V 2 O 3 nanoparticles covered by a 15 nm thick uniform carbon coating are prepared by reaction under autogenic pressure at elevated temperature of VO(OC 2 H 5 ) 3 at 700 °C. Further oxidation of this material produces carbon‐coated V 2 O 5 nanoparticles. Both materials reversibly insert Li (see figure) electrochemically in nonaqueous Li‐salt solutions.
