Abstract

The invention relates to a method for producing coated drawn metal. The inventive method is characterised in that the coating is applied to a closed metal foil which is transferred to a drawn metal after the coating process only. In particular, the coating can be embodied in such a way that it improves the adhesion of said drawn metal to electrode material and/or the surface electronic conductivity thereof. The inventive drawn metals are successfully used in the form of current derivators in/for an anode foil or in/or a cathode foil, for example for an electrochemical cell, in particular for a storage battery.

Claims (17)

1. Process for manufacturing expanded metal provided with a coating, characterized in that the coating is applied to a closed metal foil and the latter is converted into expanded metal only after the coating.

9. Expanded metal provided with a coating, obtained according to a process in accordance with one of the claims 1 through 7.
10. Expanded metal provided with a coating in accordance with claim 8 or 9, characterized in that the coating improves the adhesiveness of the expanded metal to an electrode material and/or the electron conductivity on the surface of the expanded metal.
11. Expanded metal provided with a coating in accordance with claim 10, characterized in that the coating was applied by means of a suspension containing graphite or another carbon material and a binder, or of an organic or inorganic-organic polymer, which was subsequently graphitized.
12. Use of expanded metal in accordance with claim 10 or 11 as a current collector in or for an anode foil or in or for a cathode foil.
13. Use in accordance with claim 12, characterized in that the current collector and the anode foil as well as the cathode foil are laminated together.
14. Use in accordance with one of the claims 12 or 13, characterized in that the anode foil and the cathode foil were prepared without the use of plasticizing agent.
15. Use of expanded metal in accordance with claim 10 or 11 in an electrochemical cell, especially a battery.
