Lithiation characteristics of α-CuV2O6 and other nCuO · V2O5 oxides
Abstract Lithiation characteristics of a complex oxide containing V(V) and Cu(II), α-CuV 2 O 6 , were investigated. Lithiation was carried out chemically using an n - BuLi / hexane solution. The valence states of copper and vanadium and the structural changes upon lithiation were analyzed using ESR, XRD and OCV measurements. It was revealed that reduction processes occurred consecutively with an increasing extent of lithiation, x = Li (Cu + 2V) and Cu(II) component was reduced to Cu(I) preferentially over V(V). The single phases exist at 0 x x x x nCuO · V 2 O 5 were compared by the galvanostatic intermittent titration technique.
