Provided are cathode current collectors for use in electrochemical cells, wherein the current collector comprises a conductive primer layer applied upon a conductive support, and the primer layer comprises from about 20 to 60% by weight of a crosslinked polymeric material formed from a reaction of a polymeric material having hydroxyl groups and a crosslinking agent, about 2 to 15% by weight of a cationic polymer comprising quaternary ammonium salt groups, and about 35 to 75% by weight of a conductive filler. The present invention also pertains to methods of forming such cathode current collectors for use in electrochemical cells comprising: (i) an anode comprising lithium, and (ii) a cathode comprising an electroactive sulfur-containing material, and electrochemical cells comprising such cathode current collectors.
