▎ 摘　　要

NOVELTY - Preparing lithium sulfur battery anode material comprises (a) adding the graphene, nitrogen-containing organic matter, transition metal salt and dispersant in aqueous solution, dispersing uniformly to obtain suspension, (b) spray drying the suspension, (c) calcining the material obtained after spray drying at a high temperature in an argon atmosphere to obtain transition metal-doped graphene-carbon nanotube composite microspheres, and (d) placing the transition metal-doped graphene-carbon nanotube composite microspheres and sulfur powder in a ball-milling jar for ball-milling, placing in a reactor filled with argon to react. USE - The method is useful for preparing lithium sulfur battery anode material. ADVANTAGE - The method uses simple raw materials to realize the in-situ growth of carbon nanotubes on graphene nanosheets by a spray drying method. The prepared lithium-sulfur battery cathode material solves the shuttle effect of lithium polysulfides (LiPSs), has good cycle performance, and the preparation method is simple, easy to implement, and easy to mass-produce. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for lithium sulfur battery anode material prepared by the above-mentioned method.
