Title:
NONAQUEOUS ELECTROLYTIC SOLUTION AND ELECTRICITY STORAGE DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/016903
Kind Code:
A1
Abstract:
Provided are: a nonaqueous electrolytic solution that is capable of having improved electrochemical characteristics in a wide temperature range, that has an electrolyte salt dissolved in a nonaqueous solvent, and that is characterized by containing an (2-oxo-1,3-dioxolan-4-yl)oxy compound represented by general formula (I); an electricity storage device; and a novel (2-oxo-1,3-dioxolan-4-yl)oxy compound. (In the formula, R1 represents a hydrogen atom, a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, -OC(=O)-R4, -OS(=O)2-R5, or -OP(=O)(-R6)-R7. R2 and R3 each independently represent a hydrogen atom, a halogen atom, or an alkyl group, and n represents an integer of 1-3. R4 represents an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, or an alkoxycarbonyl group. R5 represents a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, or an alkoxy group. R6 and R7 each independently represent a halogen atom, an alkoxy group, or an aryloxy group. In the case where n is 1, L1 represents -C(=O)-R4, -S(=O)2-R5 or -P(=O)(-R6)-R7. In the case where n is 2, L1 represents -C(=O)C(=O)-, -S(=O)2-, or -P(=O)(-R6)-. In the case where n is 3, L1 represents -P(=O)(-)2.)
