Synthesis of VO2 (B) nanorods for Li battery application
Ch.V. Subba Reddy,Edwin H. Walker Jr.,S.A. Wicker Sr.,Quinton L. Williams,Rajamohan R. Kalluru 한국물리학회 2009 Current Applied Physics Vol.9 No.6
Vanadium dioxide nanorods were synthesized through a hydrothermal reaction from V2O5 xerogel, poly (vinyl pyrrolidone) (PVP) and lithium perchlorate (LiClO4). The prepared samples were characterized by X-ray diffraction, infrared spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electrochemical discharge–charge cycling in lithium battery. SEM images reveal the nanorods to have dimensions on the order of 1–3 ㎛ in length and 10–50 nm in diameter. The measured initial discharge capacity of the lithium battery with a cathode made of VO2 (B) nanorods was 152 mA h/g.
