Lithium Polymer Ion batteries provide the performance of the Li-ion in a thin or moldable package. They do not use a volatile liquid electrolyte and can sustain significant abuse without explosion or fire.
The lithium polymer uses a polymer gel electrolyte to replace the traditional liquid electrolyte. Lithium-polymer finds its market niche in wafer-thin geometries, such as batteries for credit cards and other such applications. Expected cycle life is about 1000+ cycles. 

Key Features:
High energy density, high and stable operating voltage, with average voltage over 3.7V.
High safety, no fire, no explosion.
Long cycle life 1000 times.
Battery can be designed into different shapes and sizes.
Customized designs are available，with thickness from 2 to 10mm, capacity from 20 to 25000mAh.
Note: Characteristics can change according to improvements in chemistry or special niche requirements.
