    Abstract: Production of a flexible battery separator, according to one embodiment, by dip-coating an electrode such as a silver or zinc electrode in a mixture of a major portion of an inorganic or ceramic separator material, a minor portion of potassium titanate, and a minor portion of a mixture of organic substances including an organic polymer, e.g., polyphenylene oxide, and a material or ester derived from certain acids such as azelaic acid, e.g., di-isooctyl azelate or polypropylene polyazelate, such mixture of organic substances being dissolved in a suitable solvent such as chloroform. The electrode is placed in the mixture, preferably maintained under vibration, and stirred, the electrode and applied coating are removed from the mixture, and the coating is air-dried to remove solvent and is cured at elevated temperature. Alternatively, such a flexible separator can be formed on any suitable supporting surface, such as glass plate, and the resulting flexible separator stripped from such plate to produce a flexible porous, substantially inorganic separator membrane for incorporation between the electrodes of a battery. Alternatively, a flexible porous substrate or matrix, preferably in the form of a compartment for insertion therein of a battery electrode, can be placed in the above-noted mixture of inorganic material and organic substances, the substrate and applied coating removed from the mixture, and the coating dried to remove solvent and cured at elevated temperature. In each case, the separator film (a) applied directly on the battery electrode, or (b) cast as a flexible free film, or (c) coated on or impregnated into a flexible matrix, has improved high flexibility and low resistivity properties, and has high resistance to alkali and to elevated temperatures, and is smooth and uniform in thickness.

    Abstract: PRODUCTION OF AN IMPROVED SEPARATOR HAVING EXTENDED LIFE, PATRICULARLY OVER A LARGE NUMBER OF DEEP DISCHARGE CYCLES WHEN EMPLOYED IN A HIGH ENERGY DENSITY BATTERY, SUCH AS A SILVER-ZINC BATTERY, BY OVERCOATING A RIGID INORGANIC SEPARATOR, WITH A THIN LAYER OF A FLEXIBLE SUBSTANTIALLY INORGANIC SEPARATOR FILM, THE INORGANIC MATERIAL OF THE RIGID SEPARATOR AND OF THE FLEXIBLE OVERCOATING BEING THE SAME, OR DIFFERENT, INORGANIC MATERIALS. THUS THE INORGANIC SEPARATOR MATERIAL FOR THE RIGID SEPARATOR AND FLEXIBLE OVERCOATING CAN BE A SOLID SOLUTION OF MAGNESIUM SILICATE AND IRON SILICATE; OR THE INORGANIC MATERIAL OF THE RIGID SEPARATOR CAN BE THE LATTER INORGANIC MATERIAL AND THE INORGANIC MATERIAL OF THE FLEXIBLE SEPARATOR CAN BE ZIRCONIA.

    Abstract: 1,142,586. Sintered ion conducting membranes. DOUGLAS AIRCRAFT CO. Inc. 11 Feb., 1966 [26 May, 1965], No. 6223/66. Heading C1J. An ion conducting membrane is formed by sintering a mixture of (1) a water-insoluble hydrous metal oxide plus an inorganic acid or a water-insoluble acid salt, and (2) a material retaining a sufficient amount of water and providing a water v.p. of 10-200 mm. at 100‹ C. when the membrane is incorporated in a fuel cell, treating the sinter with an inorganic acid and re-sintering. Specified are: Materials-alumino silicates, activated alumina, Al 2 (Se 4 ) 3 , H 2 SiO 3 , SiO 2 (gel or colloidal), P 2 O 5 , Cu(So 4 ) 3 , CaCl 2 and NH 4 acid phosphate; Acids-boric, phosphoric, molybdic, phosphomolybdic, tungstic and sulphuric; Oxides- Zr, Ti, Sb, W, Si, Sc, Bi, V, Mo, Cr and Al; Salts-Zr phosphate, and sulphate, Ti phosphate and molybdate, Sn phosphate and Th phosphate. The terms " hydrous metal oxide " and " acid salt " are defined.
