ZINC ALKALINE BATTERY

摘要

PURPOSE:To provide a zinc alkaline battery in which deterioration of errosion resistance and discharge performance as a battery is eliminated by using non- amalgamated zinc alloy powder as a cathode active material. CONSTITUTION:As a cathode active material, non-amalgamated zinc alloy powder is used in which a given quantity of induim is added on the surface of zinc alloy powder containing a given quantity of aluminum and/or a given quantity of calcium besides unavoidable impurities, and having bulk specific gravity of 2.90-3.50(g/cm<2>).
