ABSTRACT:
A metal current collecting substrate for an air cathode in an electrochemical metal air cell is provided for, wherein the substrate is hardened by one of the steps of sandblasting, shotblasting, plastic deformation of the substrate below the recrystallization temperature range of the metal thereof, and heating the substrate to above the transformation temperature of the metal thereof followed by quenching the substrate below the transformation temperature of the metal thereof. Catalytically active materials, most preferably a mixture of carbon and manganese dioxide, are pressed or otherwise disposed upon the hardened substrate. The substrate is capable of being connected to electrical circuitry. Most preferably, the substrate is a metal screen that has been hardened, roughened and pitted by sandblasting before the catalytically active materials are disposed thereupon, and before the substrate is incorporated into an electrochemical metal air cell.
