PURPOSE: To provide a pollution-free battery by making zinc beads contain indium thereon and specifying the amount of content of organic compounds. CONSTITUTION: A battery C is configured, being equipped with a zinc electrode containing, for example, 50ppm of C6 F13 C2 H4 (C2 H4 O)14 OH and 0.2% of Indium. Hereat although the battery C has a smaller content of a stabilizing chemical compound compared to battery A; the battery C has a rate of zinc corrosion of 1μl/gd, its discharge characteristics shows a remarkably improved discharging, and the drop in voltage after 1 hour is not observed. Having thus described the invention, the zinc electrode does not contain mercury, cadmium and lead, but contains indium of 0.005 to 1% by weight, extending on the surface of zinc beads, and also at least one organic stabilizing chemical compound of 1ppm to 1000ppm selected from the group consisting of poly-fluoride compounds of ethoxyfluoro alcohols and compounds of polyethoxy alcohol-alkyls. Thus in an alkaline battery having a zinc negative electrode, a clean battery can be obtained.
