▎ 摘  要

NOVELTY - The material has a porous material comprising sulfur/carbon composite material porous particles, where a graphene sheet is coated on an outer surface of the sulfur/carbon composite material porous particles. The graphene sheet is covered on graphene/porous carbon composite material particles to form graphene conductive network. The graphene conductive network is formed with a porous grading core-shell structure. USE - Graphene coated sulfur/porous carbon composite anode material for a lithium ion battery. ADVANTAGE - The material has high capacity, long cycle life and better multiplying performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene coated sulfur/porous carbon composite anode material manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene coated sulfur/porous carbon composite anode material.
