▎ 摘　　要

NOVELTY - Preparing graphene modified silicon carbon anode material comprises (i) adding silicon powder and graphite fine powder to graphene oxide dispersion, adding dispersant, carrying out ultrasonic dispersion treatment to form suspension, where ratio of graphene oxide, silicon powder and graphite micropowder is 1:3-6:10-20; and (ii) spray-drying suspension obtained in step (ii) and pelletizing and heat-treating at 500-800 degrees C in reducing atmosphere to obtain graphene-coated silicon powder. USE - The method is useful for preparing graphene modified silicon carbon anode material.
