The electrochemical insertion of lithium ions in V2O5 produces various crystal structures depending on lithium concentration. Compositions with lithium content in the range of 1 ≤ x ≤ 1.8 take orthorhombic γ-LixV2O5 form. γ-LixV2O5 is capable to accommodate more than one lithium ion per formula unit and therefore interesting to be used as a cathode of lithium-ion battery. Here are
presented electrochemical performances of γ-LiV2O5 obtained through solid-state reaction. Before galvanostatic cycling the as-synthesized powder is characterized by X-ray powder diffraction, field emission scanning electron microscopy, and FTIR spectroscopy. The crystal structure of the powder is refined in the orthorhombic Pbnm space group. During galvanostatic cycling in a large potential window capacity decrease is observed. In order to reveal the origin of capacity decay the bond valence analysis was performed. It provided a model of lithium diffusion network for the γ-LixV2O5 phase, as well as for the e...nd members obtained at low and high voltages.
