What is the processing and production process of lithium battery soft pack cells?

The processing and production process of lithium battery soft-pack batteries: soft-pack lithium batteries are thermally packaged, while metal shell batteries are generally welded (laser welding). The reason why soft-pack batteries can be thermally packaged is that they use aluminum-plastic packaging film. The first step-the preparation of electrode slurry is important to mix the electrode active materials, binders, solvents, etc., and stir and disperse sufficiently to form a slurry; the second step-coating the slurry prepared in the first step Evenly coat the current collector (aluminum foil or copper foil, etc.) with the specified thickness, and dry the solvent; the third step-pole piece punching, punching the pole piece produced in the previous step into the specified size and shape; fourth Step-stack the positive and negative plates and the separator together, after the glue is completed, form the pole core; the fifth step-assemble the soft pack battery statement: Some pictures and content of the articles published on this site are from the Internet, such as If there is any infringement, please contact to delete the previous article: What behavior will damage the battery?
