where kb is Boltzmann's constant, T the temperature in K and Ea, A->B the activation energy of a generalized jump event from site A to site B. We would like to highlight that a site-independent, isotropic attempt frequency of 1.08 •10 13 Hz is assumed. Ea, jump calculated with equation 1 can thus not be interpreted as the actual energy-barrier for diffusion between two sites. Ea, jump should rather be interpreted as a metric for the affinity for jumps between two sites. The affinity for jumps between two sites is also represented by the jump frequency vA->B but we favor the use of Ea, jump over vA->B, because vA->B is temperature dependent. The temperature dependence of vA->B is moderated by the temperature term T in equation 1, making Ea, jump a temperature-independent metric for the affinity for jumps between two sites. Figure shows the activation energy Ea, jump for individual jump events in LNCl. The Ea, jump values in LNCl span a wide range from 0.2 to 0.5 eV and it becomes apparent that jumps originating from Cl2N2 and Cl3N1 sites towards Cl4 sites show particularly high Ea, jump values (>0.4 eV). Figure shows the energy differences between the Li sites. This energy difference between Li sites was obtained by displacing a Li ion in a site A to a vacant site B. We then interpreted the energy difference between the two supercells as the energy difference between sites A and B. It becomes apparent that Cl4 sites are >100 meV higher in energy than all other sites. The large Ea,jump values for Cl2N2->Cl4 and Cl3N1->Cl4 jumps thus likely originate from the large site-energy differences between Cl2N2/Cl3N1 and Cl4 sites.
