The specific capacity of carbon-based anode material is low and can't meet the demand of battery with high energy density.To search for the anode material of battery with high capacity and long cycle life,the CoMoO4 electrode was prepared through hydrothermal method.The structure and morphology of as-prepared material were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).The electrochemical performances were investigated using cyclic voltammetry and galvanostatic charge/discharge measurement.The results showed that as it was applied to anode forlithium-ion batteries (LIBs),the initial reversible capacity was 1 403.6 mAh/g and the initial coulombic efficiency was up to 146.5%,and the specific reversible capacity retained up to 793.6 mAh/g even after 50 cycles at a current density of 100 mA/g.Furthermore,as it was applied into the anode material of sodium ion battery,the initial specific reversible capacity was only 314.2 mAh/g.However,the capacity retention was up to 76.4% after 50 cycles.There was no conductive and binder for the self-standing anode,and there was strong binding force between electrode material and nickel foam.Meanwhile,the excellent cycling stability was attributed to the small electrochemical transfer impedance.
