Biomimetic synthesis and characterization of the positive electrode material LiFePO4

The biosurfactant is used as the template to synthesize lithium iron phosphate (LiFePO4) precursor with the co-precipitation method and the microwave sintering method is used to prepare positive electrode material LiFePO4 for the lithium ion battery. By using the Brunauer-Emmett-Teller (BET) surface areas, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and conductometer, the authors explored the influence of the microwave power on the structure and performance of the materials. The results the authors got have proved that good crystal and high conductivity values can be obtained from the LiFePO4 powders which are processed 10 min under the microwave power of 300 W.
