Figure 3

Evaluation of the activation energy and its relationship with calculated desolvation energy. Nyquist plots of the three-electrode cell (a) and Al-Al symmetric cell (b) with the electrolyte of Al(OTF)3-H2O, inset: equivalent circuit used for fitting the Nyquist plots; temperature dependence of charge-transfer resistances at cathode by using three electrode cell (c) and anode by using symmetric cell (d); the activation energies were obtained from the slope. (e) Relationship between computationally calculated desolvation energies and the experimentally evaluated charge transfer activation energy.
