AuTo+FL interatomic potential has the lowest average mean absolute error compared to DFT forces and energies across all geometry sets yet shows a monotonically increasing con- AuTo+O (yellow in Figure ) is the only studied IP that shows an overall decreasing lithium transference with increasing lithium salt concentration as expected from experiments, 1 while all nitrogen-coordinating IP (FL, AuTo+N, AuTo+FL) show increasing transference with increasing lithium salt concentration. Molinari et al. did not report their calculated transference numbers and therefore are not included in the comparison.
