Three-dimensional NiO/CoMoO₄ composite electrode materials were successfully prepared by two-step hydrothermal and high temperature annealing. The structure, surface morphology and electrochemical performance were characterized using X-ray diffraction, scanning electron microscopy, transmission electron microscopy and electrochemical method. The results showed that NiO/CoMoO₄ composite materials owned typical nanowires/nanosheet structure, which were different from needle-like morphology of NiO. The structure provided more active sites for the active substance, compared with pure NiO. The specific capacitance of the composites could reach 2253 F/g at the current density of 0.3 A/g, which was higher than that of pure NiO. It displayed good cycling stability with 92% capacitance retention after 2000 cycles due to the synergistic effect between NiO and CoMoO₄.
