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.
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.
The findings are applicable to all kinds of battery cell casings. Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.
The bonding interface eliminates metallurgical defects that commonly exist in most fusion welds such as porosity, hot-cracking, and bulk inter-metallic compounds. Therefore, it is often considered the best welding process for li-ion battery applications.
