Abstract

Nanocomposite materials, Na₃V₂(PO₄)₃/C and Na₃V₂(PO₄)₃/C/Ag, were synthesized by a modified Pechini method. Their properties were characterized with the use of the X-ray diffraction analysis, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, elemental analysis, Raman spectroscopy, impedance spectroscopy, and charge-discharge tests as cathode materials for sodium-ion batteries. The discharge capacity of Na₃V₂(PO₄)₃/C obtained at 600 °C was 116.1 and 75 mAh g⁻¹ at a current density of 11 (0.1 C) and 110 mA g⁻¹ (1 С) in the potential range of 2.7–3.8 V. The high capacity values for fast charge/discharge were achieved as a result of heat treatment by two steps and incorporation of appropriate amount of silver particles into Na₃V₂(PO₄)₃/C nanocomposite. The discharge capacities of thus obtained Na₃V₂(PO₄)₃/C with 0.2 wt% of Ag were 117.2, 112.5, and 83.5 mAh g⁻¹ at the current densities of 11, 110, and 880 mA g⁻¹. This experimental evidence reveals the great potential of NVP/C/Ag synthesized by the modified Pechini method as cathode materials for the production of sodium-ion batteries.
