ABSTRACT:
A power cell having an anode, a cathode and a solid electrolyte is improved by having as the solid electrolyte a glass comprising either (1) from about 22 mole percent to about 47 mole percent Na.sub.2 O, from about 4 mole percent to about 9 mole percent Y.sub.2 O.sub.3 and from about 47 mole percent to about 70 mole percent SiO.sub.2 or (2) from about 34 mole percent to about 47 mole percent Li.sub.2 O, from about 5 mole percent to about 9 mole percent Y.sub.2 O.sub.3 and from about 47 mole percent to about 58 mole percent SiO.sub.2.
