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.

Battery, comprising at least a battery cell, which is arranged within a battery housing, characterized in that the battery housingis partially filled with a cooling liquid. Method for cooling of said battery, wherein at least a portion of the cooling liquidis evaporated.

Battery having a housing partially filled with cooling fluid

An accumulator comprises at least one galvanic cell and a receiving device for supporting the galvanic cell(s) of the accumulator. The receiving device comprises at least one protecting wall for receiving energy by means of elastic and/or plastic deformation. The protecting wall encases the at least one galvanic cell at least partially and has a thickness which is at least partially less than about 1/10 of the characteristic edge length of the at least one galvanic cell.
