Structural Analysis of LiNi_0.7Mn_0.3O₂ as Cathode Material for Rechargeable Lithium-Ion Batteries

Abstract:

The layered rock salt LiNi_0.7Mn_0.3O₂ was prepared by conventional solid-state synthesis route. The prepared samples were analysed using X-ray diffraction (XRD) to determine purity of samples. Then, structural analysis and crystallographic properties of samples were analysed using Rietveld refinement. Rietveld refinement results indicated that the amount of cation disorder in the layered rock salt structure highly influenced by temperature and synthesis conditions. The most optimum temperature to obtain the highest degree of cation ordering is between 850^oC and 900^oC in air.
