  • Active material of a nickel-cadmium generator negative electrode
    Patent number: 8889296
    Abstract: The hydration of cadmium oxide in the presence of nickel acetate gives the possibility of obtaining a compound of general formula Cd1-xNix(OH)2-y(CH3CO2)y with 0<x?0.05 and 0<y?0.10. This compound may be advantageously, used as an electrochemically active material of an anode of the envelope type of a nickel cadmium generator. This anode does not contain any sulfates responsible for the formation of short-circuits. Further, this anode has a high electrochemical yield. A method for preparing this compound and the anode is described.
    Type: Grant
