Common equipment in the processing of lithium battery packs

The important processing steps of the lithium battery pack are pulping. Special solvents and binders are used for pulping to mix with the powdered positive and negative active materials respectively, and after high-speed stirring, the positive and negative materials are made into slurry. Coating film Coating the prepared slurry uniformly on the surface of the metal foil, drying, and making the positive and negative pole pieces respectively. The assembly is placed in the order of the positive electrode-the diaphragm-the negative electrode-the diaphragm from top to bottom, and the battery pole core is formed by winding, and then through the process of injecting electrolyte and sealing to complete the battery assembly process , Make a finished battery. Chemical Testing Chemical Chemical uses dedicated battery charging and discharging equipment to perform charge and discharge tests on finished batteries. Each battery is tested, and qualified finished batteries are screened out before leaving the factory. Regarding the processing equipment used in these processing steps, the author of Cuneng Electric will focus on analyzing some important processing equipment below for everyone. The important processing equipment of lithium battery The coating machine is specially used to coat the positive and negative electrodes of the lithium battery, and it is coated on the aluminum foil and copper foil. The high-end coating machine has the advantages of extrusion die method and continuous coating, which can provide better coating effects. Winding machine Winding machine is mainly used for winding lithium battery cells, suitable for pole pieces and various diaphragms. A good winder can automatically wind up, automatically change needles, automatically paste and terminate tape and automatically unload, with simple operation and high efficiency. Heating shaping machine The heating shaping machine is also specially applied to the electric core. The heating plate is made of brass plate, which has good thermal conductivity, safety and environmental protection. Sealing machine Sealing welding machine is a plastic welding machine dedicated to welding lithium battery packs or large and irregular shaped thermoplastic workpieces.
