| Abstract: | Lithium ion rechargeable battery is developed based on the principle of lithium ion intercalation and deintercalation on a carbon negative electrode and an intercalation compound positive electrode. So far energy density of overseas 1865 type Li,C/LiPF6 - EC + DEC/Li1-x-CoO2 battery has reached 105 Wh/kg and 270Wh/L. Selfdischarge and cycle life of that are less than 12%/month and 1000 times at 100% DOD,1C rate respectively.The battery has been widely used in cellular phones,video cameras and note-book computers etc. It may be used as power sources for electrical vehicles in the future. |
