Abstract

The effects of calcination temperature on the physical and electrochemical performance of the Na₄MnV(PO₄)₃/C composites, which are prepared by a sol-gel method combined with the subsequent calcination in inert atmosphere, are reported in this work. The Na₄MnV(PO₄)₃/C composites are investigated by x-ray diffraction (XRD), N₂ adsorption/desorption isothermal, scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy and electrochemical measurements. The specific surface area, disorder of carbon, diffusion coefficients of Na⁺ (D_Na) and electrochemical performance of Na₄MnV(PO₄)₃/C composites are greatly influenced by the calcination temperature. The surface area and disorder of carbon of Na₄MnV(PO₄)₃/C substantially decrease with the calcination temperature increasing. While the D_Na and electrochemical performance of Na₄MnV(PO₄)₃/C composites improve with the calcination temperature from 650 to 750 °C and then degrade with the calcination temperatures from 750 to 850 °C. The results reveal that the optimal calcination temperature for the Na₄MnV(PO₄)₃/C composites is 750 °C and the corresponding Na₄MnV(PO₄)₃/C composite possesses the highest capacity and the best rate capability and cyclability amongst all these Na₄MnV(PO₄)₃/C composites in this work.
