Lithium Battery Process Work Flow

We are a professional lithium battery factory in China. Now we briefly introduce how to produce lithium batteries. It starts from cathode & anode mixing, coating, baking, calendering, automatic slitting & cutting, winding, top & side sealing, electrolyte injection, pressing formation, forming, capacity grading, OCV1 & OVC2, cell to PCB, insulation and shipping. Welcome to contact and ask for the workflow table list.

Lithium battery specs:

As we know, the lithium battery named by 6 digits, indicating thickness, width and length. At this page, it is HLC902535. It indicates of lithium polymer battery of thickness of 9.0mm, a width of 25mm, and length of 35mm. The production process of lithium-ion polymer batteries generally adopts laminated flexible packaging, so the size change is very flexible and convenient, and there are relatively many models.


  1. Notice
    The battery shall be prevented to be exposed in effulgence so as not to cause over-heated, distort, smoke and weaken its performance and cycle life.
  2. Electro Static-free
    There is a protective circuit inside the battery to prevent contingency. Do not use the battery in the Electro static circumstances, (above 1000V), for it is easily destroyed the circuit board so that the battery doses not work and causes overheating, distortion, smoking or burning.

  3. Discharging Temperature Range
    Recommended discharging temperature range is 10~45oC, beyond which it will weaken the electrochemical performance of the battery and also shorten its cycle life.


  1. What’s the product warranty?
    1-year product warranty since batteries is sent out.
  2. When will you send samples?
    7~15 days after the datasheet is approved.
  3. What’s the MOQ?
    No MOQ limit. We can accept small trial orders.
  4. What testing will we do for customers?
    We will do protection for short-circuit, over-charge, over-discharge.
