(57) Abstract: An alkaline storage battery exhibiting stable charge / discharge characteristics over a wide temperature range. SOLUTION: A nickel positive electrode 1 is formed by filling a nickel sintered substrate with a predetermined amount of nickel hydroxide by a chemical impregnation method, One or more compounds of elements selected from a, Sr, Sc, Y and lanthanoid elements are added. As the electrolyte of the alkaline electrolyte, cesium hydroxide, rubidium hydroxide, potassium hydroxide, and sodium hydroxide are used alone or in combination, and an alkali concentration of 1 is used. Set to 0 mol / L or more. |
