LixV2O5 was synthesized via a sol-gel synthesis approach in accordance with earlier reports by Clites et al. 2.33 g of LiCl (ThermoFisher) was added to 15 mL deionized water in a glass beaker with constant stirring. Subsequently, 15 mL of 30 wt.% H2O2 aqueous solution (Sigma Aldrich) was added. 0.5 g α-V2O5 was then slowly added to the solution under vigorous stirring.
