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