(57) [Problem] To provide an alkaline storage battery having a high energy density by increasing the capacity of the positive electrode and the negative electrode in an alkaline storage battery using a positive electrode mainly composed of nickel oxide. SOLUTION: In order to improve the capacity density of the positive electrode, the active material is coated on the surface and / or the vicinity of the surface with a highly conductive cobalt oxyhydroxide having a high specific conductivity of 15 Ω · cm or less. At least one element selected from manganese, chromium, aluminum, and calcium is dissolved in a range of 3 mol% to 15 mol%. |
