ABSTRACT:
A solid electrolyte composite is provided which is suitable for use as the separating member between a sodium reservoir source and a sulfur reservoir source in a sodium-sulfur battery; the solid electrolyte composite is manufactured by providing a membrane of a crystalline ionic conductive sodium polyaluminate on a portion of a porous, anhydrous crystalline supporting body consisting of alpha-Al.sub.2 O.sub.3. The sodium polyaluminate is initially applied in the form of a precursor which is then subsequently heated to form the ionic conductive crystalline sodium polyaluminate membrane.
