Polymer batteries generally consist of three elements: positive electrode, negative electrode, and electrolyte. The so-called lithium polymer battery refers to a battery system that uses polymer materials at least one or more of the three elements. In lithium polymer battery systems, most polymer materials are used on the positive electrode and electrolyte.

　　The positive electrode material uses conductive polymer or inorganic compounds commonly used in lithium-ion batteries, while the negative electrode often uses lithium metal or lithium carbon interlayer compounds. The electrolyte is a solid or colloidal polymer electrolyte or organic electrolyte. Due to the absence of excess electrolyte in the lithium polymer, it is more reliable and stable.

　　1. There is no battery leakage problem, and the battery does not contain liquid electrolyte inside, using colloidal solids.

　　2. Can be made into a thin battery: with a capacity of 3.6V 400mAh, its thickness can be as thin as 0.5mm.

　　3. Batteries can be designed into various shapes.

　　4. Battery can bend and deform: Polymer batteries can bend up to about 90 degrees.

　　5. Can be made into single high voltage: Liquid electrolyte batteries can only be connected in series with several batteries to obtain high voltage. Polymer batteries, due to their lack of liquid, can be made into multi-layer combinations within a single cell to achieve high voltage.

　　6. The capacity will be twice that of lithium-ion batteries of the same size.
