PURPOSE:To reduce the amalgamation factor of negative-electrode zinc and make a primary cell to have low environmental pollution by adding Al or Mg; one or more of Pb, Cd, Sn; and Al, Ag, In, etc. to Zn to form amalgamated zinc alloy for use as a negative-electrode active material. CONSTITUTION:An alloy made by adding at least either Al or Mg, one or more of Pb, Cd, Sn, one or more of Ga, Tl, Ag, In to the main component Zn is pulverized, then it is amalgamated. This amalgamated zinc alloy is used as a negative electrode active material. Accordingly, the amalgamation factor is reduced and a zinc-alkaline primary cell having low environmental pollution and excellent in performance such as storage characteristic, leakage resistance can be obtained without deteriorating the corrosion resistance and discharge performance of the negative-electrode zinc. |
