An individual cell for a battery comprises an electrode stack disposed within a cell housing and a method for the production thereof. The individual electrodes, preferably electrode foils, are electrically connected to lead vanes, and at least electrodes of different polarity are separated and insulated from each other by a separator preferably a separator foil. Lead vanes of the same polarity are electrically connected to each other to form a pole. The lead vanes of a pole are electrically compressed with each other and/or welded to each other.
