How do polymer battery manufacturers produce lithium batteries

The first step – electrode slurry preparation

 

Mainly, the electrode active material, the binder, the solvent, and the like are mixed together, and after fully mixing and dispersing, the slurry is formed.

 

The second step – coating

 

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

 

The third step – the pole piece die cutting

Punching the pole piece manufactured in the previous step into a specified scale shape

The fourth step – lamination

 

The positive and negative electrodes and the barrier are assembled together, and after the glue is finished, the core is formed.

 

Step 5 – Assembling the soft pack battery

 

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

 

The sixth step – injection

 

Write the specified amount of electrolyte into the inside of the soft pack battery (of course, the battery core should be baked, and the liquid injection operation should be carried out in a low humidity environment. It is not good if the moisture content is too much)

 

Step 7 – Battery Seal

 

Extracting the gas inside the cell in a vacuum environment and sealing it

 

Of course, there are processes such as formation, aging, classification, and shaping.
