What is the performance of Lithium ion battery?

High energy density;

High operation voltage;

No memory accumulation;

Long cycle life;

No pollution;

Light weight;

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.
