Fabrication Technology Of Lithium-ion Battery

- Jan 31, 2018-

The cathode material of lithium battery has cobalt acid lithium LiCoO2, ternary material Ni+mn+co, manganese acid lithium LiMn2O4 plus conductive agent and adhesive, coating on aluminum foil to form positive electrode, anode is layered graphite plus conductive agent and adhesive coating on copper foil base belt.

1. Pulping: With a special solvent and binder, respectively, and powder-like positive and negative polar active substances mixed, after mixing evenly, made slurry-like positive and negative polar matter.

2. Coating: Through the automatic coating machine will be positive and negative polar slurry coating evenly on the surface of metal foil, after automatic drying automatically cut into positive and negative pole piece.

3. Assembly: According to the positive plate-diaphragm-negative film-the diaphragm from top to bottom of the sequence of the injection of electrolyte, sealing, positive and negative ear welding process, that is, complete the battery assembly process, made of finished battery.

4. Into: The finished battery placement test cabinets for charge and discharge testing, screening qualified finished battery, to be manufactured.
