▎ 摘  要

NOVELTY - A graphene-polyaniline-sulfur composite material is prepared by adding graphene oxide in an acidic medium, reducing the graphene oxide into graphene, polymerizing aniline monomer into polyaniline, oxidizing and uniformly distributing sulfur particles on layer of graphene conductive polyaniline. USE - Graphene-polyaniline-sulfur composite material for use in lithium-sulfur batteries (claimed). ADVANTAGE - The composite material has low energy consumption, simple operation, better controllability and high yield. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene-polyaniline-sulfur composite material which involves dispersing graphene oxide in water to obtain uniform graphene oxide solution, dissolving aniline in hydrochloric acid solution to form aniline salt solution, mixing graphene oxide solution and aniline salt solution to obtain mixed solution, dissolving sodium thiosulfate and solid in water to obtain sodium thiosulfate solution, adding resulted solution with mixed solution, stirring at low temperature, settling and separating precipitate, washing and drying the separated particles to obtain a finished product.
