Lithium-ion polymer batteries have technologically evolved from lithium-ion batteries and have comparable energy density to lithium ion batteries. Today, demand is rising for lightweight and thin portable device. Similarly, there is a demand for a thin, lightweight battery for these applications. Lithium-ion polymer batteries are developed for this purpose.
More thinner and more lighter - -By using a super-light laminated aluminum film for the external packaging, lithium polymer batteries are suitable for all applications where weight, size, and durability are critical factors.
Flexible form factor - With high volume, any reasonable size can be produced economically.
Improved safety - more resistant to overcharge; less chance for electrolyte leakage
