A cell mainly includes the anodes and cathodes, a module includes multiple cells, and a pack includes multiple modules. The three most common metal-to-metal joints in a lithium-ion battery pack are foil-to-tab, tab-to-tab, and tab-to-bus.
The image below shows a schematic of a large format lithium-ion pouch style cell. The foil-to-tab weld is needed to gather all the anode and cathode foils inside the cell and join them to tabs which exit the cell casing allowing the cell’s energy to be transferred to an external source.
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.
UWB is also suitable for creating electrical connections between cylindrical battery cells. Although proper fixation of the cell is paramount for the welding, as any significant lateral movement will reduce the vibration amplitude and consequently diminish the power of the welding process.
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.
