Fabrication of Novel Vanadium Dioxide Nanorods as Cathode Material for Rechargeable Lithium Batteries

Novel vanadium dioxide nanorods in diameter of 40–60 nm and in length up to 1–2 (mu)m were successfully fabricated via a surfactant-assisted hydrothermal method at 180 °C for 48 h. Electrochemical test results demonstrated that the nanorods showed an initial discharge specific capacity of 306 and 245 mAh/g in the fifteenth cycle.
