Description
In the current contribution, a systematic ex-situ neutron powder diffraction study on differently electrochemical delithiated NCA cathode materials is presented. A set of structural parameters was obtained by using full-profile Rietveld refinement. Lithium occupations have been found linearly reflecting the increasing state-of-charge. In contrast, the refined occupations of transition metals do not change on the state-of-charge, indicating the absence of antisite defects in the NCA material.
