IMPROVED CATHODE FOR ZINC AIR CELLS

摘要

The invention relates to an improved hydrophobic cathode for use in a zinc-air cell, and to a method for making said cathode. The cathode comprises an admixture of discrete particles of gamma manganese dioxide and carbon and a polymeric halogenated hydrocarbon. The method includes the step of intensively milling the manganese dioxide to reduce the particle size thereof and homogeneously admixing the manganese dioxide with the carbon particles.
