Moreover, the high-volume production requirements, meaning the high number of joints per module/BP, increase the absolute number of defects. The first part of this study focuses on associating the challenges of welding application in battery assembly with the key performance indicators of the joints.
This welding process is used primarily for welding two or more metal sheets, in case of battery it is generally a nickel strip and positive terminal/negative terminal of the battery together by applying pressure and heat from an electric current to the weld area. Advantages: Low initial costs.
Different welding processes are used depending on the design and requirements of each battery pack or module. Joints are also made to join the internal anode and cathode foils of battery cells, with ultrasonic welding (UW) being the preferred method for pouch cells.
