NOVELTY - A lithium-sulfur battery positive pole material preparation method involves mixing sulfur powder and organic amine to prepare first dispersion liquid, where weight-volume ratio of sulfur and organic amine is 0.05-0.4 g:1 ml, dispersing graphene into an organic solvent to prepare second dispersion liquid, dripping the first dispersion liquid to the second dispersion liquid, and uniformly mixing to form third dispersion liquid, adding water or acid liquor to the third dispersion liquid, performing solid-liquid separation on the third dispersion liquid, and drying to obtain finished product. USE - Method for preparing a lithium-sulfur battery positive pole material. ADVANTAGE - The method enables preparing the lithium-sulfur battery positive pole material in a simple, rapid and efficient manner. DETAILED DESCRIPTION - A lithium-sulfur battery positive pole material preparation method involves mixing sulfur powder and organic amine to prepare first dispersion liquid, where the weight-volume ratio of sulfur and the organic amine is 0.05-0.4 g:1 ml, dispersing graphene into an organic solvent to prepare second dispersion liquid, where the weight-volume ratio of the graphene and the organic solvent is 0.0005-0.02 g:1 ml, dripping the first dispersion liquid to the second dispersion liquid, and uniformly mixing to form third dispersion liquid, adding water or acid liquor to the third dispersion liquid, and continuing to stir, carrying out solid-liquid separation on the third dispersion liquid, and drying to obtain finished product.
