Fe 2 O 3 /reduced graphene oxide composite (FFGC) was fabricated by a hydrothermal method for the exploration of electrochemical energy storage, where the Fe 2 O 3 nanoparticles (NPs) loaded onto the surface of reduced graphene oxide (rGO) sheet uniformly. Interestingly, the TEM image showed that visible micro-cracks were appeared on the surface of flower-like Fe 2 O 3 NP, which did not interfere with its stably crystalline structure. Herein, FFGC was investigated as anode material for lithium-ion battery (LIB) as well as electrode material for supercapacitor (SC). For instance, the specific discharge capacity was of 1366 mAh g-1 at 0.1 A g-1 in LIB case, while the specific capacitance of 318.9 F g-1 at 0.1 A g-1 in SC experiment. On the other hand, FFGC exhibited the excellently steady performance in either LIB or SC experiment. Those results suggest the roseate future of FFGC in the application of energy issues.
