▎ 摘　　要

NOVELTY - Graphene composite material preparation involves adding tin powder, sulfur powder and expanded graphite into a ball mill tank with stirring, and then milling by using medium barrier discharge plasma assisted high-energy ball milling to obtain graphene composite material. The tin powder and the sulfur powder are provided in a molar ratio of 1:1-1:4. USE - Method for preparing graphene composite material used for manufacturing lithium or sodium ion battery anode material (claimed). ADVANTAGE - The method prepares the graphene composite material in a simple and cost-effective manner with excellent electrochemical properties, high capacity and excellent cycle performance and rate performance, and can be prepared in a simple, cost-effective, and eco-friendly manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic scanning electron microscopic image of the prepared graphene composite material.
