Abstract

A sulfur-carbon composite and a lithium-sulfur battery including the same, and in particular, to a sulfur-carbon composite comprising a porous carbon material; and sulfur on at least a part of an inside and outside surface of the porous carbon material, wherein the inside and outside surface of the porous carbon material include a coating layer comprising an ion conducting polymer, and a lithium-sulfur battery including the same. Also provided is an ion conducting polymer coating layer on a porous carbon material surface which thereby improves a lithium ion conducting property to a positive electrode, and as a result, may enhance capacity and life time properties of a lithium-sulfur battery.
