Our goal is to guide industry stakeholders, buyers, and partners to better understand the competitive landscape and benchmark manufacturers.

What is a Polymer Lithium Battery?

Polymer lithium batteries, commonly called lithium polymer (Li-Po) batteries, are a type of rechargeable battery distinguished by their use of a polymer electrolyte rather than a liquid electrolyte. This structural difference allows Li-Po batteries to be lightweight, thin, and flexible in design while providing high energy density, safety, and longer cycle life compared to traditional lithium-ion batteries.

The key advantages of polymer lithium batteries include:

• Lightweight and slim form factor, enabling compact device design

• Enhanced safety with reduced risk of leakage

• High energy density for longer runtimes or driving ranges

• Excellent flexibility enabling use in wearables and foldable devices

• Good thermal stability and cycle performance

Due to these qualities, polymer lithium batteries are increasingly adopted for smartphones, tablets, wearable gadgets, drones, electric vehicles (EVs), energy storage systems, and medical devices.
