Lithium battery production process:

　　The first step--preparation of electrode slurry

　　It is mainly to mix electrode active materials, binders, solvents, etc. together, stir and disperse sufficiently to form a slurry.

　　The second step-coating

　　The slurry prepared in the first step is uniformly coated on the current collector (aluminum foil or copper foil, etc.) with a specified thickness, and the solvent is dried.

　　The third step-pole piece punching

　　Punch the pole piece produced in the previous step into the specified size and shape.

　　The fourth step-stacking

　　Assemble the positive and negative plates and the separator together, and form the pole core after the glue is applied.

　　Step 5-Assemble the soft pack battery

　　Put the pole core produced in the previous step into the aluminum-plastic film that has been flushed, and complete the top seal, side seal, etc. (and leave a mouth for injection) to form a soft pack battery without injection.

　　The sixth step-injection

　　Inject a specified amount of electrolyte into the soft-pack battery cell. Of course, the battery cell needs to be baked, and the liquid injection operation is carried out in a low humidity environment, too much moisture content is not good.

　　Step 7-battery sealing

　　The gas inside the cell is drawn out and sealed in a vacuum environment.
