Composited molybdenum oxide and amorphous carbon (MoO3/C) as anode material for lithium ion batteries has been successfully synthesized by calcining polyaniline (PANI) doped with ammonium heptamolybdate tetrahydrate (AMo). The as-prepared electrode material was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and field emission scanning electron microscopy (FE-SEM). The electrochemical performance of the anode was investigated by galvanostatic charge/discharge, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The MoO3/C shows higher capacity, better cyclic performance and rate performance than pristine MoO3. The electrochemical tests at different temperature were also conducted for investigating the temperature dependence of electrochemical performance for MoO3/C. The result indicates that the electrochemical performance at low temperature is mainly limited by the low kinetics of lithium ions diffusion and the high charge transfer resistance.
Keywords:lithium ion battery; molybdenum trioxide; anode material; nanocomposite; temperature dependence
