Review of Li 3 VO 4 anode materials for energy storage

Li3VO4 anode has advantages of high energy density, long cycle life, safe working voltage, low cost, and simple synthesis process. It is considered to be a promising intercalation anode material for lithium ion batteries (LIBs). However, its practical application is limited for poor electronic conductivity and low initial coulombic efficiency (ICE). At present, nanocrystallization, surface coating, material combination and lattice doping are adopted to improve the electrochemical performance, including ICE, rate capability, cycling stability, etc. This review systematically summarizes the progress and challenges of Li3VO4 anode for energy storage, and provides some guidance for its future study.
