4DescriptionAbstract LiNi1/3Co1/3Mn1/3O2 was synthesized by solid state reaction method and the effect of calcination temperature on characteristics of LiNi1/3Co1/3Mn1/3O2 cathode was investigated. Thermal analysis reveals the temperature dependence of the materials properties. The phase composition, micro-morphology, elemental analysis and Wyckoff sites of the products were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectra (EDS) and Fourier transform infrared (FTIR) respectively. The results of XRD pattern possessed the α-NaFeO2 structure of the hexagonal system (space group R3 ‾m). The morphological features of the powders were characterized by scanning electron microscopy (SEM). The EDS spectra confirm the presence of Ni, Co, Mn and O in the compound. The FT-IR spectroscopic data reveals that the structure of the oxide lattice constituted by LiO6, NiO6, CoO6 and MnO6 octahedral. The variation of the ac conductivity, dielectric constant and electric modulus as function of frequency and temperature was determined to study the electrical properties of the synthesized sample. Electron spin resonance (ESR) was carried out to study the magnetic properties as well. From this study, we conclude that the layered LiNi1/3Co1/3Mn1/3O2 material prepared by solid-state reaction method at 900 ?C for 18 h is promising next-generation cathode material for lithium ion batteries.
