3D hollow‐carbon‐spheres/graphene‐flake hybrid nanostructures are controllably prepared from a polypropylene/montmorillonite/Fe3O4 composite by a self‐assembly and subsequent carbonization process. More importantly, in the resultant hollow‐carbon‐spheres/graphene‐flake hybrid structures, the monodispersed small hollow carbon spheres can be distributed on the graphene flake with controllable density. The obtained hollow‐carbon‐spheres/graphene‐flake hybrid nanostructures show improved performance in lithium‐ion batteries.
