What is the basic assembly process of lithium-ion batteries?

Lithium-ion battery assembly process Lithium-ion battery technology is very strict and huge, here can only briefly introduce a few important processes. (1) A special solvent and binder are used for pulping to separate and mix with the powdery positive and negative active materials, and after high-speed stirring and evenly weighing, the positive and negative materials are made into slurry. (2) Coating: The slurry is evenly coated on the surface of the metal foil, dried, and separated to form positive and negative pole pieces. (3) The assembly is placed in the order of the positive electrode-the barrier-the negative electrode-the barrier 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 Assembling process to make product battery. (4) Chemicals uses special battery charging and discharging equipment to conduct charging and discharging tests on product batteries. Each battery is tested, and qualified product batteries are screened out before leaving the factory. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
