Pauling electronegativities of the species involved. The study reveals that within a specific class of materials, the migration barriers can be related to this descriptor through linear scaling relations, as shown in Figure . These relations can be established by varying either the cation chemistry of the charge carriers or the anion chemistry of the host lattice. The existence of these scaling relations suggests that a purely ionic perspective is insufficient for understanding all the factors that influence the ion mobility in solid materials. The discovery of these scaling relations has significant implications as it shows the potential to accelerate the process of finding materials with desired ion mobility properties such as oxide spinels. By utilizing this approach, researchers can more efficiently explore and identify materials that exhibit enhanced ion mobility, thus contributing to the development of improved electrochemical devices, including batteries and solid electrolytes.
