Abstract

The invention relates to a battery (0), comprising a plurality of self-contained, substantially cuboid cell housings (1), in each of which a side face is formed at least in some regions as a negative pole (−) and the opposite side face is designed at least in some regions as a positive pole (+), wherein the cell housings (1) bear against one another, with the pole (−) on the pole (+), and extend between a positive contact (14) and a negative contact (13), and wherein the cell housings (1) are each enclosed by an electrically non-conductive, mechanically supporting frame (2). The aim of the invention is to provide such a battery which has lower internal resistance and is therefore suitable for applications which require rapid charging or discharging (high-power applications). Said aim is achieved by at least one flat bimetal element (7) which is formed of copper and aluminium and is coated with active anode material (9) on the copper side and with active cathode material (8) on the aluminium side and which extends within one of the cell housings (1) parallel to the poles (+), (−) thereof, and is attached to the frame (2) of the cell housing (1) so as to provide ionic sealing and the cell housing (1) is thus divided into at least two series-connected galvanic cells.
