3D graphene interconnected frameworks homogeneously connected with a few‐layer graphene film (3DG/FLG) constitute a novel hierarchical hybrid structure for anodes in lithium‐ion batteries. The pore‐rich 3D graphene network is favorable for Li + diffusion and electron transport, and the FLG is a non‐metallic current collector that effectively collects/transports charge carriers from/to the 3D graphene network and provides an excellent scaffold to support the 3DG.
