The purpose of this project is to conduct a comparative literature study of different welding techniques for welding batteries. The compared techniques are resistance spot welding, laser beam welding and ultrasonic welding. The performance was evaluated in terms of numerous factors such as production cost, degree of automation and weld quality.
The search was then performed using Uppsala University’s Library database and Google scholar which cover a wide range of articles and sources. Three methods for welding batteries were given in the template, being laser beam-, ultrasonic-, and resistance spot welding.
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.
Proper preparation of lithium batteries is crucial for successful spot 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.
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.
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.
