Abstract
A manganese dry battery includes an anode zinc can made of a zinc alloy containing 0.001-0.5 wt. % of titanium and at least one element selected from the group consisting of 0.001-0.05 wt. % of indium and 0.001-0.05 wt. % of bismuth, or a zinc alloy further containing 0.01-0.4 wt. % of lead. Even without heavy metals such as Hg and Cd, the zinc alloy anode can has a corrosion-resistant property and mechanical strength equivalent to or greater than those of the conventional zinc anode can, thereby giving a low pollution zinc-carbon battery having a storage characteristic equivalent or superior to that of the conventional zinc anode can.
