Abstract

In this paper, Lithium iron phosphate materials coated with conductive polymer were prepared by high temperature solid phase method. For the sake of investigating the effect of conductive polymer coating on Lithium iron phosphate materials, Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), charge and discharge test, rate performance and electrochemical impedance were used to analyze the microstructure and electrochemical of the materials. The results displayed that Polypyrrole coating did not change the structure of lithium ferric manganese phosphate, and the HRTEM image can clearly showed that the polypyrrole uniformly coated on the surface of LiFe_0.5Mn_0.5PO₄ nanorods. And the modified materials showed higher discharge capacity than the bare material.
