Abstract
Onedimensional 1D submicronbelts of V2O5 have been prepared by a sol–gel route using V2O5 H2O2 and aniline as starting materials Thermogravimetric and differential thermal analysis Xray diffraction Fourier transform infrared spectroscopy and scanning electron microscopy were employed to characterize the samples Electrochemical behaviors as cathode material in rechargeable lithiumion batteries were investigated by galvanostatic charge–discharge measurement and cyclic voltammeter The results showed that the synthesized V2O5 appeared to be submicronbelts and orthorhombic structure The V2O5 submicronbelts exhibited a high initial discharge capacity of 346 mAh/g and stayed 240 mAh/g after 20 cycles at 01 C discharge rate in the potential region 18–40 VFinancial supports for this work are provided by 1 The National Natural Science Foundation of China grant 50474092 50874074 and 2 Shenzhen Key Laboratory of Functional Polymer Foundation FP20080003 The authors would also like give special thanks to Miss Xun Liang for assistance with proofreading of the text
