SYNTHESIS AND CHARACTERIZATION OF MG DOPED LIMNPO4 AS ALTRNATIVE CATHODE MATERIAL FOR LOTHIUM ION BATTERY

Abstract

The pristine LiMnPO4/C (LMP/C) and Mg-doped LiMn0.99Mg0.01PO4 (LMMP1) and LiMn0.97Mg0.03PO4 (LMMP3) samples have been synthesized for cathode material. In this study, the pristine and Mg doped LiMnPO4 cathode material is prepared using solid state route. Physio chemical characterization of the synthesized materials has been performed using X-ray diffraction (XRD), Scanning electron microscope (SEM) and Energy dispersive spectroscopy (EDS) to confirm proper phase formation, particle size and determination of composition respectively. The XRD patterns reveal the formation of the pure phase orthorhombic olivine structure of the pristine LiMnPO4/C (LMP/C) and Mg-doped LiMn0.99Mg0.01PO4 and LiMn0.97Mg0.03PO4 samples with Pnmb space group. SEM micrographs show the formation of dispersed, nanosized particle for the synthesized samples. Electrochemical performances for this pristine and Mg doped LiMnPO4 are further analyzed.
