Novel LiV(PO4)0.9F1.3 with ultrahigh rate capability and prolonged cycle life

Abstract

Novel triclinic LiV(PO4)0.9F1.3, characterized through its crystal lattice expansion, ultrafine primary particle size and uniform carbon coating, was designed and fabricated through regulating the PO4/F ratio. It exhibited excellent electrochemical performance, maintaining 105 mA h g−1 at 50C and 92.9% capacity retention after 500 cycles at 10C due to its superior structural stability, greater charge transfer properties, enhanced electronic conductivity and fast Li+ diffusion kinetics.
