Abstract:
1. A method for selecting an electrolytic solution for an electric double layer capacitor, comprising: A) a step of selecting a solute and a solvent; B) a step of assuming a model in which a cation and an anion constituting the solute form an association when the solute is dissolved in the solvent; C) a step of calculating the energy of the association when the association is in a stable state, to be considered a first value; D) a step of calculating the energy of the association when the association is reduced, to be considered a second value; E) a step of calculating the energy of the association when the association is oxidized, to be considered a third value; F) a step of finding a fourth value by subtracting the second value from the first value, and finding a fifth value by subtracting the first value from the third value; G) a step of finding a sixth value by subtracting the fourth value from the fifth value; and H) a step of comparing the sixth value with a target value of a potential window.
