Aim: Vanadium oxide nanofibers have been manufactured by the sol–gel electrospinning
method followed by the thermal treatment in air and argon.
Materials and Methods: The samples are characterized by optical, laser confocal and scanning electron
microscopy, energy-dispersive X-ray elemental analysis, X-ray diffraction, cyclic voltammetry,
and electrical conductivity measurements.
Results: The obtained VO2 nanofibers demonstrate the semiconductor-to-metal phase transition. Also,
the vanadium pentoxide nanofibers are examined as electrode materials for rechargeable Li-ion batteries.
