Abstract

At present three major layered structured oxides (LiCoO2, LiNiO2, and LiMnO2) are used for cathode materials. In the present study we synthesis LiNi0.92Mg0.08O2 and LiNi0.92Co0.06 Mg0.02O2 cathode materials in solid state reaction method at high temperature. The crystalline powders are characterized for their phase identification using x-ray diffraction analysis (XRD). All two synthesized samples possessed the α-NaFeO2 structure of the rhombohedral system (space group, R3¯m) with no evidence of any impurities. The morphological features of the powders are characterized by field effect scanning electron microscopy (FESEM). The Fourier Transform infrared (FT-IR) spectroscopic data reveals the structure of the oxide lattice constituted by LiO6 and NiO6 octahedra.
