Main Functions:

Lithium Polymer batteries make it possible for small objects to achieve intelligence. Bendable Lithium Polymer cells

open up new applications for lithium-ion batteries. For small, thin and flexible devices , Lithium Polymer battery can

provide a certain amount of electric energy to drive their functions of signal transmission or data acquisition. Such as

Police cameras.AndLithium Polymer secondary battery allows

charging and dischargingcycle, broadening the servicing life of electronics products.
