Abstract

The present invention relates to a sulfur-carbon composite and a lithium-sulfur battery comprising the same and, more particularly, to a sulfur-carbon composite and a lithium-sulfur battery comprising the same, the composite comprising: a porous carbon material; and sulfur at at least a part of the surface and the inside of the porous carbon material, wherein the porous carbon material includes ion conductive polymer-containing coating layers on the inner and the outer surface thereof. The present invention includes the ion conductive polymer coating layers on the surfaces of the porous carbon material to improve the conduction of lithium ion to the cathode, thereby enhancing the capacity and lifespan characteristics of the lithium-sulfur battery.
