Nowadays, great efforts have been devoted to prepare free-standing and binder-free metal oxide/graphene hybrid electrodes for LIBs.Generally, graphene was aligned and tightly compacted in the hybrid films, which greatly prohibited the electrolyte diffusion.It is still a great challenge to construct pore-enriched hybrid films with high mass loading and uniform distribution of metal oxide for enhancing Li storage performance Herein, flexible free-standing hollow Fe3O4/graphene (H-Fe3O4/GS) films were fabricated through vacuum filtration and thermal reduction process, in which graphene formed a three-dimensional conductive network, with hollow and porous Fe3O4 spindles being captured and distributed homogeneously.
