摘要：

The samples of vanadium-doped LiMnPO4 have been synthesized by the solid-state reaction technique. To reduce the oxidation state of vanadium from V5+ to V4+, the samples have been additionally annealed under hydrogen atmosphere. The tetravalent state of vanadium was proved by analysis of V 2p X-ray photoelectron spectra. Raman spectroscopy, first-principle studies and magnetic measurements were used to determine the effect of V4+ on the Li-Mn phosphate properties. (C) 2014 Elsevier B.V. All rights reserved.
