Abstract:
An object of the present invention is to provide a nonaqueous electrolytic solution capable of improving electrochemical characteristics in a broad temperature range, an energy storage device using it.A nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, which comprises at least one cyclic sulfonic acid ester compound represented by the following general formula (I), and an energy storage device. (wherein R1 and R2 may be the same or different, each representing a hydrogen atom, an alkyl group in which at least one hydrogen atom may be substituted with a halogen atom, orahalogenatom; L represents a divalent hydrocarbon group of an alkylene group in which at least one hydrogen atom is substituted with OR3, or a divalent hydrocarbon group of an alkylene group in which at least one methylene (CH2) is substituted with C(═O); R3 represents a formyl group, an alkylcarbonyl group, an alkenylcarbonyl group, an alkynylcarbonyl group, an arylcarbonyl group, an alkoxycarbonyl group, an alkenyloxycarbonyl group, an alkynyloxycarbonyl group, an aryloxycarbonyl group, a 2,2-dioxide-1,2-oxathiolan-4-yloxycarbonyl group, a 2,2-dioxide-1,2-oxathian-4-yloxycarbonyl group, an alkanesulfonyl group, an arylsulfonyl group, a dialkylphosphoryl group, an alkoxy(alkyl)phosphoryl group, a dialkoxyphosphoryl group, —S(O)—OR4, or —C(O)CH2P(O)(OR5)2; R4 represents an alkyl group, a 2,2-dioxide-1,2-oxathiolan-4-yl group, or a 2,2-dioxide-1,2-oxathian-4-yl group; R5 represents an alkyl group; further, in R3, at least one hydrogen atom may be substituted with a halogen atom, and L may be further substituted with any of an alkyl group, a haloalkyl group or a halogen atom).
