Polyacene (PAS) coated self-assembled porous micro-spherical LiFePO4 cathode material is successfully synthesized by spray drying method. The crystal structure of the sample is examined by X-ray diffraction (XRD). The micro-spherical morphology with porous structure is observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The electrochemical properties are investigated via galvanostatic charge-discharge experiments and electrochemical impedance spectroscopy (EIS) analysis. The material exhibits a high lithium ion diffusion coefficient about 10(-12) cm(2) S-...
