▎ 摘　　要

NOVELTY - Preparing reduced graphene oxide modified vulcanized-antimony trisulfide cell cathode material comprises (i) adding antimony trisulfide (Sb2S3) powder to absolute ethanol, dispersing in graphene oxide solution and stirring until the solution is uniformly stabilized to obtain precursor solution; (ii) transferring precursor solution obtained in step (i) into hydrothermal reaction vessel, heating the reaction and cooling to room temperature to obtain suspension; and (iii) filtering suspension obtained in step (ii), washing and drying. USE - The method is useful for preparing reduced graphene oxide modified vulcanized-antimony trisulfide cell cathode material. ADVANTAGE - The prepared reduced graphene oxide modified vulcanized-antimony trisulfide cell cathode material has good electrochemical sodium storage performance and is a good anode material for sodium ion batteries. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) reduced graphene oxide modified vulcanized-antimony trisulfide cell cathode material, prepared by above mentioned method; and (2) sodium-ion battery cathode sheet, prepared by mixing battery cathode electrode material uniformly with adhesive and conductive agent, coating on copper foil, drying and rolling.
