Abstract
AbstractAmorphous iron vanadate (FeVO4) nanoparticle cathode materials are successfully synthesized through a facile, efficient, and high‐yielding ion exchange‐liquid precipitation method. The composition, structure, morphology, surface area, and electrochemical performances of the synthesized materials have been characterized by the Thermogravimetric‐Differential scanning calorimetry (TG‐DSC), X‐ray diffraction (XRD), field emission scanning electron microscopy (FESEM), X‐ray photon spectroscopy (XPS), Brunauer‐Emmet‐Teller (BET), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), respectively. The electrochemical performance results indicate that the amorphous FeVO4 delivers a specific capacity as high as 275 mAh g−1 at 0.1 C in a voltage range of 1.5–4.5 V. The excellent electrochemical performances can be ascribed to the pseudocapacitive behavior. The systematic kinetic analysis demonstrates that the pseudocapacitive charge storage allows the amorphous FVO cathode delivering the excellent high specific capacity.
