Abstract

Solid solutions of Mn1 − xMo2xV2(1 − x)O6 (x = 0, 0.4) were synthesized by classical solid-state reaction from Mn2O3, V2O5, and MoO3 as starting materials. X-Ray diffraction (XRD) analysis showed that the prepared samples belong to the monoclinic brannerite-type structure with space group C2/m. L-Edge X-ray absorption near-edge structure (XANES) data of Mn, V and Mo in Mn1 − xMo2xV2(1 − x)O6 (x = 0, 0.4) revealed that the valences of the corresponding metals are almost +2, +5 and +6, respectively. The electrochemical properties were considerably affected by Mo doping. The brannerite Mn0.6Mo0.8V1.2O6, which is an intermediate composition of Mn1 − xMo2xV2(1 − x)O6, exhibited a higher charge–discharge capacity of 1000 Ah kg−1 and enhanced rate capabilities compared with the parent MnV2O6.
