	Abstract: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.

	Abstract:A series of LiNi1/3-xCo1/3Mn1/3+xO2(x=0, 1/18, 1/15, and 1/12) cathode materials was successfully synthesized via electrospinning. The samples were characterized using X-ray diffraction, scanning electron microscopy, and electrical conductivity measurements. In addition, 2025-type coin cells containing LiNi1/3-xCo1/3Mn1/3+xO2 cathode materials were characterized using cyclic voltammetry and galvanostatic charge/discharge measurements. The Ni-Mn content (x) significantly affected the electrochemical properties of the electrospun samples, although electrospinning did not alter the samples' micromorphologies. The specific capacities, rate performances, cycle stabilities, and conductivities of the LiNi1/3-xCo1/3Mn1/3+xO2(0≤x≤1/15) samples increased with increasing x. The cation mixing of LiNi1/3-xCo1/3Mn1/3+xO2(0≤x≤1/15) was reduced when the Ni content decreased, indicating that the structural stability was enhanced. When x was increased further, the electrochemical performance of LiNi0.25Co0.33Mn0.42O2 was attenuated. The excess x value (x=1/12) in LiNi1/3-xCo1/3Mn1/3+xO2 prepared by electrospinning debases the structure stability possibly.
