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 batteries have always had the characteristics of self-discharge. If they are not used for a long time and are not charged for an intermediate period of time, the self-discharge will exhaust the battery power, resulting in the battery’s voltage being too low and unable to be charged. So, what should I do if the lithium battery cannot be charged? Let’s take a look.
