Hierarchical NiCo2O4@MnMoO4 core-shell nanomateriat on nickel foam was designed via a facile hydrothermal method. A possible growth mechanism of the MnMoO4 is in which the molybdenum acid radical captures part manganese ions of the MnMoO4 nanoflowers. When regarded as binder-free electrodes for supercapacitors (SCs), such special NiCo2O4@MnMoO4 core-shell hybrid electrodes exhibit ultra-high specific capacitances several times larger than a pristine NiCo2O4 electrode. The electrodes possess high specific capacitance of 1118 F g(-1) at a current density of 1 A g(-1) and excellent cycling stability (5000 cycles). This remarkable electrochemical performance is ascribed to the effective combination of two electroactive materials and the rational array configuration.
