(1) No liquid electrolyte, so never leak; 
(2)Can be made into various shape; 
(3) Can be made into thin battery, such as 3.6V, 400mAh, the thickness can decrease to 0.5mm; 
(4) Battery is transmutable and can be crooked: the maximum angle is 900; 
(5)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; 
(6)Same volume Li-polymer batteries’ capacity is two times of Li-ion battery.
