The invention relates to the technical field of nanomaterial preparation, in particular to a method for preparing graphene powder. The method comprises the following steps: (1) preparing a graphene oxide solution; (2) adding organic small molecules to the graphene oxide solution, stirring, and drying to obtain graphite oxide containing organic small molecules; (3) drying the graphite oxide containing Graphite oxide with small organic molecules is subjected to thermal reduction treatment to obtain graphene powder. The graphene powder prepared by the method of the invention has the characteristics of high exfoliation, thin sheets, few structural defects, good order, and excellent electrical conductivity, and has great application prospects in the fields of lithium ion batteries, supercapacitors and the like. |
