V2ON thin film has been successfully fabricated by reactive dc sputtering method and annealing process and was investigated for its electrochemistry with lithium. The reversible discharge capacities of V2ON/Li cells cycled between 0.01 and 4.0 V were found in the range of 803–915 mAh g−1 during the first 50 cycles. By using ex situ scanning electron microscopy, transmission electron microscopy, selected-area electron diffraction and X-ray photoelectron spectroscopy measurements, the reversible transformation between nanocrystalline V2ON and well dispersed V, Li2O, Li3N nano-composites were revealed in the lithium electrochemical reaction. V2ON thin film exhibits high reversible capacity and good cycle performance with remarkable lower polarization than VN thin film.
► We have prepared V2ON thin film by reactive dc sputtering method and annealing process. ► We investigated for its electrochemistry with lithium. ► V2ON thin films exhibit a large reversible specific capacity of 830 mAh g−1 with much less polarization than VN thin films. ► The reversible transformation between nanocrystalline V2ON and well dispersed V, Li2O, Li3N nano-composites were revealed.
