This post combines the application results of the above battery welding technologies in lithium-ion battery systems, and explores the influencing factors. Ultrasonic welding is a solid state battery welding process.
Is laser welding a good battery welding process?
Since laser welding has the smallest heat-affected zone in all battery welding processes and can be applied to the connection of multi-layer sheets, laser welding is considered to be the most effective battery welding process for lithium batteries. There are many factors affecting the battery welding process of laser welding.
How do you clean a battery cell for welding?
Follow these steps: Clean Battery Surfaces: Wipe the surfaces of the battery cells with a clean, dry cloth to remove any dirt, oil, or residue that could interfere with the welding process. Arrange Battery Cells: Arrange the battery cells in the desired configuration, ensuring they are aligned and spaced adequately for welding.
Why do battery cells need to be welded?
Battery cells are most often put into modules or packs when produced for electrically driven vehicles. The variable of greatest influence when welding battery packs is the contact resistance between the cell and the connection tab. It is crucial to minimize this variable as much as possible to prevent energy loss in the form of heat generation.
