Abstract

PURPOSE:To improve active substance application rate and amount of impregnation of active substance by holding th cadmium hydroxide obtained by chemical impregnation in the sintered body as metal cadmium by the negative electrolysis. CONSTITUTION:An active substance is changed to cadmium hydroxide by chemical impregnation and thereafter the cadmium hydroxide is changed to a metal cadmium by the negative electrolysis and the active substance is held within a substrate. Since the cadmium hydroxide is changed to metal cadmium by negative electrolysis, it is held in the substrate as the active substance metal cadmium similar to that obtained by the electrolysis impregnation. Accordingly, both active substance application rate and amount of impregnation of active substance can be improved up to a high level.

量が多いという利点がある。The chemical impregnation method has the disadvantage that the active material utilization rate is high, but the amount of impregnation is small due to the principle itself and problems such as surface clogging.On the other hand, the electrolytic impregnation method has a low utilization rate, but the amount of impregnation is small. The advantage is that there are many.

共向上させることにある。The object of the present invention is to first precipitate cadmium hydroxide in the pores of a sintered body by a chemical impregnation method, and then electrolyze this cadmium electrolytically to hold it in the sintered body as metallic cadmium. , active material utilization rate, live material wage! The aim is to improve both quantity and quantity.

最高値を示す。The relationship between impregnation method and utilization rate is shown in the drawing. It can be seen that it is 110% better. The same applies to the case of 1C discharge, which is about 10% superior to chemical electrolytic impregnation and electrolytic impregnation. Further, since the 2tfl-containing cadmium hydroxide is converted into metal cadmium by negative electrolysis, it is retained in the substrate as the active material metal cadmium in an amount equivalent to that of electrolytic impregnation. In this way, both the water matrix and the water matrix are at a high level, and the discharge capacity shows the highest value when the number of impregnation cycles is the same.
