Synthesis and Mechanism of LiV3O8 Material by Solid Phase Coordination
【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.
