摘要：

This paper reports a study on the electrochemical performance of vanadium trioxide (V-2O3) nanowire arrays as a cathode material for Li-ion battery. V2O3 nanowire arrays are formed via thermal treatment of ammonium vanadium bronze (NH4V4O10) nanowires in a 5% H-2 and 95% Ar atmosphere. X-ray diffraction confirms the thermal reduction. The V2O3 nanowire arrays as an electrode of lithium-ion battery exhibit high reversible capacity and excellent long-term cycling stability. The discharge capacity increases from 243 to 428 mA h g(-1) at the first 20 cycles. After 100 cycles, a stable capacity of 444 mA h g(-1) is retained at a current density of 30 mA g(-1).
