▎ 摘  要

NOVELTY - Preparing a hydrogen bond organic framework-sulfur composite material, comprises uniformly mixing the sulfur powder, hydrogen bond organic framework material and conductive material according to a specific proportion by ball milling, stirring and reacting for a specific time at a specific temperature, and then crushing to obtain the final product. The conductive material is MXene, carbon nanotube, graphene, porous carbon and carbon black. USE - The composite material is useful as anode for preparing a lithium-sulfur battery (claimed). ADVANTAGE - The composite material: has excellent cycle life and retention rate; ensure the rich hydrogen bonding effect to absorb and desorb lithium polysulfide; and improves the lithium storage capacity and stability of the electrode; and the method is economical and has low device requirement.
