What is the performance of Lithium ion battery?
High energy density;
High operation voltage;
No memory accumulation;
Long cycle life;
Very low self-discharge rate.
What is the performance of Polymer Lithium ion battery?
No liquid electrolyte, so never leak;
Can be made into various shape;
Can be made into thin battery, such as 3.6V, 400mAh, the thickness can decrease to 0.5mm;
High voltage in an battery: several battery with liquid electrolyte can be connected in series to get a high voltage only; the Li-polymer battery can get high voltage in an cell through multiplayer combination;
Same volume Li-polymer batteries` capacity is two times of Li-ion battery.
