An ionic liquid derived Co 3 O 4 /carbon nano-onions composite has been prepared by carbothermal reduction followed by oxidation. The introduction of carbon nano-onions improves the conductivity and structural stability of Co 3 O 4  electrode material. Electrochemical measurements indicate that the redox reversibility is significantly improved. The Co 3 O 4 /carbon nano-onions composite shows a large specific capacitance of 402.35 F g –1  at a current density of 0.5 A g –1 . After 9000 cycles, the specific capacitance retention remained 76% at 1 A g –1 . The as-prepared Co 3 O 4 /carbon nano-onions composite delivers superior capacitive performance with good rate capability, large specific capacitance, and excellent cyclic performance, showing great application potential for high-performance electrochemical supercapacitors.
