The positive electrode materials of lithium batteries include lithium cobalt oxide LiCoO2, ternary materials Ni+Mn+Co, lithium manganate LiMn2O4 plus conductive agent and binder, which are coated on aluminum foil to form the positive electrode, and the negative electrode is layered graphite plus conductive agent and bonding The agent is painted on the copper foil base tape. The more advanced negative electrode layered graphite particles have adopted nano-carbon.
1. Pulping: Use a special solvent and a binder to mix with the powdered positive and negative active materials, and stir them evenly to make a slurry of positive and harmful elements.
2. Coating: The positive and negative electrode slurry is uniformly coated on the surface of the metal foil by an automatic coating machine, and the positive and negative pole pieces are automatically cut after automatic drying.
3. Assembling: according to the order of positive electrode sheet-diaphragm-negative electrode sheet-diaphragm from top to bottom, the electrolyte is injected, sealed, and the positive and negative lugs are welded to complete the battery assembly process to make a finished battery.
4. Formation: Put the finished battery in the test cabinet for charge and discharge test, screen out the qualified finished array and wait for it to leave the factory
