摘要

以锐钛矿相TiO2粉末和氢氧化钠作原料,应用化学合成法,于高温高压反应釜中制备TiO2纳米管.TEM、XRD分析显示,所得产物为锐钛矿相四方结构的TiO2纳米管.恒流充放电、循环伏安法测试表明,该TiO2纳米管首次嵌锂容量达260 mA.h/g,可逆容量高,有希望成为未来一种较好的新型锂离子电池负极材料.

Abstract

Titanium oxide nanotubes were prepared by hydrothermal treatment of anatase-type TiO_(2) powders and NaOH solution in an autoclave.Transmission Electron Microscopy and X-ray Diffraction showed that the product is anatase-type TiO_(2) nanotubes.The constant charge-discharge current and cyclic voltammetry exhibited the TiO_(2) nanotubes have a large initial lithium insertion capacity of 260 mA·h/g and good reversibility.This study indicates that TiO_(2) nanotubes might be a good negative electrode materical for second lithium battery in the future.
