The Distorted Oxygen Octahedron with Transition Elements in LiNi_0.75Co_0.15Mn_0.1O₂

Abstract:

LiNi_0.75Co_0.15Mn_0.1O₂ was prepared by solid state reaction and its crystal structure was studied by Rietveld Refinement. The result shows that the oxygen octahedron surrounding transition elements in LiNi_0.75Co_0.15Mn_0.1O₂ is distorted. The lengths of twelve edges of the octahedron are different. The lengths of twelve edges divided into two groups and their length is 2.7098Å and 2.8780Å respectively. The analysis shows that the change crystal fields due to transition metals and lithium ions results in the different length of octahedron edges in LiNi_0.75Co_0.15Mn_0.1O₂.
