N2 - Li1+xV3O8 (LT-M form) was obtained by sol-gel method in CH3OH. This form, prepared 350 °C, possessed smaller grain size and better electrochemical performance than the HT form prepared by conventional high temperature synthesis. High discharge capacity (372 mAh·g-1: x = 4.0) and reversible discharge and charge cycle were attained. When heated at 200 °C, CH3OH molecules remained in the compound and crystallinity became lower by lithium insertion over x = 2.0. The lithium de-intercalation was irreversible.
