1507446 Molten electrolyte batteries ROCKWELL INTERNATIONAL CORP 4 Jan 1977 [15 March 1976] 0051/77 Heading H1B A secondary battery having molten electrolyte has the electrode active material contained in cells 12 of, e.g., Fe, steel, Ni or Ni-steel, carbon, Mo, Ti, the ends of which are closed by one or more electrolyte permeable members 18, 20, e.g. a wire screen or sintered plaque of Ni or Fe. The active negative material 16 may be an alloy of Li, Na, K or Rb with, e.g., Al, In, Sn, Pb, Ag, Ca or Si and the positive a transition metal chalcogenide, e.g. sulphides of Cu, Fe or Ni or oxide of Ni. The electrolyte may be halides of alkali metals, and examples of binary and ternary eutectic mixtures are given. It may also contain a chalcogenide. In modifications (Figs. 2a and 3a, not shown) the cells may be of square or circular section. In a cell, Fig. 4, the electrodes are supported from conductive rods 124, with ceramic separators 132, e.g. SiN, and springs 136 of partly compressed graphite or carbon fibres. |
