▎ 摘　　要

NOVELTY - Preparing ultra-fine sulfur/carbon composite material involves pre-mixing carbon material and sulfur powder in a mass ratio of 1:0.1-10 to obtain a pre-mixed material. The carbon material is porous carbon, carbon nanotubes, graphene, three-dimensional carbon skeleton and porous carbon. USE - Preparation method of ultra-thinning sulfur/carbon composite material for lithium-sulfur battery positive electrode (claimed). ADVANTAGE - The method has short time consumption, low energy consumption, no pollution, green and environment-friendly, which is good for scale production and commercial popularization, the vacuum environment is small, the energy loss is low, and the energy conversion efficiency is high. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a super-thinning sulphur/carbon composite material.
