In this study,a self-supporting CoMoO₄@MnMoO₄ composite electrode material on a nickel foam substrate was prepared through a two-step hydrothermal method followed by annealing and calcina-tion treatments.The phase composition and microstructure of the electrode material were investigated using X-ray diffractometer(XRD)and scanning electron microscope(SEM).The electrochemical perfor-mance of the electrode material was evaluated using an electrochemical workstation.The results reveal that the CoMoO₄@MnMoO₄ electrode material possesses a dense nanosheet structure with numerous nanopar-ticles attached on the surface.The abundant nanosheet interlayer pores significantly facilitate ion transport and provide ample active sites,thereby promoting Faradaic redox reactions between the active materials and electrolyte.The electrode demonstrates an charge/discharge duration of 1500 s and achieves an exceptional specific capacitance of 726.6 C/g at a current density of 1 A/g.Furthermore,the CoMoO₄@MnMoO₄ com-posite electrode material shows significantly better rate performance than the individual CoMoO₄ and MnMoO₄ electrodes.The CoMoO₄@MnMoO₄ composite electrode material exhibits superior electrochemi-cal performance compared to its individual-components.
