NOVELTY - This invention relates to a method for preparing a graphene sheet, comprising: providing a carbon precursor and a filler; using the carbon precursor as the binder to be well mixed with the filler; carrying out a shaping process to produce a composite; under an atmosphere, subjecting the composite material to thermal treatments of different temperatures to increase its conductivity and properly adjust the binding strength; and converting the composite material carbon to provide the excellent graphite crystallinity to produce a layered graphite structure to obtain a graphene sheet precursor. In addition, the graphene sheet precursor can be subjected to an electrochemical process to obtain the high quality graphene. Therefore, the purposes of rapid mass production, reduced production costs and high quality graphene sheets can be met.
