[0002] Solid-state batteries use solid electrolytes instead of liquid electrolytes, and the interfacial bonding strength directly affects the battery's cycle life and safety. Laser welding uses high-energy density, non-contact processing to achieve precise welding of solid electrolytes and electrodes in a vacuum or inert gas environment, avoiding material contamination or thermal damage caused by traditional welding. Solid-state battery modules need to connect dissimilar metals such as aluminum, copper, and nickel. Traditional welding is prone to cracks or cold welds due to differences in melting points. Laser welding uses the deep-penetration effect to form small holes on the material surface, allowing light energy to directly penetrate the bottom of the holes, achieving spatter-free fusion of dissimilar metals. However, existing solid-state battery module laser welding equipment cannot quickly adjust the pressing position during welding, reducing its applicability to welding different batteries.
