Abstract This paper reports a study on the electrochemical performance of vanadium trioxide (V 2 O 3 ) nanowire arrays as a cathode material for Li-ion battery. V 2 O 3 nanowire arrays are formed via thermal treatment of ammonium vanadium bronze (NH 4 V 4 O 10 ) nanowires in a 5% H 2 and 95% Ar atmosphere. X-ray diffraction confirms the thermal reduction. The V 2 O 3 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 .

三氧化钒纳米线阵列作为锂离子电池正极材料

摘要 本文报道了三氧化钒（V 2 O 3 ）纳米线阵列作为锂离子电池正极材料的电化学性能研究。V 2 O 3 纳米线阵列是通过在 5% H 2 和 95% Ar 气氛中热处理铵钒青铜 (NH 4 V 4 O 10 ) 纳米线形成的。X 射线衍射证实了热还原。V 2 O 3 纳米线阵列作为锂离子电池的电极表现出高可逆容量和优异的长期循环稳定性。在前 20 个循环中，放电容量从 243 增加到 428 mAh g -1。100 次循环后，在 30 mA g -1 的电流密度下仍保持 444 mA h g -1 的稳定容量。
