Abstract

Li, Fe and V were reclaimed from spent LiFePO₄ and Li₃V₂(PO₄)₃ LIBs (Lithium Ion Batteries) due to their similar characteristics and preparation methods and then xLiFePO₄-yLi₃V₂(PO₄)₃ material was prepared. The spent battery material was heat treated at 600 ^oC for 1 h in air to remove the PVDF binder, and then the active materials and aluminum foil collector were separated effectively. The xLiFePO₄-yLi₃V₂(PO₄)₃ (x:y=5:1, 7:1, 9:1) was prepared through adjusting the mole ratio of Li, Fe, V and P, ball milling and calcining. The morphology, structure and electrochemical properties of the composite material were characterized. The results show that the prepared composite material has the electrochemical properties of both LiFePO₄ and Li₃V₂(PO₄)₃ simultaneously, which can significantly improve the rate capability of LiFePO₄.
