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.
