摘要： PROBLEM TO BE SOLVED: To provide an electrolytic solution for alkaline battery that prevents production of hydrogen gas and generation of leakage of the battery and an alkalinebattery using this electrolytic solution.
SOLUTION: An aluminum ion is made contained in the electrolytic solution. As its method, aluminum powder or water-soluble aluminum compound or its solution is added in the electrolytic solution, and the ion concentration of aluminum in the electrolytic solution is made 5-200 ppm. Or the aluminum ion may be one eluted in the electrolytic solution from aluminum-contained zinc alloy powder that is the negative electrode active material.

摘要： PROBLEM TO BE SOLVED: To provide a zinc alloy powder for the negative electrode of an alka line manganese battery in which it is made possible to reduce the amount of hydrogen gas generation accumulated in the battery while maintaining or improv ing the discharging property, the negative electrode for the alkaline manganese battery and the alkali manganese battery using the same.
SOLUTION: The zinc alloy powder in which the surface of the zinc alloy powder containing one or more kinds of added metals of 0.001 to 0.1 wt.% selected from a group consisting of Al, Bi, Ca, In, Mg, Pb and Sn is coated with a liquid saturated hydrocarbon oil of 0.01 to 10 wt.% is used as the negative electrode 4 of the alkaline manganese battery 1. Because the surface is coated with the liquid saturated hydrocarbon oil at this negative electrode, generation of oxygen gas is suppressed, and the discharge property can be maintained or improved by controlling the coating amount.
