The manufacturing process steps of lithium battery pole pieces can be subdivided into five processes: slurry preparation, slurry coating, pole piece rolling, pole piece cutting, and pole piece drying. It is understood that the battery assembly process is roughly divided into winding, casing, welding and other processes according to different battery specifications. The final liquid injection stage includes various processes such as liquid injection, exhaust, sealing, pre-filling, formation, and aging.(Cutting and s
