Abstract

Zr⁴⁺-doped hollow spherical Na₃V（₂ PO₄）₃ cathode material was prepared by spray drying method, and the influence of different Zr⁴⁺ doping levels（molar ratio of Zr⁴⁺ to Na_3-xV_2-xZr_x（PO₄）₃）on the material properties was investigated. Techniques such as X-ray diffraction（XRD）, scanning electron microscopy（SEM）, and in-situ XRD were used to analyze the effects of Zr⁴⁺ doping on the structure and electrochemical performance of the material. It can be observed that Zr⁴⁺ doping enhanced the structural stability of the material, effectively inhibiting structural collapse and volume expansion during cycling. When the Zr⁴⁺ doping level was 0.15, Na_2.85V_1.85Zr_0.15（PO₄）₃（NVZP-15）demonstrated a discharge specific capacity of 76.5 mA•h/g at 15.0 C, with a capacity retention of 80.6% after 800 cycles at 10.0 C.
