Abstract
The present invention provides all solid-state lithium and sodium batteries operating in the approximate temperature range of ambient to 145.degree. C. (limited by melting points of electrodes/electrolyte), with demonstrated energy and power densities far in excess of state-of-the-art high-temperature battery systems. The preferred battery comprises a solid lithium or sodium electrode, a polymeric electrolyte such as polyethylene oxide doped with lithium triflate (PEO.sub.8 LiCF.sub.3 SO.sub.3), and a solid-state composite positive electrode containing a polymeric organosulfur electrode, (SRS).sub.n, and carbon black, dispersed in a polymeric electrolyte.
