How about the production process of lithium ion batteries?

The cathode 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 coated on the copper foil base tape, and 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 negative materials.

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 electrodes are automatically cut into positive and negative pole pieces after automatic drying.

3. Assembly: According to the top-down sequence of positive electrode sheet-diaphragm-negative electrode sheet-diaphragm, the electrolyte is injected, sealed, and the positive and negative lugs are welded to complete the assembly process of the battery 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 battery, and wait for it to leave the factory.
