SULFUR-CARBON COMPOSITE MATERIAL, ITS APPLICATION IN LITHIUM-SULFUR BATTERY AND METHOD FOR PREPARING SAID COMPOSITE MATERIAL

摘要

The present invention provides a sulfur-carbon composite material, said composite material comprising a porous carbon substrate containing both micropores and mesopores and sulfur, wherein the sulfur is only contained in the micropores of the carbon substrate. Moreover, a lithium- sulfur battery with its cathode comprising said sulfur-carbon composite material and the method for preparing such material is also provided.
