  • Secondary zinc electrode for a secondary electro-chemical cell
    Patent number: 4492744
    Abstract: A secondary zinc electrode, for example, for a nickel/zinc cell has an electrically conductive support onto each major surface of which is pressed an active zinc material. A grid structure defining a plurality of compartments is pressed into the material on each major surface of the support so as to separate the active material into a plurality of physically separate areas. Such an arrangement mitigates the shape change problem to which secondary zinc electrodes are prone in service.

  • Current collector for electrochemical cells and method of making
    Patent number: 4212933
    Abstract: A cathode current collector for a sodium sulphur cell is formed of a metal substrate, for example of a nickel alloy such as Inconel 600, which is provided with a firmly adherent coating of carbon which is produced by decomposition of a carbon-containing gas in a glow discharge with the substrate heated to a temperature of 200.degree. C. to 1000.degree. C. in an electric field, conveniently a radio frequency field employed for inductively heating the substrate.
