V2O3 nanoparticles covered by a 15 nm thick uniform carbon coating are prepared by reaction under autogenic pressure at elevated temperature of VO(OC2H5)3 at 700 °C. Further oxidation of this material produces carbon-coated V2O5 nanoparticles. Both materials reversibly insert Li (see figure) electrochemically in nonaqueous Li-salt solutions.
