  • Positive cobalt electrode for alkaline storage batteries and process for its production
    Patent number: 4202789
    Abstract: A positive cobalt electrode for alkaline storage batteries formed to contain aluminum hydroxide. A porous supporting grid of conducting material is immersed in an impregnating solution containing a cobalt salt dissolved in a solvent and at least one aluminum salt in solution. The grid is subsequently immersed in an alkaline medium where the hydroxides are precipitated.
    Type: Grant
    Filed: June 28, 1978
    Date of Patent: May 13, 1980

  • Negative cobalt electrode for an alkaline storage battery
    Patent number: 4119771
    Abstract: A negative cobalt electrode for an alkaline storage battery comprises a layered structure including a center layer of compact, sintered cobalt powder forming an electrically conductive supporting framework, and outer layers of porous, sintered cobalt powder. The outer layers form the electrochemically active surfaces of the electrode. A method is provided for making the electrode.
