  • An improved secondary battery or cell comprises an anodic reaction zone containing a molten alkali metal reactant-anode in electrical contact with an external circuit, one or more cathodic reaction zones containing a cathodic reactant, a cation-permeable barrier to mass liquid transfer interposed between and in contact with the anodic and cathodic reaction zones, and a current collector that is at least partially exposed to the cathodic reactant and is in electrical contact with both the cation-permeable barrier and the external circuit. The cathodic reactant, when the battery or cell is at least partially discharged, is selected from the group consistingmore » of a single-phase composition comprising molten polysulfide salts of the anodic reactant and a two-phase composition comprising molten sulfur and molten sulfur-saturated polysulfide salts of the anodic reactant. The improvement comprises employing in the device a current collector comprising a graphite body bearing a coating of pyrolytic graphite on at least those surfaces that are exposed to the cathodic reactant.« less

The improvement is the use of a current collector comprising a graphite body bearing a coating of vitreous carbon on at least those surfaces which are exposed to the cathodic reactant. 3 figures.« less
  • A nickel-aluminum reserve battery is described which consists of: (1) a case within which are disposed at least one bipolar plate comprising: (i) an electrode comprising battery material, the battery material consisting essentially of nickel hydroxide, the material containing --OH groups, and (ii) and electrode comprising aluminum, (2) a storage reservoir containing aqueous alkali hydroxide electrolyte near the case, and (3) means to transfer stored electrolyte to the electrodes where the nickel hydroxide containing electrode is connected to a current collector, which current collector is in turn connected to the aluminum electrode of the bipolar plate by means of anmore » electrically conducting bonding medium.« less
