Analyze the production process of polymer lithium-ion batteries

The production process of polymer lithium ion batteries is analyzed. The production of polymer lithium ion batteries: important raw materials for lithium polymer batteries are lithium oxide, graphite, solid polymer electrolyte, metal collection liquid, conductive agent, adhesive, and aluminum plastic film. Wait. Figure 7-126 is the production process of polymer lithium ion batteries. Usually, the active material of the electrode is mixed with the solvent, the conductive agent, the binder, and the mechanism of the membrane electrode membrane. Then the electrode, the solid polymer electrolyte membrane, and the membrane metal hydrothermal solution are formed. Integrated, blanking, battery assembly, aluminum-plastic sealing, test procedures, such as fast battery products. Introduction to the production of polymer lithium ion batteries Since the important difference between polymer lithium ion batteries and liquid electrolytes lies in the membrane and electrolyte, the preparation process of the electrode material is basically the same as that of the liquid electrolyte. The important difference lies in the assembly process of the electrolyte membrane and the battery. The manufacturing process of polymer lithium ion battery mainly includes the manufacturing process of polymer positive electrode film, negative electrode film, polymer film and so on. Belcore is the first company to produce lithium polymer batteries. The first is the combination of liquid-collecting aluminum mesh, copper mesh and electrode material (film) to form a positive electrode and a negative electrode. Through hot pressing, the plasticized polymer PVDFHFP is melted and sandwiched between the electrodes to form a battery pack. The battery pack is placed in an organic solvent, the plasticizer (such as dibutyl phthalate) is extracted, and the battery pack is placed in an aluminum-plastic film box, decompressed or dried, and then injected with electrolyte to form a gel. This manufacturing method can make the internal interface of the battery have good contact, the battery has low internal resistance, high capacity, and long cycle life. Among the most important processes are the pretreatment of electrode materials and the stirring of electrode paste, the preparation of electrode films and the cutting of electrodes, the assembly of individual cells and the formation of cells. Environmental dehumidification and packaging materials are also important quality assurance conditions. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
