Production process of lithium-ion battery soft pack cells:
Soft-packed lithium batteries are thermally packaged, while metal shell batteries are generally welded (laser welding). The reason why soft-pack batteries can be thermally sealed is that they use aluminum-plastic packaging film.
The first step-preparation of electrode paste
The important thing is to mix electrode active materials, binders, solvents, etc., and stir and disperse them thoroughly to form a slurry;
Step 2-coating
Coat the slurry prepared in the first step evenly on the current collector (aluminum foil or copper foil, etc.) at the specified thickness, and dry the solvent;
The third step-pole piece punching
Punch the pole piece produced in the previous step into the specified size and shape;
Step 4-stacking
Assemble the positive and negative plates and the diaphragm together, and form the pole core after the glue is applied;
Step 5-Assemble the soft pack battery
