PCT No. PCT/JP85/00066 Sec. 371 Date Aug. 12, 1985 Sec. 102(e) Date Aug. 12, 1985 PCT Filed Feb. 18, 1985 PCT Pub. No. WO85/03810 PCT Pub. Date Aug. 29, 1985.This invention uses a zinc alloy containing In, one element of Al or Mg and, optionally, one or both of Pb and Cd for the anode of a zinc-alkaline battery which employs zinc as an active material of the anode (2), aqueous alkaline solution as an electrolyte, and manganese dioxide, silver oxide, oxygen and so forth as an active material of the cathode (5). The use of such zinc alloy permits the reduction of the amount to be used of mercury employed for amalgation of the anode zinc surface with the object of corrosion inhibition, thereby enabling the provision of a low pollution zinc-alkaline battery.
