Next, we examined the relationships between the activation energy and the prefactor across a diverse set of simulated polymers for three transport properties: 4(a) total ionic conduc- tivity, 4(b) Li diffusion coefficient, and 4(c) diffusion coefficient of constitutional repeat unit (CRU) (plot for TFSI diffusion coefficient provided in SI section 6). These plots capture the so-called Meyer-Neldel rule, and show entropy-enthalpy compensation for each relevant transport process. All of the points in Figure are colored by their respective ionic conductivity at the constant temperature shift (415 K). These relationships are calculated from simulations performed with DFT charges (the same analysis as with LPG charges can be seen in the SI section 6) and at the same ion concentration. We find that the natural logarithm of prefactors for transport and activation energies all exhibit a linear relationship. This points towards a general compensation effect of transport phenomena in conventional polymer electrolytes that lines up with previous work by Diederichsen et. al. The slope of the linear fit between Ea and lnA is called the Meyer-Neldel energy (∆ 0 ). The relative magnitude of ∆ 0 compared to the thermal energy (k B T ) at a given temperature T is thought to relate to whether a lower activation energy enhances the transport property at T or has the opposite effect. For all of the three transport properties plotted in Figure , ∆ 0 is significantly higher than k B T at 300 K (0.025 eV), indicating that a polymer with a lower activation energy would in general exhibit faster transport at 300 K. Specifically, ∆ 0 of ionic conductivity for our simulated polymers is 0.068 eV, which closely agrees with the 0.071 eV reported by Zhu et al. By calculating the activation energy required to achieve ionic conductivity of 1 mS/cm at 300 K for this group of polymers, we obtain a negative activation energy. This indicates that polymers within this Meyer-Neldel group inherently fail to reach such high ionic conductivity at 300 K, consistent with the findings of Zhu et al. These results suggest that rather than attempting incremental improvements within this group, efforts should focus on discovering fast-conducting polymers that fall outside this Meyer-Neldel relationship. In addition, the ∆ 0 of polymers is higher than that of most previously studied crystalline inorganic lithium superionic conductors, which typically range from 0.02 to 0.06 eV. As ∆ 0 corresponds to k B ∆H activation /∆S activation , characterizing the enthalpy-entropy compensation in the activation process of transport, a high ∆ 0 suggests either a high ∆H activation or a low ∆S activation . We hypothesize that the high ∆ 0 in polymers may result from a small ∆S activation stemming from the high degeneracy of lithium positions in the unactivated state compared to the crystallographically determined lithium positions in crystalline conductors.
