Description
Summary:The MoxV3−xO7/MWNTs nanocomposites were fabricated via a hydrothermal reaction followed by self-assembling process. The nanocomposites were characterized in terms of surface morphology and structure by FESEM, TEM, XRD and XPS analysis, respectively. The electrochemical behaviors of the nanocomposites were investigated by galvanostatic charge-discharge test and cyclic voltammetry. The results showed that MoxV3−xO7/MWNTs nanocomposites had great cycleability as well as capacity characteristics, which was 277.4 mAh/g in the first discharge process and remained 207.9 mAh/g after fiftieth discharge cycle. In the rapid charge-discharge test, the capacity rate still remained 88.6 % after twentieth cycles at 1.2 C discharge.
