Beyond its application in welding power lithium-ion batteries for electric vehicles, laser welding is widely used in the new energy sector. For instance, laser welding is employed in sealing the outer protective casings of new energy power battery cells, using laser conduction welding principles.
There are many parts that need to be connected in the battery system, and welding is often the most effective and reliable connection method. Laser welding has the advantages of non-contact, high energy density, accurate heat input control, and easy automation, which is considered to be the ideal choice for electric vehicle battery manufacturing.
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.
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.
