▎ 摘　　要

Well crystallized Fe2O3 with the particle size mainly concentrated around 35-40 nm combined with graphene is fabricated under solvothermal conditions. The optimized Fe2O3/GH-2 composite sample possessing 49.7 wt% Fe2O3 has a high specific BET surface area of 215.3 m(2) g(-1). When used as a supercapacitor electrode, the capacitances are admirable 2310 F g(-1) at 5 mV s(-1) and 615 F g(-1) at an amazingly high current density of 100 A g(-1). When used as an anode material for asymmetric hybrid capacitors, the composite shows a promising future for energy storage with high energy density, high power density and excellent cycle life.
