困難である。Conventional technology and its problems Conventional cadmium negative electrode plates for alkaline storage batteries are carbonyl nickel powder kneaded with water and a sizing agent such as carboxycellulose or methylcellulose to form a slurry, which is then punched into a perforated steel plate plated with nickel on a steel plate. A so-called sintered substrate, which has been coated, dried and then sintered in a reducing atmosphere, is impregnated with a cadmium salt aqueous solution and neutralized to form cadmium hydroxide. However, this electrode plate has a drawback that the nickel powder is expensive, the amount of the active material filled by one impregnation is small, and the repetition of 5 to 6 times is required, and the process is complicated and the cost is high. In addition, it is difficult to increase the capacity because the space filled with the active material is small. On the other hand, a raw material powder of an active material such as metal cadmium is made into a paste using an organic solvent and applied to a perforated steel plate plated with nickel to a certain thickness, a nickel fiber sintered body or a nickel plated iron fiber. There is a so-called paste type electrode plate which is applied to the space of a sintered body or nickel foam. As the raw material of the active material for the paste type negative electrode plate, there are cadmium oxide, cadmium hydroxide, cadmium metal, etc. described above, but in general, cadmium oxide capable of high density packing is used as a main component. However, the paste of cadmium oxide and the polyhydric alcohol which is an organic solvent is very unstable in properties, cadmium oxide particles are easily solidified, and the viscosity is partially nonuniform. Further, the viscosity of the entire paste increases with time, the applied amount of the active material changes, and filling becomes difficult. Further, even if a small amount of water or salt is mixed, coagulation is promoted and the viscosity is lost in a short time. The paste whose viscosity has been lost does not return to the original state even if it is kneaded again, and it becomes impossible to fill the active material, so that its management is very difficult.

塩の存在で電価中性や塩析現象を呈する為である。Cadmium oxide-polyhydric alcohol-based pastes easily solidify and become highly viscous due to the presence of trace amounts of water and salts, because these pastes are a kind of coarse particles using cadmium oxide as a dispersoid and polyhydric alcohol as a dispersion medium. This is because it is a liquid colloid and exhibits a neutral charge value and salting out phenomenon in the presence of water or salt.

Is added and the mixture is stirred with a stirrer for 1 hour to obtain a paste-like active material. This paste is designated as A. For comparison, the paste prepared without adding sucrose is designated as B. The relationship between the storage time and the paste viscosity of both pastes is shown in FIG. As you can see from the figure, the conventional paste B is
In contrast to a viscosity of more than 10,000 cp, the paste A of the present invention shows almost no change in viscosity, and is about 1500 cp after 72 hours.
