Low-temperature Synthesis of LiV3O8 as Cathode Material for Rechargeable Lithium-ion Batteries

Abstract

Abstract: Layered-type compound of lithium vanadium oxide LiV₃O₈ was synthesized at about 450℃ by the sol-gel method with LiNO_₃and NH₃VO₃ as raw
materials. The influences of synthesis conditions on the first dischargeable specific capacities of the products were discussed by means of TG--DTG and XRD.
The experimental results indicate that the product LiV₃O₈ obtained under the optimum synthesis conditions has perfect layered-type structure and good
electrochemical property, its first discharge specific capacity is 350mAh·g^-1. It is an excellent cathode material for high-energy, long-life, rechargeable lithium-ion batteries.

Key words: lithium-ion batteries, lithium vanadium oxide, heat discomposition, specific capacity
