PURPOSE:To increase the absorbing speed of the hydrogen gas generated in a battery and increase the battery capacity for the fixed volume of the battery by containing at least one kind of specific manganese additives in a nickel hydroxide electrode. CONSTITUTION:At least one kind of metal manganese, MnO, Mn2O3, MnO2, MnO3, Mn2O7, Mn (OH)3, MnCO3, K2MnO2, KMnO4 is contained as a manganese additive. Nickel hydroxide powder serving as an active material, metal manganese powder serving as an additive, and polytetrafluoroethylene powder are mixed at the weight ratio of 87:10:3, for example, it is filled in a foam nickel plate serving as an electrode substrate, and it is pressurized and molded to form a disk type nickel hydroxide electrode. This electrode has a very high hydrogen gas absorbing speed, when it is used for the positive electrode of an alkaline storage battery, the inner pressure of the battery is reduced, and the battery capacity can be improved. |
