Chemical Structure from Scientific Research

Crystal structure of ordered spinel (Left) and PDS (Right, where Td-8a, Td-8b, Oh-16c, and Oh-16d are highlighted as colored polyhedra in ordered spinel. The black, yellow, and silver spheres represent the occupying Li, M, and F/O atoms, respectively. The enlarged Td-8a site illustrates Li migration through a 0-TM channel in the spinel structure. In PDS, 16c sites can be occupied by Li, TM, and vacancies (V), and 16d sites can be occupied by both Li and TM, representing the 16c/16d disorder in PDS.
