| Abstract: | The application of the lithium iron phosphate cathode materials was described.Its structural characteristics were analyzed.The lithium iron phosphate was synthesized by carbothermal reduction method using ferric iron phosphate and lithium carbonate.The crystal structure and morphology of the LiFePO4/C were characterized by X-ray diffraction (XRD),energy dispersive spectrometer (EDS),scanning electron microscopy (SEM) and transmission electron microscope (TEM).The results show that the properties of the LiFePO4/C are enhanced. |
