Features
Polymer Lithium-ion Batteries employ the Laminated Aluminum Foil as battery case, which is lighter, thinner, more flexible and safer. The advantages of Polymer Lithium-ion Batteries are listed as followings:
- Built-in protection circuit PCM for avoid over-charging,over-discharging.
- Flexible form factor - manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.
- Lightweight - gelled electrolytes enable simplified packaging by eliminating the metal shell.
- Improved safety - more resistant to overcharge; less chance for electrolyte leakage.
- High-operating voltage, large starting up power
- High-energy density
- Long life cycle, more than 600 charge/discharge cycles (80% capacity remained)
- Minimal self-discharge, less than 10% monthly
