Electrochemical Properties of Chemically Etched-NbO₂ as a Negative Electrode Material for Lithium Ion Batteries

Article Preview

Abstract:

The electrochemical properties niobium dioxide (NbO₂) was investigated as a negative electrode material for lithium ion batteries. The NbO₂ electrode showed a large irreversible capacity and small discharge capacity. The results of X-ray photoelectron spectroscopy indicate that the poor electrode performance of NbO₂ may be caused by niobium pentoxide (Nb₂O₅) formed on the surface of active material. The Nb₂O₅ could be removed by chemical etching to some extent, thus improving the electrode performance.
