说明书摘要	The present invention provides a method for preparing graphene, including reacting graphite in an acid solution in which an oxidant is present so as to obtain a graphene. Compared with the prior art, the advantages of the present invention reside in that, the graphene prepared by the method of the present invention has excellent quality and substantially increased yield and production rate, as compared with mechanical stripping, epitaxial growth, and chemical vapor deposition; and the graphene prepared by the method of the present invention has significantly improved quality, substantially reduced structural defects, and significantly increased conductivity, as compared with oxidation-reduction preparation in the solution-phase; besides, the method is also advantageous for a simple process, mild conditions, low cost, and very easy for scale production. The graphene prepared by the present invention has very broad prospects in the fields of lithium-ion batteries, supercapacitors, functional composite materials, transparent conductive films, and microelectronic devices, etc.
