Abstract
A non-sintered nickel electrode for use in alkaline storage cells includes an active material comprising a solid solution of nickel hydroxide mixed with manganese, the solid solution further incorporating one or more elements selected from a group consisting of cobalt, cadmium, calcium and magnesium; an active material comprising a solid solution of nickel hydroxide mixed with manganese and zinc, the solid solution further incorporating one or more elements selected from a group consisting of cobalt, cadmium, calcium and magnesium; or an active material comprising nickel hydroxide with manganese added thereto, some of which manganese is incorporated in a solid solution of nickel hydroxide and the rest of which manganese exists as liberated from the solid solution of nickel hydroxide.
