Abstract

Lithium vanadium phosphate (LVP, Li₃V₂(PO₄)₃) composites co-doped with cations and anions were synthesized via a rheological phase method reaction. The effects of Gd³⁺–Cl⁻ co-doping on the structure, morphology, and electrochemical performance of Li₃V₂(PO₄)₃ particles were then systematically investigated. This method of cation–anion co-doping did not change the structure of Li₃V₂(PO₄)₃. All co-doped samples exhibited better electrochemical performance than that of the undoped sample. The highest initial discharge capacity of co-doped samples was 169 mAh/g and a capacity of 72.8 mAh/g was obtained at 10C rate at 3.0–4.8 V. This synergistic mechanism of anion–cation co-doping is a promising approach to optimize the performance of Li₃V₂(PO₄)₃.
