Abstract

Based on the method of in-situ polymerization synthesis, combining with two-step sintering process and two-step carbon coating, LiFePO₄/C composite cathode material had been prepared. The structure, microstructure and morphology were studied by X-ray diffraction (XRD), transmission electron microscopy (TEM) micrograph and scanning electron microscope (SEM) respectively. The electrochemical performances were researched by cyclic voltammetry (CV) and charge/discharge capacity. The results indicated that two-step carbon coating for LiFePO₄ was of more remarkable advantages compared with one-step carbon coating sample, such as more complete carbon coating and better electrochemical performance.
