ABSTRACT

The lithiated transition metal oxide LiVMoO₆ has been synthesized by solid state reaction. This is the first report of this compound to be studied as an anode material for use in secondary batteries. The synthesized LiVMoO₆ powder has been studied by means of X-ray diffraction (XRD) and X-ray absorption near edge structure (XANES) spectroscopy. The electrochemical characteristics of the prepared electrodes assembled in coin cells were also investigated in terms of half-cell performance. It is observed that the cell exhibits three stages of discharge plateaus. The total discharge capacity, averaged over several test runs, is about 1250 mAh/g. This value is much higher than the capacities exhibited by many kinds of anode materials.
