A sandwich structured composite of graphene‐wrapped Fe 3 O 4 ‐graphene nanoribbons is prepared using a facile and cost‐effective approach. The composite demonstrates a high capacity, good rate performance, and greatly improved cycling stability due to the synergistic combination of electrically conductive graphene, graphene nanoribbons, and Fe 3 O 4 . The design concept developed mitigates losses that are often seen in nanostructured systems while permitting facile ion access through the material.
