Application scheme of laser welding for lithium batteries

The production process of lithium-ion batteries or battery packs is extremely complex and diverse, with numerous procedures such as explosion-proof valve sealing welding, pole ear welding, soft connection welding, safety helmet spot welding, battery shell sealing welding, module and PACK welding, etc. Laser welding is considered an ideal process. The materials used for welding power batteries are mainly pure copper, aluminum, aluminum alloys, stainless steel, etc.
