摘要
Vanadium oxide Li3VO4 has attracted much attention as anode material for Li-ion batteries in recent years since it has a low and safe redox potential (vs. Li metal), high specific capacity and its cost is low. However, the poor electronic conductivity and initial low coulombic efficiency limit its practical application. In this mini-review, the state-of-the-art results associated with Li3VO4 are summarized including structure, lithium insertion mechanism, preparation, modification, and electrochemical properties. Finally, the challenges and prospects are also discussed.
