Herein, NiCo2O4@g-C3N4(C) hybrid was synthesized by growing spinel nickel cobaltite (NiCo2O4) on the carbon doped graphitic carbon nitride (g-C3N4(C)). The elegant synergy between NiCo2O4 and g-C3N4(C) leads to a high specific capacitance of 325.7 F\textperiodcenteredg1 at the current density of 1 A\textperiodcenteredg1 and an exceptional cycling stability (93.6% retention after 2000 cycles). NiCo2O4@g-C3N4(C) hybrid asymmetric capacitor was assembled and electrochemical tests showed that asymmetric capacitor possesses high power density (15.1 kW\textperiodcenteredkg1) and superior cycling stability (83.5% retention after 2000 cycles).", }
