Crystalline MnV2O6 with brannerite structure was synthesized by a classical solid-state reaction and its electrochemical reaction mechanism as an anode for a Li secondary battery was investigated. The reversible capacity of the MnV2O6 anode during the first cycle was about 670 A h kg(-1). An irreversible structural transformation into an amorphous phase via a rock-salt type structure was observed during the first Li insertion/removal reaction by X-ray diffraction (XRD) analysis. The charge compensation and the change in the local environmental structure during the Li insertion/removal were confirmed by X-ray absorption fine structure (XAFS) of Mn and V.
