▎ 摘　　要

NOVELTY - Synthesizing stannous sulfide/graphene cathode material by one-step solid phase method comprises (i) mixing uniformly an organotin compound and a sulfur source by grinding; the mass ratio of the organotin compound to the sulfur source is 1: (0.5-4), (ii) heating the mixture from room temperature to 600-800℃ at a heating rate of 2-5℃ minutes -1 in a vacuum or argon atmosphere, and maintaining the temperature for 2-5 hours to obtain stannous sulfide/graphene, stannous sulfide/graphene is composed of stannous sulfide particles and graphene sheets, the morphology of the stannous sulfide/graphene is a flower-shaped spherical structure formed by gathering nanosheets, and the diameter of the particles is 7-8 microns. USE - The method is useful for synthesizing stannous sulfide/graphene cathode material by one-step solid phase method. ADVANTAGE - The method has high purity, has excellent electrochemical performance in the lithium ion batteries, is simple, has positive meaning for widening the selection range, is low cost and has wide application prospects.
