چکیده انگلیسی
Composites of monoclinic Li3−xM′xV2−yM″2y(PO4)3 (M′ = K, M″ = Sc, Mg + Ti) with carbon were synthesized by solid-state reaction using oxalic acid or 6% H2/Ar gas mixture as reducing agents at sintering temperature of 850 °C. The samples were characterized by X-ray diffraction (XRD), voltammetry and electrochemical galvanostatic cycling. The capacity of Li3V2(PO4)3 synthesized using hydrogen as the reducing agent was 127 mA h g−1 and decreased to 120 mA h g−1 after 20 charge–discharge cycles. The substitution of lithium and vanadium for other ions did not result in the improvement of the electrochemical characteristics of the samples.
