Thanks to its efficiency and precision, laser welding equipment has become an essential tool for lithium battery manufacturers. During the assembly and welding of lithium battery pack, a significant amount of nickel-plated copper or nickel-plated aluminum is used to connect battery cells. The primary method of connection is nickel-aluminum welding.
In lithium battery production, ultrasonic welding is commonly used to connect battery cells to electrode foils, electrode cells to electrolyte films, and battery cells to battery casings and other components. It provides a highly accurate and stable weld, avoiding thermal damage and the introduction of impurities.
Since power batteries need to have multiple welding parts and it is difficult to carry out high-precision requirements met by traditional welding methods, laser welding technology can weld welds with high quality and automation due to the characteristics of small welding consumables loss, small deformation, strong stability and easy operation.
Environmentally Friendly: Laser welding of lithium-ion batteries does not produce any harmful substances, making it very environmentally friendly. Additionally, as it does not require the use of solvents or other chemicals, it can also reduce waste production. 4.
Laser welding uses a laser beam to heat the weld joints to a high temperature, causing the materials to melt and join together. Laser welding offers high energy density and joint precision. Laser welding is commonly used to join components such as electrode foils, battery casings, and battery connecting tabs.
TIG welding is commonly used to join components such as battery cases, battery covers, and battery leads. Laser welding lithium ion batteries is a highly advanced and efficient welding method. It not only improves production efficiency but also ensures product quality and stability. 1.
