A method produces electrode windings, in which method a strip- or ribbon-like anode and a strip- or ribbon-like cathode are provided and flat collector lugs are formed on at least one longitudinal side of the anode and of the cathode at varying distances and/or contours are cut into the longitudinal sides of the electrodes. The anode and the cathode are wound up together with a strip- or ribbon-like separator to form a winding with the sequence anode/separator/cathode. The method is distinguished, in particular, in that the process of forming collector lugs and/or of cutting contours and the process of winding up overlap with respect to time.
