英文摘要: Doping modification of electrode materials is a sought-after strategy to improve their electrochemical performance in the secondary batteries field. Herein, polyanion (BO3)3−-doped Li3V2(PO4)3 cathode materials were successfully synthesized via a wet coordination method. The effects of (BO3)3− doping content on crystal structure, morphology and electrochemical performance were explored by X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). All the as-prepared samples have the same monoclinic structure; among them, Li3V2(PO4)2.75(BO3)0.15 sample has...
