PURPOSE:To produce a zinc alkaline battery of low public pollution by improving corrosion-proofness and reducing mercurating ratio by making zinc alloy containing lead, cadmium, thallium, silver in specific amount into a negative pole active matter. CONSTITUTION:Zinc alloy containing lead of 0.01-0.5wt%, cadmium of 0.01-0.5wt% and one or two kinds of thallium and silver of 0.01-0.5wt% in total is made to be a negative pole active matter to produce a zinc negative pole 2. And it is combined with a positive pole 5 containing manganese dioxide and silver oxide mainly and electrolyte containing caustic potash mainly to form a zinc alkaline battery. Then, diffusion of mercury in particle field and into particle of zinc alloy is restrained by adding Tlm Ag as well as Pb, Cd to the zinc alloy and corrosion-proofness can be improved by adding a little amount of mercury, and mercurating ratio of negative pole zinc can be reduced and a battery of low public pollution can be obtained. |
