Electrochemically Lithiated Vanadium Oxide, Li₂V₆O₁₃

Single crystals of V₆O₁₃ were grown by chemical vapour treatment; thereafter electrochemically lithiated. The title compound was the first phase formed during electrochemical lithiation at 2.65 V versus Li/Li⁺. The Li₂V₆O₁₃ structure can be described as layers of VO₆ octahedra stacked perpendicular to the c direction. Lithiation causes a 7.6% expansion along the c axis. The lithium ions occupy positions with a fivefold square pyrimidal oxygen coordination between the layers.
