Whether to power our latest portable electronic device, power tool, or hybrid/electric vehicle, the removable battery pack is essential to our everyday lives. Tab-to-terminal connection is one of the key battery pack welding applications.
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.
Other joining methods such as micro-tungsten-inert-gas welding (micro-TIG), micro-clinching, soldering, and magnetic-pulse welding exist and have been proposed for battery assembly applications, but they are not well established, and therefore their feasibility is still being evaluated, or they are not widely used in the industry.
A parametric study of the welding of cylindrical Hilumin battery cells to thin sheet connectors was also carried out . The authors investigated the effects of various process parameters such as tip geometry, connector strip material and shape, maximum supply voltage, welding time and force, and the distance between two electrodes.
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 means that, on the one hand, there may be accessibility issues as the testing is performed on already assembled modules or packs, and on the other hand, key performance indicators for battery welding applications, such as electrical and fatigue performance of the joints, are not served.
