“…What is necessary for welding here is the absence of gaps between the joining partners, but no further pressure. [ 5 ] The electrical resistance of the resulting joined connection must be particularly low to ensure the functionality of the individual battery cell over a long period of time. In addition, the formation of weld spatter should be avoided, as this can lead to a short circuit in the cell.…”
