▎ 摘　　要

NOVELTY - The diaphragm has a diaphragm base arranged with a covering layer that is formed of graphene-sulphide hetero-junction material. Mass ratio of the graphene-sulphide hetero-junction material is about 0.5-15:1. The graphene-sulphide hetero-junction material is formed of titanium disulphide material, vanadium disulfide material and sulfide material. USE - Diaphragm for a lithium-sulphur battery (claimed). ADVANTAGE - The diaphragm increases polysulfide shuttle effect and improves utilization rate and electrochemical and aerodynamic performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a lithium-sulphur battery (2) a lithium-sulphur battery manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a photograph of a diaphragm.
