▎ 摘　　要

NOVELTY - A silver-copper oxide-nitrogen-doped reduced graphene oxide based air electrode comprises foamed nickel supporting catalyst layer, foamed nickel current collector and waterproof-moisture permeable layer adhered to both sides of the catalyst layer and current collector, where the foamed nickel supporting catalyst layer has structure, in which catalyst layer is grown on the foamed nickel current collector, the catalyst is oxygen reduction catalyst, half-wave potential of the foamed nickel supporting catalyst layer is -0.15 to -0.24 V with respect to mercury/mercury oxide electrode and the electrode has pseudocapacitance of 200-674 F/g. USE - Silver-copper oxide-nitrogen doped reduced graphene oxide based air electrode for zinc-air battery. ADVANTAGE - The air electrode has excellent supercapacitor performance, and improves charge and discharge efficiency of zinc-air battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing the silver-copper oxide-nitrogen-doped reduced graphene oxide based air electrode.
