Preparation and performance study of LiFePO4 and xLiFePO4·yLi3V2(PO4)3

Preparation and performance study of LiFePO4 and xLiFePO4·yLi3V2(PO4)3 LiFePO4/C and xLiFePO4·yLi3V2(PO4)3 composites were successfully prepared by the high-temperature carbon thermal reduction method using LiOH·H2O, Fe2O3, NH4H2PO4, five different compounds (citric acid, polyaniline, carboxymethyl cellulose, E-44 epoxy resin, and tartaric acid), and V2O5 as raw materials. X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), laser particle size analysis, specific surface area measurements, and electrochemical performance testing were used to study their structure, morphology, and electrochemical properties. The results showed that the LiFePO4/C materials exhibited significantly different polymerization degree, XRD spectra, specific surface area, and particle size distribution. Finally, 9LiFePO4·Li3V2(PO4)3 and LiFePO4/C coated using tartaric acid were shown to exhibit improved electrochemical performance. Research on Chemical Intermediates Springer Journals
