Completely solid state lithium and sodium batteries have been developed, operating in the approximate temperature range from room temperature to 145 ° C (limited by electrode / electrolyte melting points), including the power energy densities far exceed the high temperature battery systems of the current art. The preferred battery comprises a lithium or solid sodium electrode (12), a polymer electrolyte (15) such as polyethylene oxide doped with lithium triflate (PEO8LiCF3SO3), as well as composite positive electrodes (14). solid state, containing a polymer organosulfur electrode, (SRS) n, and carbon black, dispersed in a polymer electrolyte. |
