摘要/Abstract

摘要：

采用简易的一步水热法制备了超长的VO₂(B)纳米带。对纳米带的结构、形貌、最优合成条件及电化学性能进行了研究。结果发现: 制得的VO₂(B)纳米带长度约为几十微米, 宽度为~200 nm; 且最优合成条件为在钒源与还原剂摩尔比为2:1的条件下, 200℃水热反应24 h。当该VO₂(B)纳米带被作为锂离子电池的阳极材料时, 显示出了优异的电化学性能, 尤其是循环稳定性, 循环500周后的电容量损失率仅为10.41%, 极大的解决了钒类纳米材料作为锂离子电池阳极材料时稳定性差的问题, 提高了其成为锂离子电池阳极材料的可能性。

Abstract:

Ultra-long VO₂(B) nanobelts were fabricated by a facile one-step hydrothermal treatment. It was found that the nanobelts were about ~200 nm in width and dozens of microns in length. Being used as a cathode material, the VO₂(B) nanobelts show superior rate capability, with discharge capacities of ca. 425, 175, 125, 90, 75 and 50 mAh/g at 50, 100, 200, 500, 1000 and 2000 mA/g, respectively. More importantly, excellent cycling stability without considerable capacity loss (10.41%) for 500 cycles is observed. The present study implied that the unique ultra-long nanobelts morphology and its intrinsic structural features are responsible for their excellent structure stability, and thus resulting in superior electrochemical performance.
