Abstract

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.
