Supercapacitors have attracted great attentions for their excellent performance in the energy devices. In this work, the reduced graphene oxide (rGO) modified NiCo2O4(rGO/NiCo2O4) are fabricated by a simple hydrothermal route. After the rGO modification, the sea urchin-like structure of NiCo2O4was broken and the NiCo2O4nanowires would intertwine with each other. Benefit from the large surface areas and the active sites of this unconsolidated structure, the as-prepared rGO/NiCo2O4exhibited the excellent specific capacitance of 1003 F g−1at the current density of 1 A g−1and enhanced rate capability (89% from 1 to 10 A g−1). And the cycle stability could reach 57% retention after the 10000 cycles. The rGO/NiCo2O4composite might hold great promise for future application of the high-performance supercapacitor.
