Alkaline battery and method for manufacturing alkaline battery

A method for manufacturing an alkaline battery, the alkaline battery comprising a container and a positive electrode, a negative electrode, a separator, and an electrolytic solution that are accommodated in the container, the method comprising:

• preparing the negative electrode consisting of a gel-like negative electrode mixture containing a mixed aqueous solution in which a potassium hydroxide aqueous solution having a concentration of 45% and a sodium hydroxide aqueous solution having a concentration of 27% are mixed at a mass ratio of 88:12 to 95:5, and a negative electrode active material;
• preparing the positive electrode consisting of a positive electrode mixture comprising a positive electrode active material containing silver oxide and manganese dioxide, in which a blending ratio of manganese dioxide in the positive electrode mixture is set to 50% by mass or less;
• preparing the electrolytic solution consisting of a potassium hydroxide aqueous solution having a concentration of 40% to 50%;
• and
• accommodating the positive electrode, the negative electrode, the separator, and the electrolytic solution in the container.
