To retard the generation of hydrogen gas and enhance charging characteristics at low temperature by containing cadmium, β type cadmium hydroxide, γ type cadmium hydroxide in an electrode, separating the β type cadmium hydroxide from the γ type cadmium hydroxide so as not to come in contact with each other, and holding them with one kind of polymer binder selected from two and three kinds.

A paste type cadmium electrode is manufactured with paste prepared by dispersing β type cadmium hydroxide, metallic cadmium, and nylon fibers in an aqueous solution of one of PVP, PTFE in the specified solid composition ratio. Another paste is prepared by dispersing γ type cadmium hydroxide, metallic cadmium, and nylon fibers in an aqueous solution of one of CMC, MC, and PVA in the specified solid composition ratio, and applied to the cadmium electrode. The viscosity of the later paste is made lower than the that of the former paste. The drying temperature of both paste after coating is preferable to set to 150-200°C.
