ELECTROCHEMICAL CELL COMPRISING SULFUR-CONTAINING POLYMER

摘要

Provided is an 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 comprising sulfur atoms bound in the form of monovalent thiol groups -SH or thiolate groups -Sˉ or bound as divalent disulfide or polysulfide bridges -(S)m- in which m is integer from 2 to 8, and (b) optionally at least one binder. Furthermore provided are a use of inventive electrochemical cells and lithium ion batteries comprising at least one inventive electrochemical cell.
