  • Patent number: 4692229
    Abstract: An electrode chamber unit intended for use in an electrochemical cell including at least one porous percolating electrode in the form of a bed of electrically conductive particles, e.g. of graphite.
    Type: Grant
    Filed: June 15, 1984
    Date of Patent: September 8, 1987
    Assignee: ElectroCell AB
    Inventors: Ake Bjareklint, Daniel Simonsson
  • Patent number: 4382113
    Abstract: A method of joining together a plurality of graphite members providing a low transition resistance is described. The method includes the steps of interposing a layer of a thermally sensitive material between the graphite members to be joined, applying pressure to force the graphite members together, applying sufficient heat to melt the thermally sensitive material, and releasing the pressure after providing a period of time for cooling. The thermally sensitive material is preferably composed from a thermoplastic material, and the heat for melting this material is preferably provided by resistance brazing.
    Type: Grant

  • Patent number: 4343982
    Abstract: A method of joining two metal members to a graphite member to form a structure having a low transition resistance is described. The method includes the steps of providing a plurality of openings in the graphite member, interposing the graphite member between the two metal members and positioning the metal members to cover the openings in the graphite member, and resistance spot welding the metal members to the graphite member at the openings in the graphite member. This method is advantageous in forming a bus-bar connection between a pair of opposite polarity graphite electrodes in an electrochemical cell stack, such as a zinc-chloride battery. In this particular application, it is preferred that titanium be used for the metal members.
