Abstract: A battery includes a stack of bipolar individual battery cells, each of which includes an electrode stack and two sheet metal covers bounding the individual battery cell at least in the stacking direction. The electrode stack is connected to at least one of the sheet metal covers by at least one weld. In the region of the at least one weld, the sheet metal cover welded to the electrode stack and/or the sheet metal cover of the adjacent individual battery cell in contact with the sheet metal cover is/are of a set-back design. As a result, the sheet metal covers of adjacent individual battery cells do not have any contact in the region of the at least one weld.
