Abstract

The present invention relates to electrode materials for electrical cells, containing, as component (A), at least one polymer including polymer chains formed from identical or different monomer units selected from substituted and unsubstituted vinyl units and substituted and unsubstituted C2-C10-alkylene glycol units and containing at least one monomer unit -M1- including at least one thiolate group —S− or at least one end of a disulfide or polysulfide bridge —(S)m— in which m is an integer from 2 to 8, the thiolate group or the one end of the disulfide or polysulfide bridge —(S)m— in each case being bonded directly to a carbon atom of the monomer unit -M1-, and, as component (B), carbon in a polymorph containing at least 60% sp2-hybridized carbon atoms. The present invention also relates to electrical cells containing the inventive electrode material, to specific polymers, to processes for preparation, and to uses of the inventive cells.
