Comparing the convergence of the log-log slope of mean squared displacement against timewindow (power law constant), which must be 1 for particles to be in the diffusive regime, we see that at neither experimental nor shifted-temperature simulations this metric reaches a mean value of 1 regardless of the simulation time. It is important to note that for polymers where the Li motion is dominated by the segmental motion of the polymer chain (e.g. PEO) the convergence of the Li diffusion will be more dependent on the convergence of polymer segment diffusion, which is slower. At the same time, both the shifted and unshifted loglog slopes reach a plateau after 10 ns and slowly increase over time, with the simulations at shifted temperature being close to convergence. Similarly, we compare the convergence of self-diffusion coefficients (for Li and TFSI) as well as the convergence of the transference number. We do this by comparing the value computed from a subset of the simulation to the entire simulation (300 ns). Similar to the convergence of power law constant, we find that the shifted-temperature simulations converge faster for both of these metrics (Figure (c)).
