  text: Mesoporous nanocrystalline TiO2 and TiO2–V2O5 microspheres were prepared by
    non-hydrolytic sol–gel from TiCl4, VOCl3, and iPr2O at 110 °C without any solvent
    or additives. The samples were characterized by elemental analysis, X-ray diffraction,
    Raman spectroscopy, scanning electron microscopy, nitrogen physisorption, and
    impedance measurements. At low vanadium loadings, only TiO2 anatase was detected,
    and V2O5 scherbinaite was also detected at high vanadium loadings. The texture
    of the samples depended on the V loading, but all the samples appeared built of
    primary nanoparticles (≈10–20 nm in size) that aggregate to form mesoporous micron-sized
    spheres. The lithium insertion properties of these materials were evaluated by
    galvanostatic measurements taken using coin-type cells, in view of their application
    as electrode for rechargeable Li-ion batteries. The mesoporous TiO2 microspheres
    showed good performances, with a specific reversible capacity of 145 and 128 mAh
    g−1 at C/2 and C, respectively (C = 335.6 mA g−1), good coulombic efficiency,
    and a moderate capacity fade (6 %) from the 2nd to the 20th cycle at C/20. Although
    the addition of V effectively increased the electronic conductivity of the powders,
    the specific reversible capacity and cycling performances of the TiO2–V2O5 samples
    were only minimally improved for a 5 at% V loading and were lower at higher V
    loading.
