▎ 摘　　要

NOVELTY - The method for producing multi-stage structure graphene material, involves filtering the graphene solution to form graphene film, mixing oxidized graphene solution with electrolyte to obtain mixed solution, treating the mixed solution with graphene film, filtering to obtain mixed graphene material, carrying out lyophilization reaction of mixed graphene material to obtain multi-stage structure graphene material. USE - Method for producing multi-stage structure graphene material (claimed). ADVANTAGE - The method reduces the non-compactness during construction of the graphene material, reduces the process and structure and reduces the function of conflict between different structures and properties of different materials.
