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.

As we know, the lithium battery named by 6 digits, indicating thickness, width and length. At this page, it is HLC804050. It indicates of lithium polymer battery of thickness of 8.0mm, a width of 40mm, and length of 50mm. 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.
We can produce from 100mAh to 3000mAh lipo batteries with different dimensions. It uses soft aluminum-plastic composite packaging film. The interior is a semi-solid polymer. The performance is stable in discharge, high in efficiency and small in internal resistance. The safety performance is good, and there are overcurrent and overvoltage protection devices. The service life is about 500 charge-discharge cycles.
Before delivering batteries, we will do all safety performance tests as follows:
Forbid Disassemble Batteries
The battery has protective component and circuit internally to avoid danger. Improper disassembly will destroy its protective function and make it heat, smoke, distort or burn.
Forbid Short-circuit Batteries
Do not touch the plus and minus contacts with metals. Do not put the battery with metal element together in either storage or movement. If the battery is short-circuit, it carries magnified current, which will cause damage and make the battery heat, smoke, distort or burn.
Forbid heat and burn the battery
Heating or burning the battery, it will cause the isolated element in the battery dissolved, the protection function stopped or the electrode burned. Overheating will make the battery heat, smoke, distort or burn.
To avoid use the battery near the heat
Do not use the battery near the fire and stove, or over 80oC. Overheating will cause the battery internal short-circuit and make it heat, smoke, distort or burn.
Forbid bathing the battery
Do not dampen the battery, or even immerse it in the water, which will cause internal protection circuit and its function lost or abnormal chemical reactions, which will lead to heating, smoking, distortion or burning.
Avoid charging near fire or in the sunlight
Otherwise, it will cause internal protection circuit and its function lost or abnormal chemical reactions, which will lead to heating, smoking, distortion or burning.
Danger in using non-indicated chargers in
Charging in abnormal condition, the battery will cause internal protection circuit and its function lost or abnormal chemical reactions, which will lead to heating, smoking, distortion or burning.
