▎ 摘　　要

NOVELTY - An electro- and thermo-conductive graphene-sulfur composite material (100) comprises a porous graphene structure comprising a network of graphene layers (110) which are attached to one another through a carbonized organic polymer bridging agent (120), and a sulfur material (130) impregnated within the porous graphene structure. USE - Electro- and thermo-conductive graphene-sulfur composite material is used for cathode of lithium-sulfur battery (all claimed). ADVANTAGE - The electro- and thermo-conductive graphene-sulfur composite material economically produces lithium-sulfur battery having high theoretical capacity, due to abundant resources of sulfur. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of electro- and thermo-conductive graphene-sulfur composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene-sulfur composite material.
