The invention relates to a single cell (1) for a battery, wherein the single cell (1) is formed from an electrode stack (6), the individual electrodes (6.1, 6.2) of different polarity, preferably electrode foils coated with an anode material or a cathode material Separator (6.3), preferably a Separatorfolie, are separated from each other insulating, wherein electrodes (6.1, 6.2) of the same polarity electrically conductively connected to a pole (P1, P2) and the poles (P1, P2) of the electrode stack (6) each electrically with an electrically conductive housing side wall (3, 4) are connected. In this case, the electrodes (6.1) of the anode are made of aluminum, the electrodes (6.2) of the cathode made of copper and the housing side walls (3, 4) of aluminum, wherein the housing side wall (4) facing the pole (P2) designed as a cathode has an inner side comprising intermediate layer (7) formed from copper or nickel. The invention further relates to a method for producing a single cell (1) for a battery. |
