Mesoporous lithium vanadium oxide as a thin film electrode for lithium-ion batteries: comparison between direct synthesis of LiV2O5 and electrochemical lithium intercalation in V2O5

γ-LiV₂O₅ and α-V₂O₅ mesoporous thin films are prepared by a soft-templating route to compare the electrochemical performances of as-synthesized LiV₂O₅ with the in situ electrochemical intercalation of lithium ions in α-V₂O₅.
