1,182,238. Alkali-metal-sulphur secondary cells. FORD MOTOR CO. Ltd. 3 April, 1968 [3 April, 1967], No. 15976/68. Heading H1B. Alkali metal-sulphur cells in which the anode and cathode form opposite walls of a container 11 and the compartment therebetween is divided by a cationically conductive solid electrolyte 13 into anodic and cathode reaction zones 15, 17, contain reactant feeders comprising a porous object in each reaction zone, that in the anodic reaction zone comprising a first object 33 with pores of larger diameter in contact with a second object 31 with pores of smaller diameter which is in contact with the electrolyte 13. As shown, the anodic reactant feeder consists of a finely porous steel plate 31 and a porous steel plate or grid 33 and the cathodic reactant feeder consists of a finely porous carbon plate 41 and coarsely porous carbon plate 43. Container 11 is made of a Ni/Fe alloy with its interior coated with Al and exterior end surfaces coated with Ag to ensure good contact between cells. The electrolyte 13 is a sintered polycrystalline plate of Li 2 O-0À99, Na 2 O 4 -9.99 and Al 2 O 3 -89À02 wt. per cent. The active materials being Na and S or Na 2 S 5 containing finely-divided C. Reference has been directed by the Comptroller to Specifications 1,137,079, 1,137,080, 1,142,798 and 1,142,799. |
