发明名称 | Non-aqueous electrolyte solution for electric double-layer capacitor | ||
摘要 | A non-aqueous electrolyte solution for an electric double-layer capacitor includes a non-aqueous solvent in which electrolyte salt is dissolved. The non-aqueous electrolyte solution is characterized in that the non-aqueous solvent is a mixed solvent of chained sulfone and cyclic lactone compound. The non-aqueous electrolyte solution can suppress increase in the resistance value of the electric storage element even in a low-temperature environment below 0° C. and can also be used in a normal-temperature environment. | ||

主权项 | 1. A non-aqueous electrolyte solution for a double-layer capacitor which is a non-aqueous electrolyte solution constituted by a non-aqueous solvent in which electrolyte salt is dissolved, wherein the non-aqueous solvent is a mixed solvent of chained sulfone and cyclic lactone compound, wherein a mass ratio of the chained sulfone and the cyclic lactone compound is in a range of 6:4 to 1:9, the chained sulfone is selected from the group consisting of ethylisopropyl sulfone, ethylmethyl sulfone, isopropylmethyl sulfone, ethylisobutyl sulfone, isobutylisopropyl sulfone, isobutyl sec-butylsulfone, butylisobutyl sulfone, and combinations thereof, and the cyclic lactone compound is selected from the group consisting of γ-butyrolactone, γ-valerolactone, δ-valerolactone, and combinations thereof. | ||
