　　Strictly speaking, this type of franchise fraud is common, and it is not recommended to participate because lithium-ion battery equipment generally does not have franchises. If you want to join, be sure to investigate clearly. Lithium-ion battery packaging technology absolutely requires professional training and learning. At present, many manufacturers that sell equipment can learn technology. As long as they purchase relevant equipment, testing instruments and tools, and provide relevant testing procedures for lithium-ion battery operations, they can assemble and produce lithium-ion batteries by themselves without charging a franchise fee. However, quality issues and safety issues are two sharp swords.

　　It is very unrealistic to buy production equipment and process lithium-ion batteries at home. As we all know, the processing technology of lithium-ion batteries is very strict. If it is not handled properly during the production and storage process, explosions, combustion and other emergencies can easily occur. What's more, whether the private processing equipment is complete and the relevant experience is insufficient are also problems. The lithium-ion battery processing equipment for sale circulated on the Internet is subsequent assembly and welding detection equipment, not raw material processing equipment. It is unknown whether it is true.

　　Lithium-ion battery processing technology (1) Special solvents and binders are used for slurry mixing with powdered positive and negative active materials respectively, and after high-speed stirring and averaging, slurry-like positive and negative materials are made. (2) Coating film: Apply the prepared slurry evenly on the surface of the metal foil, dry it, and make positive and negative electrode plates respectively.

　　(3) Assemble in the order of positive electrode sheet - separator - negative electrode sheet - separator from top to bottom, and then roll it into the battery pole core, and then go through processes such as injecting electrolyte and sealing to complete the battery. The assembly process creates the finished battery.

　　(4) Chemical formation uses special battery charging and discharging equipment to detect charge and discharge of finished batteries, conducts tests on each battery, and selects qualified finished batteries before leaving the factory.
