What is a polymer battery?
Polymer battery, also known as li-polymer. It is also a kind of lithium-ion battery, but compared with liquid lithium battery, it has many obvious advantages such as high energy density, miniaturization, ultra-thinness, light weight and high safety, and it is a new type of battery.

In appearance, lithium polymer batteries have ultra-thin characteristics, and can be made into batteries of any shape and capacity to meet the needs of various products. The minimum thickness of this battery can reach 0.5 mm, and its nominal voltage, like lithium ion, is 3.7V without memory effect.
