▎ 摘　　要

NOVELTY - A composite material comprises graphene as carbon source in multilayer form of two-dimensional structure, and with surface comprising sulfur molecules intercalated between layers of graphene. The layer spacing of two-dimensional structure of carbon is 0.35-1 nm, preferably 0.39-0.56 nm. The content of sulfur is 5-60 wt.%, preferably 30-40 wt.% with respect to total content of the composite material. USE - Composite material is used for electrode of lithium-sulfur battery (all claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of composite material, which involves oxidizing a carbon material having graphite structure in an acid solution, obtaining an oxide of a carbon material, mixing resultant with sulfur and an organic solvent, performing solvothermal reaction at 100-180 degrees C, cooling, washing and drying.
