What Are The Production Process Steps Of Lithium-ion Batteries?

The positive electrode materials of lithium batteries include lithium cobalt oxide LiCoO2, ternary material Ni+Mn+Co, lithium manganese oxide LiMn2O4 with conductive agent and adhesive, which are coated on aluminum foil to form the positive electrode. The negative electrode is layered graphite with conductive agent and adhesive coated on the copper foil substrate. The more advanced negative electrode layered graphite particles have been used with nano carbon.
1. Pulping: Mix specialized solvents and binders with powdered positive and negative polar active substances, stir evenly, and make a paste like positive and negative polar substance.
2. Coating: By using an automatic coating machine, the positive and negative electrode slurry is evenly coated on the surface of the metal foil, and after automatic drying, it is automatically cut into positive and negative electrode plates.
3. Assembly: Complete the assembly process of the battery by winding and injecting electrolyte, sealing, and welding the positive and negative electrode ears in the order of positive electrode plate diaphragm negative electrode plate diaphragm from top to bottom, and produce the finished battery.
4. Transformation: Place the finished battery in a testing cabinet for charging and discharging testing, select qualified finished batteries, and wait for delivery.
