Electrochemical Characterization of Metal Oxynitride Thin Film as New Lithium Storage Materials
Metal oxynitride (VxON, CrxON) thin film has been fabricated by reactive dc sputtering method and annealing process. Its electrochemical properties are investigated in a MxON/Li cell. The reversible specific capacities are around 830 mAh g-1 for VxON and 730 mAh g-1 for CrxON. By using selected-area electron diffraction and X-ray photoelectron spectroscopy measurements, New electrochemical reaction mechanism is uncovered, which should be responsible for its good electrochemical performance.
