Layered lithium vanadium oxide LiV3O8 was synthesized by solid phase coordination method,and the reaction mechanism was studied by TG-DTA and XRD.The results show that LiV3O8 with a single phase can be obtained at 550 ℃ of heat treatment temperature for 24 h.The initial discharge capacity of the material reaches 180 mAh/g,showing better capacity storage performance.Using Coats-Redfern integral method and Anderson-Freeman differential method,the most probable mechanism of the synthesis process is random nucleation and subsequent growth,and the reaction equation and kinetics equation are derived.
