  • Methods of producing electrodes for alkaline batteries
    Patent number: 4032697
    Abstract: A process is described for making alkaline batteries in which particular attention is given to the pretreatment of nickel plaques prior to impregnation. This pretreatment involves production of a uniform thin oxide film on the nickel plaque surface under carefully controlled conditions. This pretreatment prevents corrosion under conditions for commercial production of electrodes for alkaline batteries and permits not only higher loadings but more uniform loadings of the electrodes.
