Title: Polymer-sulfur composite materials for electrodes in Li-S energy storage devices

Abstract

Composite materials containing sulfurized polymers and sulfur-containing particles can be used in lithium-sulfur energy storage devices as a positive electrode. The composite material exhibits relatively high capacity retention and high charge/discharge cycle stability. In one particular instance, the composite comprises a sulfurized polymer having chains that are cross-linked through sulfur bonds. The polymer provides a matrix in which sulfide and/or polysulfide intermediates formed during electrochemical charge-discharge processes of sulfur can be confined through chemical bonds and not mere physical confinement or sorption.
