A novel anode material LiVMoO₆ for rechargeable lithium-ion batteries

Mixed transition metal oxide LiVMoO₆ was synthesized by the solid-state reaction method and was exploited as an anode material for use in rechargeable lithium-ion batteries. The electrochemical characteristics of the prepared electrodes assembled in coin cells were investigated in terms of half-cell performance. It was observed that the cell exhibits three discharge plateaus. The total discharge capacity, averaged over several test runs, is about 1250 mAh/g. The mechanism of electrochemical reaction of LiVMoO ₆ with Li was studied in situ by the synchrotron X-ray diffraction method. It was found that LiVMoO₆ undergoes irreversible decomposition during the first discharge.
