Abstract
Provided is a composite cathode comprising (a) an electroactive sulfur-containing material; (b) a crosslinked polymer formed from a reaction of a polymeric material having carboxyl groups and a crosslinking agent; and (c) a conductive filler. The crosslinked polymer improves the flexibility, adhesion, and cycle life of the composite cathode in electrochemical cells comprising the cathode. Also provided are electrochemical cells comprising such cathodes and methods for preparing such cathodes and electrochemical cells.
