ABSTRACT:
A prismatic sealed alkaline storage battery with a nickel hydroxide electrode comprising a nickel substrate having a porosity of from 86 to 98% and containing as an active material from 10 to 20% by weight of cobalt based on the sum of nickel and cobalt; the alkaline storage battery using the same as a positive electrode and a mixed solution as an electrolyte comprising sodium hydroxide and potassium hydroxide. The battery has a high Ah efficiency in a wide temperature range, a higher energy density and a longer operating life in a low termperature of 0.degree. C. or less and a high temperature of 50.degree. C. or more, thereby providing a prismatic sealed alkaline storage battery for the power sources including cycle service use, such as electric vehicles.
