Which factory is better

Lithium batteries are divided into lithium batteries and lithium ion batteries. Cell phones and laptops use lithium-ion batteries, commonly known as lithium batteries. Batteries generally use lithium-containing materials as electrodes and are representative of modern high-performance batteries. Real lithium batteries are rarely used in everyday electronics because of their high risk.

The positive electrode materials of the lithium battery are lithium cobalt oxide LiCoO2, ternary material Ni + Mn + Co, lithium manganese oxide LiMn2O4 plus conductive agent and binder, coated on aluminum foil to form a positive electrode, and the negative electrode is layered graphite. The conductive agent and adhesive are coated on the copper foil. The more advanced negative lamellar graphite particles have adopted Nano carbon.

1, pulp: with a special solvent and binder, respectively, mixed with powder positive and negative polar active substances, after stirring evenly, to form a serrated positive and negative substance.

2, coating film: through the automatic coating machine, the positive and negative polar slurry is evenly coated on the surface of the metal foil, and after automatic drying, the positive and negative polar plates are automatically cut.

3, assembly: according to the positive electrode-diaphragm-negative electrode-diaphragm from top to bottom by winding into the electrolyte, seal, positive and negative ear welding and other process, that is, complete the battery assembly process, into a finished battery.

4, into: the finished battery placed in the test cabinet for charging and discharging tests, screening out qualified finished batteries, to be delivered.
