Abstract

Abstract

In this paper, Sc³⁺ doped Li₃V₂(PO₄)₃/C cathode material was successfully prepared by carbothermal reduction method. The effects of Sc³⁺ doping amount on the structure, morphology and lithium storage properties of Li₃V₂(PO₄)₃ were systematically investigated. Although Sc³⁺ doping does not change the lattice type of Li₃V₂(PO₄)₃, it makes the lattice of Li₃V₂(PO₄)₃ expand and the unit cell volume increase, which is beneficial to electron transport and Li⁺ diffusion. In addition, Sc³⁺ doping makes irregular polygonal Li₃V₂(PO₄)₃ particles spheroidized and reduces the particle size. More importantly, the appropriate doping amount of Sc³⁺ can significantly enhance the electronic conductivity and Li⁺ diffusion coefficient of Li₃V₂(PO₄)₃ cathode material. Benefiting from the appropriate Sc³⁺ doping amount, carbon coating and porous structure, Li₃V_1.85Sc_0.15(PO₄)₃/C samples possess superior lithium storage properties. The initial discharge specific capacity is 84.8 mAh/g at 10 C rate, and the capacity retention rate is as high as 93.5 % after 100 cycles.
