| description | A battery 2 includes an outer can 10 and an electrode group 22 that is housed in the outer can 10 together with an alkaline electrolytic solution, in which a positive electrode 24 included in the electrode group 22 includes a positive electrode substrate and a positive electrode mixture supported on the positive electrode substrate, the positive electrode mixture includes nickel hydroxide, yttrium oxide serving as a first additive, and niobium oxide or titanium oxide serving as a second additive, a total amount of the first additive and the second additive is 0.1 parts by mass or more and 2.5 parts by mass or less per 100 parts by mass of the nickel hydroxide, a mass ratio of the first additive and the second additive is in a relationship of 1:0.2 to 5, and the positive electrode mixture after an activation treatment has a resistivity of 1 Ω●m or more and 10 Ω●m or less. |
