わるく、充電電圧が上昇するためと考えられる。Conventionally, the manufacturing method for cathode plates for nickel-cadmium storage batteries is to sinter nickel powder and fill its pores with cadmium, an active material (sintering method), or to apply cadmium metal onto punched metal using negative electrolysis. a method of precipitating
Another method is to apply paste or slurry cadmium oxide to the punched metal. The method of applying this paste is characterized in that it is simpler in terms of process than the other methods, allows for mass production, and allows easy control of the amount of active material. However, it has the drawback that the charging voltage tends to be high (therefore, hydrogen gas is generated and the battery life is short. This is because the battery is assembled in the state of cadmium oxide, so the conductivity of the cathode plate This is thought to be due to the charging voltage increasing.

二。An embodiment of the present invention will be described. When 100% of cadmium oxide is mixed with 5% by weight of an organic binder (polytetrafluoroethylene) and % by weight of nickel powder (Sii), the voltage at the end of charging is approximately 1.5V. Indicates equivalent value. Note that FIG. 1 shows the relationship between the amount of nickel added to the metal powder and the voltage at the end of charging. Thus, it can be seen that when the amount of nickel added is about 3% or more, it has a significant effect on the voltage at the end of charging. FIG. 2 shows the relationship between metallic nickel powder and discharge capacity after 30 discharges. The discharge is 0.2
There is no capacity deterioration due to the addition of nickel powder in G to IC discharges, or 2 in 3C discharges as shown in Figure 2.
