PURPOSE:To heighten energy density, to increase workability, and to reduce cost by containing silicate in a negative electrode of alkaline storage battery mainly comprising cadmium oxide powder. CONSTITUTION:When an active material mainly comprising cadmium oxide is kneaded with water, silicate is added to a mixture. By adding the silicate, conversion of cadmium oxide in paste into cadmium hydroxide caused by water can be prevented, and expansion of the paste is also prevented. By applying the paste obtained to an electrode substrate, a cadmium electrode having high energy density similar to that obtained by using the paste prepared with organic solvent can be obtained. |
