SYNTHESIS AND CHARACTERIZATION OF LITHIUM IRON PHOSPHATE-BASED CATHODE MATERIAL FOR LI-ION BATTERIES

Lithium iron phosphate (LiFeP04) is a potential cathode material for lithium-ion batteries due to its promising characteristics. In this study, LiFeP04 was synthesized via a modified rheological phase method. The material was characterized for its thermal, structural, and morphological properties. TG analysis revealed that formation of LFP may start at 300°C. XRD results reported an orthorhombic LiFeP04 structure with (311) as the dominant peak. The FTIR spectra matched that of a commercial LFP. SEM images showed agglomeration of particles. EDS detected the presence of Fe, P, 0, and C elements. Li was not detected due to limitation of equipment. Based on the results, the study was successful in synthesizing nanograined LFP
