Abstract:In this paper, ammonium molybdate tetrahydrate and ethylene glycol were used to synthesize MoO2 by a simple hydrothermal method. X-ray powder diffraction (XRD), Scanning electron microscopy (SEM), electrochemical tests were applied to study the structure and electrochemical properties of the material. The results indicate that the particle size of the MoO2 nanoparticle is estimated to be 20~30 nm. And the material shows good electrochemical performance. The first discharge capacity of MoO2 is 664.3 mAh.g-1, and the initial coulombic efficiencies is as high as 94%. It also has higher capacity retention rate after 20 cycles. The MoO2 material as anode for lithium-ion batteries exhibits good storage capacity and cycle performance.
Keywords:lithium-ion batteries  anode material  MoO2  electrochemical performance
