The value of the solvation energy for the cations decreases exponentially with an increase in the ε HOMO or ε LUMO values (Figure ). The lowest solvation values are observed for Li + , which is followed by the other alkali metals, with the maximum values obtained for the organic cations. The G solv (ε HOMO-1 ) dependence for the anions has a characteristic volcano shape with a maximum at ε HOMO-1 = -0.42 a.u. (Figure G). The left part of the dependence is formed by the halides, the right partby the other ions. A significant deviation from the trend is observed for OH -, the energy value of which is significantly underestimated. TFSI -, the solvation energy of which is slightly overestimated, is out of the trend. The lowest values of G solv are observed for F -, OH -and the highest values for TFSI -.
