Sodium ion batteries have a tremendous attraction recently as the best alternative to lithium ion batteries forpotential application in large scale electrical energy storage devices. Among the various classes of iron phosphate cathodesused in sodium ion batteries, NaFePO4 is one of the most attractive host materials for advanced sodium ion batteries owingto its structural stability. A new polyanionic NaFePO4nanocomposite has been synthesized via sol–gel route. The structuralevolution of the material was characterized by powder X-ray diffraction.The intensity of the peaks of NaFePO4 is muchstronger, which implies that the structure of the material is more orderly. The presence of certain functional groups wasidentified using Fourier transform infra–red spectroscopy. The FT-IR spectrum of sodium ion phosphate mainly consists ofvibrational peaks of PO43-groups. The local structure of NaFePO4 was investigated by laser Raman spectroscopy. TheRaman shift appeared in the range of 400–700cm-1that belongs to Fe-O vibrations. The surface morphology of the samplewas analyzed using scanning electron microscope with various magnifications. The particle size was found to be in the range100–200nm. These results explored that the as-prepared NaFePO4nanocomposites may be a promising candidate as cathodematerial for sodium ion batteries.
