Still, the determination of the energy minimum path is computationally rather demanding as it requires multiple evaluations of the energy of the migrating ion at several points be-2 tween the initial and final state in a parallel fashion until the minimum energy path has been identified. Alternatively, activation barriers can be obtained through molecular dynamics (MD) simulations at different temperatures, assuming that the overall temperature dependence is determined solely by the Boltzmann factor. However, it is worth noting that these simulations are often even more numerically demanding.
