The production process of lithium ion battery pack: the battery core detection and matching group, according to the required voltage capacity and series. Install protective lines. Finished product inspection. Packing. Those are the procedures. The whole set of equipment and tools can be completed with about 20,000 RMB. Lithium-ion battery packaging technology is very strict and complex, here can only briefly analyze a few of the important processes:
Step 1. Special solvent and adhesive are used for pulping to mix with powdery positive and negative active substances respectively, and the slurred positive and negative substances are made after high-speed mixing.
Step 2, the film will be made of paste evenly coated on the surface of the metal foil, drying, respectively made of positive and negative pole sheet.
Step 3, assembly according to the positive plate - diaphragm - negative plate - diaphragm from top to bottom in the order, after winding into the battery electrode core, and then through the injection of electrolyte, sealing and other technological processes, that is to complete the battery assembly process, made into a finished battery.
Step 4. Huacheng uses special battery charging and discharging equipment to charge and discharge the finished battery, and tests each battery to screen out qualified finished lithium-ion battery packs for delivery.
