Effect of particle size on electrochemical performance of lithium iron phosphate materials

Abstract LiFePO 4 material has many virtues, such as rich raw materials, low price, excellent high temperature cycling performance and safety property. Lithium ion battery with positive electrode active is the most promising. However, compared other inherent disadvantage of poor electrical conductivity, it greatly limits its dynamic characteristics at temperature. In this paper, effect particle size /C on prepared via solid-state method systematically investigated. The structure morphology samples were characterized by X-ray diffraction (XRD) scanning electron microscope (SEM). electrochemical properties cathode materials studied Land 2001.
