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 such as smart cards, trackers

and smart wearables, Lithium Polymer battery can provide a certain amount of electric energy to drive their functions

of signal transmission or data acquisition. And Lithium Polymer secondary battery allows charging and discharging

cycle, broadening the servicing life of electronics products.
