The technology of lithium ion battery is very strict and complicated. Only a few main processes are briefly introduced here.
(1) Pulping
Special solvent and adhesive are used to mix the positive and negative active substances with powder, and the slurry positive and negative active substances are prepared after high speed stirring.
(2) Coating film
The paste will be made evenly coated on the surface of the metal foil, drying, respectively made of anode and cathode pieces.
(3) Assembly
According to the positive plate - diaphragm - negative plate - diaphragm from top to bottom, through winding into the battery core, and then through the injection of electrolyte, sealing and other technological processes, that is, to complete the assembly process of the battery, made into a finished battery.
(4) To turn into.
The finished batteries are tested with special battery charging and discharging equipment, and each battery is tested, and qualified finished batteries are screened out for delivery.
