▎ 摘　　要

NOVELTY - A sulfur electrode of lithium-sulfur battery preparing method involves coating the graphene slurry on a separator and drying to obtain a graphene/separator substrate, labeling as GN-1/polypropylene, spraying a carbon/sulfur composite dispersion onto the graphene/membrane substrate by electrostatic spraying to obtain a carbon doped sulfur composite layer/graphene layer-1/membrane layer, labeling carbon doped sulfur/GN-1/polypropylene substrate, spraying a graphene dispersion on the carbon doped sulfur/GN-1/polypropylene substrate by electrostatic spraying to obtain a graphene layer-2/carbon doped sulfur composite layer/graphene layer-1/ diaphragm layer, labeled GN-2/carbon doped sulfur/GN1/polypropylene. USE - Method for preparing sulfur electrode of lithium-sulfur battery. ADVANTAGE - The method enables preparing sulfur electrode of lithium-sulfur battery with improving the energy density, high capacity and excellent cycle stability.
