Abstract: A stamped film to be connected to an additional film has a stamped pattern defining at least one dividing line that is interrupted in a regular pattern by webs, wherein the webs each have a width that is, on average, less than an average spacing between two adjacently positioned ones of the webs, respectively. The stamped pattern has, at least in one direction, several dividing lines extending parallel to one another or has several dividing lines extending perpendicularly to one another. When mirroring the stamped film at a mirror plane that intersects the stamped film centrally and perpendicularly to the dividing lines, the webs of the dividing lines will not be superimposed on webs of a stamped film that has not been mirrored when superimposing the mirrored stamped film on the stamped film that has not been mirrored. The stacked films form electrochemical or electrochromic compounds.

Abstract: The present invention pertains to a process for manufacturing expanded metal provided with a coating, characterized in that the coating is applied to a closed metal foil and this is converted into expanded metal only after the coating. In particular, the coating may be a coating that improves the adhesiveness of the expanded metal to an electrode material and/or the electron conductivity on the surface of the expanded metal. Such expanded metals can be advantageously used as current collectors in or for an anode foil or in or for a cathode foil, e.g., in an electrochemical cell, especially in a battery.
