Can laser welding be used in the production of lithium battery modules?
To investigate the application of laser welding in the production of lithium battery modules for electric vehicles, this study employs the finite element method to simulate the welding process of lugs and busbars in lithium batteries under different parameters.
What is lithium ion battery laser welding?
High Welding Quality: Lithium-ion battery laser welding equipment uses a non-contact welding method, which means there is no mechanical contact, thus avoiding the possibility of material damage after welding.
How does laser welding affect the temperature of lithium battery lugs?
1. The heat during the laser welding of lithium battery lugs is distributed centrally within the weld region, resulting in a significant temperature gradient in front of the molten pool and a smaller gradient at the rear. During the cooling process after welding, the temperature decreases rapidly within 5 s.
Why do weld power batteries with laser welding technology?
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.
How does laser welding work?
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.
Why is ultrasonic welding used in lithium battery production?
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.
