▎ 摘　　要

NOVELTY - Preparing VS4-graphene aerogel composite material comprises (a) dissolving sodium orthovanadate dihydrate and thioacetamide (C2H5NS) in deionized water to obtain uniform solution A, dissolving graphene oxide in deionized water to obtain solution B; mixing solution A and solution B to obtain uniform solution-C, and (b) transferring solution C to the reaction kettle for hydrothermal reaction to reduce graphene oxide, allowing to stand, filtering, and drying. USE - The method for preparing VS4-graphene aerogel composite material is used in lithium-sulphur battery (claimed). ADVANTAGE - The VS4-graphene aerogel composite material improves the diffusion coefficient and electronic conductivity of Li+, and improves rate performance and cycle performance of the obtained lithium-sulfur battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for lithium-sulphur battery.
