TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preparation (Claimed): A zirconium salt or an oxyzirconium salt is hydrolyzed in a raw material solution in a solvent and nitrogen containing organic compound to obtain a hybrid compound solution. The raw material solution is heated at 50 degrees C. The solvent is removed from the hybrid compound solution to obtain a hybrid compound, and contacting the hybrid compound with alkali to obtain a solid electrolyte.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The raw material solution contains a salt of an alkali earth metal, aluminum or a rare earth metal, where the alkali contains a hydroxide or oxoacid-salt of an alkali earth metal, aluminum, silicon, boron or tungsten.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compounds: The nitrogen containing organic compound contains a polydiallyldimethylammonium salt, a hydroxide, polyallylamine, an imidazole ring or a polyvinyl pyrrolidone. The solvent includes water, polyvinyl alcohol, a zirconium salt or an oxyzirconium salt. EXAMPLE - The example illustrates the manufacturing of the solid electrolytes. 50 cc of a 7 wt.% of aqueous solution of polyvinyl alcohol were mixed with 20 wt.% of an aqueous solution of polydiallyldimethylammonium chloride as a nitrogen containing organic compound. 12 g of 16.7 wt.% of an aqueous solution of zirconium oxy-chloride octahydrate were mixed while the mixture was heated at 50 degrees C under stirring for one hour to receive a raw material solution. The raw material solution was degassed and then poured over a polyester film, on which a flat and smooth base of a coating unit was equipped with a blade. The solution of the hybrid junction was heated at 50 degrees C and the water was removed. The temperature of the base was increased to 140-150 degrees C for one and a half hour. Subsequently, diaphragm formed on the base, which was replaced, and washed, after dipping into 1.67 wt.% aqueous ammonia solution for two hours at ambient temperature, and then for 30 minutes with hot water at 60-70 degrees C and then heated at 120 degrees C for one hour.
