▎ 摘　　要

NOVELTY - A graphene coated carbon microsphere material preparation method involves peeling off graphene oxide by chemical to make oxidized graphite alkene solution, and followed by preparing carbon micro-sphere by subjecting glucose, sucrose or starch as carbon source to perform hydro-thermal treatment under an acidic condition. The obtained carbon micro-sphere and oxidized graphite alkene solution are mixed to obtain uniform suspension system, followed by filtering and drying to obtain the graphene oxide coated carbon micro-ball product, which is heated under protective atmosphere. USE - Method for preparing graphene coated carbon microsphere material. ADVANTAGE - The method enables preparing graphene coated carbon microsphere material without harmful substance in an effective manner.
