ABSTRACT:
The present invention pertains to solid composite cathodes which comprise (a) an electroactive sulfur-containing cathode material which, in its oxidized state, comprises a polysulfide moiety of the formula, --S.sub.m --, wherein m is an integer from 3 to 10; and (b) a cationic polymer comprising quaternary ammonium salt groups. The present invention also pertains to electric current producing cells comprising such solid composite cathodes, and methods of making such solid composite cathodes and electric current producing cells.
