| abstract | 1,202,259. Energy storage device; capacitors; voltage variable capacitors. FORD MOTOR CO. Ltd. 21 Nov., 1967 [21 Nov., 1966], No. 52848/67. Headings H1B, H1K and HIM. An electrical energy storage device comprises a sandwich having two outer polycrystalline layers in cation exchange relationship with and separated by a polycrystalline central layer, each outer layer consisting of mobile cations in an electronically conductive lattice comprising ions of oxygen and of a metal having two different valency states, the central layer consisting of mobile cations in an electronically insulating lattice and the mobile cations in all three layers being the same. The conductive lattice may comprise ferrous and ferric oxides, the non-conductive lattice alumina and the mobile cations may be sodium potassium or lithium. The non-conductive lattice may also contain a metal having a valency of 1 or 2 e.g. magnesium or lithium. In typical Example 2 the outer layers are prepared by mixing sodium carbonate, ferric oxide, titanium dioxide and alumina with wax as temporary binder and compressing the mixture. The central layer is a eutectic mixture of alumina and beta-alumina (Na 2 O.11Al 2 O 3 ). The sandwich is wrapped in platinum foil and heated to sinter the layers together. In Example 3 the outer layers are prepared from potassium carbonate, sodium carbonate, ferric oxide and titanium dioxide and the centre layer from potassium carbonate, lithium carbonate and alumina. In Example 4 the centre layer is prepared from sodium carbonate, lithium nitrate and alumina. In Example 6 the centre layer of Example 4 is treated with potassium aluminate to replace the sodium ions by potassium. In Example 7 the centre layer of Example 4 is first treated with silver nitrate in an argon atmosphere to replace the sodium ions by silver and then with lithium chloride in an argon atmosphere to replace the silver ions by lithium. |
