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, —Sm—, wherein m is an integer from 3 to 10; and (b) a non-electroactive particulate material having a strong adsorption of soluble polysulfides. 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.
