Shape-Controllable Synthesis and Electrochemical Performance of InVO4 Microstructures as Electrode Materials for Li-Ion Battery

Abstract

In this work, sphere-like, star-like and rod-like InVO4microstructures were synthesized through a facile hydrothermal process without using any organic additives or templates, this gives a new path for convenient synthesis of InVO4microstructures with different morphologies. The possible formation mechanisms for the InVO4microstructures with different shapes are elucidated. Furthermore, the electrochemical intercalation performances with Li+of the as-prepared InVO4samples are investigated. The reversible discharge capacities of sphere-like, star-like and rod-like InVO4microstructures were 484.2 mAh g-1, 551.0 mAh g-1, and 603.3 mAh g-1, respectively. The results indicated that the morphologies of InVO4products had effect on their electrochemical properties.
