PURPOSE:To obtain a negative cadmium plate for an alkaline storage battery, the utilization rate of the negative active material of which is enhanced, by immersing a pasted negative plate in a nickel salt solution, being followed by subjecting the plate to formation treatment. CONSTITUTION:A paste prepared by kneading cadmium oxide powder used as an active material with both a conductive agent and a binding agent solution, is applied to a core member before being dried. The thus obtained negative plate is immersed in a solution of a nickel salt such as nickel amidosulfonate, and dried. After that, the dried negative plate is subjected to formation in an aqueous alkaline solution to produce nickel hydroxide. Here, the amount of the nickel salt is adjusted so that the ratio by weight of cadmium oxide to nickel hydroxide after the formation is 100 to about 0.2-10. By the means mentioned above, nickel hydroxide can be homogeneously added to the entire plate, and the utilization rate of the negative active material is enhanced. |
