The positive electrode material of lithium battery is lithium cobaltate LiCoO2, ternary material Ni+Mn+Co, lithium manganate LiMn2O4 plus conductive agent and binder, coated on aluminum foil to form positive electrode, negative electrode is layered graphite plus conductive agent and bonding The agent is coated on a copper foil base tape, and nanoporous carbon has been used for the relatively advanced negative-layered graphite particles.

1. Pulping: Mixing with a powdery positive and negative active material with a special solvent and a binder, and mixing them to form a slurry of positive and negative materials.

2. Coating film: The positive and negative electrodes are uniformly coated on the surface of the metal foil by an automatic coating machine, and automatically cut into positive and negative pole pieces after being automatically dried.

3. Assembling: According to the process of positive electrode sheet-separator-negative electrode sheet-separator from the top to bottom, the electrolyte is injected into the electrolyte, sealed, and the positive and negative electrodes are welded, that is, the assembly process of the battery is completed, and the finished battery is fabricated.

4. Chemicalization: Place the finished battery in the test cabinet for charging and discharging test, and screen out the qualified finished battery, waiting for delivery.
