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.

Battery Features:

Most ‘lithium’ home storage batteries use the LFP chemistry for reasons of cost and fire safety. The lower energy density than other lithium chemistries is not significant in this static application.

The cycle life is long, generally up to 1500 times or even 2000 times.

Good safety performance, no pollution, no memory effect. As the predecessor of Li-ion, the lifepo4 battery is prone to short circuit of dendrites due to metal lithium, which reduces its application fields: Li-ion does not contain cadmium, lead, mercury, and other elements that pollute the environment.

The self-discharge is small, and the self-discharge rate of Li-ion fully charged at room temperature for one year is about 10%
