Facile Synthesis of Layered LiV3O8 Nanosheets and Their Electrochemical Performance as Cathode Materials for Li-Ion Batteries

Layered nanosheets of a LiV3O8 cathode material were successfully prepared via a modified solid-state synthesis. The morphological changes of the layered nanosheets of the LiV3O8 cathode, which resulted from preparation at different temperatures, strongly affected the electrochemical performance of this cathode material. The layered nanosheets of the LiV3O8 cathode prepared at 500 °C delivered the highest electrochemical performance with initial charge and discharge capacities of 212 and 175 mAh g−1, respectively, when cycled between 1.5 and 4.0 V versus Li/Li+. The particulate morphology of LiV3O8 showed widths in a range of 100-145 nm and lengths between 1.0 and 2.5 µm. The layered nanosheet structure contributed to the increased electrochemical performance of LiV3O8 as a cathode material for applications in high-energy lithium-ion batteries.
