| Summary: | © 2017, Pleiades Publishing, Ltd. One dimensional WO 3 nanowires with high aspect ratio of > 200 were synthesized by hydrothermal method. The effects of reaction temperature and time on phase and morphologies were studied and discussed. In this research, a suitable hydrothermal condition is at 200°C for 48 h. XRD, SEM, and TEM results show that the product is hexagonal WO 3 phase with diameter of 25 nm and several ten micrometers long with growth in the c direction. The electrochemical properties were tested for rechargeable lithium batteries. The WO 3 NWs electrode exhibits a stability trend over the 30 cycle testing. Some long-term activation process is attributed to the WO 3 NWs electrode during charge/discharge reaction. |
