Synthesis of Mg²⁺ and Al³⁺ Co-Doped Li₃V₂(PO₄)₃/C Powder

Abstract:

Mg²⁺2+,Al₃₊ Co-doped Li₃V₂(PO₄)₃/C powder was synthesized by sol-gel method under nitrogen. The crystal structure and micrograph ofLi₃V₂(PO₄)₃/C powder before and after doping was investigated by XRD, SEM and FT-IR. The effect of Mg2+/Al3+ Co-doping onLi₃V₂(PO₄)₃/C powder was discussed. The results indicated that Mg²⁺2+,Al₃₊ Co-doping did not change the crystal structure of Li₃V₂(PO₄)₃, but decreased the grain size of the as-synthesized powder. The FT-IR analysis indicated that weak Al-O bond was generated after doping.
