Lithium‐Ion Batteries Novel hierarchical flower‐ and sheet‐type NiCo 2 O 4 architectures are electrochemically synthesized in‐situ on 3D graphene‐coated nickel foam (3D‐GNF) as binder‐free electrodes for lithium‐ion batteries (LIBs). The flower and sheet morphologies show excellent reproducibility under constant voltage and constant current conditions, respectively. High discharge capacities are obtained for both hybrid electrodes. In particular, flower‐structured NiCo 2 O 4 shows much better cycling stability owing to unique electrode structure and the synergistic effect of 3D‐GNF as a scaffold electrode.
