The present invention relates to an electrolyte used in an electric double layer capacitor formed by a polarizable electrode using activated carbon and an electrolyte interface. Conventionally, tetraalkylammonium perchlorates such as tetraethylammonium perchlorate and tetrabutylammonium perchlorate, which are more stable against reduction than alkali metals, have been used as electrolytes in electrolytes for electric double layer capacitors. but,
This electrolyte is not easy to synthesize, and due to dehydration, there is a risk of explosion during drying, so sufficient care must be taken when handling it. However, the present invention provides an electrolyte solution using an electrolyte that is easy to synthesize and easy to handle. In the present invention, the electrolyte is a tetraalkylammonium trifluoromethanesulfonate such as tetraethylammonium trifluoromethanesulfonate or tetrabutylammonium trifluoromethanesulfonate, and the electrolyte is a solution obtained by dissolving this in an organic solvent alone or in a mixture. In the present invention, when tetraethylammonium trifluoromethanesulfonate is dissolved in the organic solvent dimethylformamide, the solubility at a liquid temperature of 25 [°C] is 2.60 [mol dm -3 ], and the electrical conductivity is 21.00.
It was [mcm -1 ]. Furthermore, when tetrabutylammonium trifluoromethanesulfonate is dissolved in dimethylformamide, the solubility at a melting temperature of 25 [°C] is 2.26 [mol dm -3 ], and the electrical conductivity is 10.97.
It was [mcm -1 ]. An example of an electrolytic solution obtained by dissolving the electrolyte of the present invention in a mixture of organic solvents is a formamide-based solvent such as N,N-dimethylformamide.
1.2-Add 1 to a solvent containing dimethoxyethane or tetrahydrofuran at a ratio of 10 to 50 [wt%].
An electrolytic solution is prepared by dissolving tetraethylammonium trifluoromethanesulfonate at a concentration of [mol/]. Next, electric double layer capacitors with a rating of 1.8 [V] and 10 [F] were manufactured, one using the conventional electrolyte (Conventional Example 1.2) and the other using the electrolyte according to the present invention (Example 1.2). ) with respect to capacity, internal resistance, and leakage current are shown in Table 1 in the form of good, fair, and bad.
