Abstract
An uncommon mixed-valence (+V/+IV) vanadium oxide with a layered-structure was prepared by a sol gel process, starting from a novel vanadium(IV) alkoxide, [{V(OPr i ) 3} 2 (μ-OPr i ) 2]. The obtained product was characterized by FT-IR, Raman spectroscopy, X-ray diffractometry, UV–Vis spectroscopy and EPR. The results indicate that it has a bariandite-like structure and a V 10O 24 · 9H 2O stoichiometry. Preliminary studies showed that this mixed-valence vanadium oxide has a good lithium intercalation capacity with make it a potential candidate to be used as cathode in lithium-based batteries.
