# Crosslinked polythiophene compounds, sulfur-carbon composite, lithium-sulfur battery, and method of manufacturing the sulfur-carbon composite

## Abstract

Provided are a crosslinked polythiophene compound having a crosslinking structure and comprising a cationic functional group, a sulfur-carbon composite comprising a porous carbon material; a coating layer disposed on at least a surface of the porous carbon material and comprising the crosslinked polythiophene compound; and a sulfur compound present in at least a portion of the surface of the porous carbon material or inside of pores of the porous carbon material, or a surface of the coating layer, and a lithium-sulfur battery comprising the sulfur-carbon composite.
