Why choose lithium polymer battery?

  1. High working voltage, nominal voltage 3.7V.
  2. High energy density. Approximately 6-7 times of lead-acid batteries.
  3. Low self-discharge rate
  4. No memory effect
  5. Support size customization
  6. Custom capacity from 100Ah to 3000Ah.
  7. Lightweight. the same volume of lead-acid battery products is about 1/5
  8. Long lifespan over 500 cycles
  9. Compared with traditional battery technology, lithium-ion batteries charge faster and last longer, and higher power density can achieve longer battery life while being lighter.

What are application of lithium pouch batteries?

Most of the current polymer batteries are soft pack batteries, using aluminum plastic film as the outer shell. When the organic electrolyte is used inside, the liquid will not explode even if the liquid is hot. Because the aluminum plastic film polymer battery adopts solid or gel state without leakage, but expansion. In terms of shaping, polymer batteries can be thinner, arbitrarily shaped and arbitrarily shaped. Therefore, polymer lithium batteries are widely welcomed by various manufacturers.

Lithium Polymer Battery Manufacture Process


To understand the real demands of the lithium polymer battery, you need to provide the lithium battery size, electrical performance requirements, output requirements, and functional requirements.

Quick Response

Evaluate a solution and quote the known parameters provided by the customer, also provide full datasheet for reference.


After the customer’s approval, we will start to make samples for polymer batteries, and provide charging and discharging cycle curve and data.

Sample Test

Assist and track customer test results, as well as customer’s overall equipment operation effect.

Certificate Proceed

We will discuss with customer certificate works based on the final country and applicate requests. It may be MSDS, UN38.3, IEC62133, KC, PSE, etc.

Mass Production

Develop process documents and BOM sheet, purchase materials, arrange staff production, quality personnel monitoring, and random inspection, and package and shipment.
