ABSTRACT:
An alkaline storage battery includes, as main constituent elements, a positive electrode having nickel hydroxide as an active material, a negative electrode, a separator, and an electrolyte made of an aqueous alkali solution, and a foamed three-dimensional porous substrate composed of nickel as a main component is used as a core substrate of the positive electrode, and the weight ratio of this core substrate in the positive electrode is set to 30% to 50%, thereby allowing both electron conductivity and ion conductivity of the positive electrode, with long life and high output even under severe conditions.
