Effect of the Concentrations of the Reactants on Electrochemical Performance of Composite Cathode Material LiFePO₄/C

Abstract:

FePO₄·2H₂O nanoplates are synthesized by a hydrothermal method, using Fe (III) compound as the iron source and are lithiated to LiFePO₄/C by a simple rheological phase mathod. The structure, morphology and electrochemical properties of the FePO₄·2H₂O nanoplates and LiFePO₄/C composites synthesized by changing the concentration of the reactants were characterized in detail by X-ray (XRD), scanning electron microscope (SEM), high-resolution transmission electron microscope and electrochemical measurement. The LiFePO₄/C nanoparticles lithiated from the FePO₄·2H₂O nanoplates when there were about 10 mmol Fe³⁺ in 20 ml water solution demonstrates excellent cyclic performance.
