Abstract: We report a facile method to prepare nanoarchitectured metal oxides/graphene hybrids as both positive and negative electrodes for Li-ion batteries. The metal oxides/graphene hybrids were synthesized by deposition of metal oxides and exfoliation of graphene sheets in a one-step electrochemical process. The hybrid electrodes showed high specific capacities with excellent cycling stability. For example, the Fe2O3/graphene anode was able to deliver a discharge capacity of up to 894 mA h g−1 during the 50th cycle at 0.3 C. Co3O4/graphene depicted a discharge capacity of 880 mA h g−1 during the 40th cycle at 0.3 C. The V2O5/graphene cathode delivered a discharge capacity of 208 mA h g−1 during the 100th cycle at 6.8 C.
