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:

• Very low profile - batteries resembling the profile of a credit card are feasible: cell thickness measuring as little as one millimeter (0.039 inches).
• 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
• UL,CE certified
