The LiV3O8 nanoplates cathode materials was prepared by polyacrylamide-assisted freeze drying method. The annealing temperature affected the agrochemical properties of the LiV3O8 nanosheets cathode materials. The LiV3O8 nanoplates cathode materials were characterized by XRD, XPS, SEM, TEM, and galvanization charge/discharge profile measurement. The LiV3O8 fabricated at 550 °C (LVO550) showed the highest discharge capacity, best agrochemical performance, and high rate capability (after 100th, a reversible discharge capacity up to 223.8 mAh g−1). Benefiting from two dimensional nanoplates structure can provided a larger surface area, shorter lithium ion diffusion path, and maintain stable structure, the LiV3O8 nanoplates exhibited excellent rate capability, high reversible capacity and high temperature properties.
