Abstract
A rechargeable alkaline storage cell and a method of manufacturing the cell. The manufacturing method mainly comprises a first step of forming a cadmium electrode by coating a conductive support with a kneaded active material in paste form including cadmium oxide as a main component thereof while suppressing hydration of the kneaded active material, and a second step of producing cadmium hydroxide through hydration of the cadmium oxide. The cell comprises, as main components thereof, a positive electrode including a rechargeable active material, a paste type negative cadmium electrode including cadmium hydroxide produced by chemical hydration, a separator disposed between the positive electrode and the negative electrode, and an electrolyte impregnating the separator.
