Abstract
There is provided an alkaline battery produced by sealing in an outer package body: a positive mixture containing at least one selected from manganese dioxide and a nickel oxide, a conducting agent, and an alkaline electrolytic solution (A) containing potassium hydroxide; a separator; and a negative mixture containing zinc alloy powder, a gelling agent, and an alkaline electrolytic solution (B) containing potassium hydroxide where a concentration of potassium hydroxide of the alkaline electrolytic solution (A) is 45 wt % or more, and a concentration of potassium hydroxide of the alkaline electrolytic solution (B) is 35 wt % or less. Because of this, an alkaline battery can be provided, which has desirable load characteristics, prevents the generation of gas, prevents a decrease in a storage property due to the reaction with an electrolytic solution, and has heat generation behavior suppressed at a time of occurrence of a short-circuit.
