Abstract: The present invention relates to electrochemical cells comprising (A) at least one cathode comprising at least one lithium ion-containing transition metal compound, (B) at least one anode, and (C) at least one layer comprising (a) at least one sulfur-containing polymer (a) comprising sulfur atoms bound in the form of monovalent thiol groups —SH or thiolate groups —S− or bound as divalent disulfide or polysulfide bridges —(S)m— in which m is an integer from 2 to 8, and (b) optionally at least one binder. The present invention further relates to the use of inventive electrochemical cells, and to lithium ion batteries comprising at least one inventive electrochemical cell.
