Lithium Polymer

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 applications that require thin geometries, such as batteries for cell phones, tablets, wearable technologies and other such applications. Expected cycle life is about 500+ full charge and discharge cycles.
