%.
Shanshangufen (600,884): sony NP-F10 battery Bei Terui Shanshangufen is a great competitor. A subsidiary company, Shanghai Shanshan Science and Technology, 1,200 tons of production capacity anode material for lithium batteries - mesophase carbon microbeads (the CMS). CMS project is a national 863 high-tech Research and Development Program, was listed as the national high-tech industry demonstration projects. In recent years, the company's lithium-ion battery materials industry continues to show a trend of rapid development, including new products negative MG (microblogging) S, and FSN-1 in large-scale to the market to achieve a good sales performance. Currently, the CMS Shanshangufen of 10 million yuan per tonne, the annual capacity of 1,200 tons.
