Abstract
An electrolyte glass for use as the solid electrolyte in high-temperature galvanic batteries, for example a sodium-sulfur battery. The glass electrolyte has relatively low resistivity and high corrosion resistance and is easily worked by glass manufacturing techniques. The composition of the glass electrolyte according to the invention is defined by xNa.sub.2 O.multidot.ySiO.sub.2 .multidot.zAl.sub.2 O.sub.3.
