A sulfur-polypyrrole composite cathode with a core-shell structure consisting of spherical sulfur particles coated with polypyrrole has been developed. The conductive polypyrrole coating on the sulfur facilitates fast electron transport enabling the material with superior electrochemical stability, rate capability, and cyclability in lithium-sulfur batteries.
