The magnitudes of Δ𝐸 A are summarized in Figure . The values are positive, indicating that the activation barrier increases for the heavier Li in all cases. Because Li10SnP2S12 exhibits two different transport processes (see top panel of Figure ) in the SAE NMR data, it contributes two SAE data points to the isotope effect analysis. Although the 6 Li6PS5Cl sample was found to have a secondary transport regime via BPP analysis (see bottom panel of Figure ), the corresponding transport regime in the 7 Li6PS5Cl sample could not be identified. Here, only comparable transport regimes were used to determine Δ𝐸 A .
