Abstract��The lithium ion battery is the advanced battery developed at the beginning of 1990��s, it has high energy,high voltage,long life span ,free from pollution and has no memory effect. In the last years, extensive research on the 50 Ah cylinder lithium ion battery, including the electrode material,the electrode manufacturing process, electrolyte,diaphragm, coiling,welding and safety has been carried on .The developed capacity of battery is of 50 Ah, its specific energy exceed 147 Wh/kg, its discharging,short circuit,overcharging, pin pricking,electric charge storage, cycling life, energy storage are greatly improved.This kind of high capacity lithium ion battery are mainly used for a power of an underwater weapon . It will also be used in the field such as electric automobile and aerospace. It is a kind of promising battery.
