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

In this work, sphere-like, star-like and rod-like InVO4 microstructures were synthesized through a facile hydrothermal process without using any organic additives or templates, this gives a new path for convenient synthesis of InVO4 microstructures with different morphologies. The possible formation mechanisms for the InVO4 microstructures with different shapes are elucidated. Furthermore, the electrochemical intercalation performances with Li+ of the as-prepared InVO4 samples are investigated. The reversible discharge capacities of sphere-like, star-like and rod-like InVO4 microstructures 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 InVO4 products had effect on their electrochemical properties.
