ABSTRACT:
A rechargeable battery includes a solid protonically conducting electrolyte comprising hydrated aluminum oxide. Two embodiments of the battery are disclosed. In both embodiments, the negative electrode comprises a metal hydride such as PdH.sub.x. In one embodiment, the positive electrode comprises a metal such as platinum which serves as a catalyst for oxygen reduction reactions. In the other embodiment, the positive electrode comprises an oxide or hydroxide of a transition metal element. The second-mentioned positive electrode is capable of reversible electrochemical change and charge storage. Both battery embodiments can be made in thin-film form to serve as a constituent of an integrated-circuit assembly.
