Winding is to coil the pole film made by the production process or the winding die cutting mechanism into PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal lithium ion battery cell, mainly used for square, round lithium battery production. The winding machine can be subdivided into square winding machine and cylindrical winding machine, which are respectively used for the production of square and cylindrical lithium batteries. Compared with cylindrical winding, the square winding process requires higher tension control, so the technical difficulty of the square winding machine is greater.
Lamination is the cell of lithium ion battery which is made of single pole sheet in die cutting process. It is mainly used in the production of soft pack battery. Compared with square and cylindrical cells, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal cells have obvious advantages in energy density, safety and discharge performance. However, the single stacking task of the laminating machine involves the parallel of multiple sub-processes and the collaboration of complex mechanisms, so complex dynamic control problems are needed to improve the laminating efficiency.
The speed of the winding machine is directly related to the winding efficiency, and the efficiency enhancement method is relatively simple. At present, the production efficiency and yield of laminated cell are different from that of wound cell. Liquid injection is a quantitative injection of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal electrolyte into the cell.
