Titles:
NON-AQUEOUS ELECTROLYTE SOLUTION AND ELECTRICITY STORAGE DEVICE IN WHICH SAME IS USED
非水電解液及びそれを用いた蓄電デバイス
Abstracts:
The present invention is: a non-aqueous electrolyte solution for an electricity storage device in which an electrolytic salt is dissolved in a non-aqueous solvent, wherein the non-aqueous electrolyte solution is characterized by containing 0.1-4% by mass of a compound represented by general formula (I), and containing 0.1-30% by mass of at least one selected from the group consisting of fluorine-containing cyclic carbonates and unsaturated-bond-containing cyclic carbonates as an additive; and an electricity storage device in which it is possible to improve continuous charging characteristics in a high-temperature, high-voltage environment. (In the formula, R1 represents a C1-7 alkyl group or a C3-6 cycloalkyl group; R2 through R6 each independently represent a hydrogen atom, a C1-4 alkyl group, or a -CH2OC(=O)OR7 group; R7 represents a C1-4 alkyl group; and n is 0 or 1.)
