| Research Abstract |
Nanostructures for electrode materials can enhance the performance of rechargeable batteries. In this study, VO_2(A) nanowires with diameter of less than 50 nm and single-crystalline V_2O5 sheets with thicknesses of 50?100 nm were grown on silicon substrates and aluminum foils respectively by the physical vapor transport method. We investigated the performance of the nanometer-thick V2O5 sheets grown on an aluminum foil as a positive electrode material in lithium-ion batteries. Vanadium ions were reduced from 5+ to 4+ and partially to 3+ during the first discharge. A charge-discharge rate was also measured.
