(57) [Summary] To provide a high-energy density alkaline storage battery in a wide temperature range to enhance the charging efficiency of a nickel positive electrode during high-temperature charging. A paste of a paste-type nickel positive electrode for an alkaline storage battery containing nickel oxide as a main component contains two or more elements selected from yttrium, erbium, and ytterbium as a compound, or contains these compounds. One or more elements are contained as a compound, and one or more elements of the group consisting of lanthanum, praseodymium, neodymium, samarium, gadolinium, terbium, dysprosium, holmium, thulium and lutetium are further contained as compounds. |
