▎ 摘　　要

NOVELTY - The three-dimensional graphene structure comprises graphene walls surrounding pores. The graphene walls are between 1 and 10 layers of graphene sheets. A silicon particle is housed within one of the pores. The diameter of the silicon particle, when fully expanded, is less than the diameter of the pore. The graphene structure further comprises surface defects, a catalytic material attached to the structure via the surface defects, and voids. The graphene walls have a thickness of less than 20 graphene monolayers, preferably 6-10 graphene monolayers. USE - The three-dimensional graphene structure is useful in a lithium ion anode (claimed) and for electro and heterogeneous catalysis, nanoelectronics, supercapacitors and lithium ion batteries. ADVANTAGE - The decoratable, three-dimensional graphene structure: can be formed in a cost-effective manner with specific, controlled morphology; and improves battery performance. DETAILED DESCRIPTION - The three-dimensional graphene structure comprises graphene walls surrounding pores. The graphene walls are between 1 and 10 layers of graphene sheets. A silicon particle is housed within one of the pores. The diameter of the silicon particle, when fully expanded, is less than the diameter of the pore. The graphene structure further comprises surface defects, a catalytic material attached to the structure via the surface defects, and voids. The graphene walls have a thickness of less than 20 graphene monolayers, preferably 6-10 graphene monolayers. The graphene structure is a non-planar non-contiguous graphene structure. The silicon particle is further housed within one of the voids. No solid portion of the structure has a thickness of greater than 50 graphene monolayers. INDEPENDENT CLAIMS are included for: (1) a method for forming three-dimensional graphene structure; and (2) a lithium ion anode. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic cross sectional view of a three-dimensional graphene structure.
