Title:
NONAQUEOUS ELECTROLYTIC SOLUTION INCLUDING ESTER HAVING 3,3,3-TRIFLUOROPROPIONATE GROUP AND NONAQUEOUS ELECTROLYTE BATTERY USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/006315
Kind Code:
A1
Abstract:
Provided are a secondary battery nonaqueous electrolytic solution that has excellent oxidation resistance, that suppresses a reaction between the nonaqueous electrolytic solution and an electrode, that suppresses decomposition even under high-voltage conditions, and that can suppress capacity deterioration of the secondary battery and gas generation therein, as well as a nonaqueous electrolyte secondary battery using the nonaqueous electrolytic solution. Provided is a secondary battery nonaqueous electrolytic solution characterized by including: a nonaqueous solvent including an ester having a 3,3,3-trifluoropropionate group represented by formula 1, a fluorinated cyclic carbonate that is a 4-fluoroethylene carbonate (FEC) or a derivative thereof, and at least one selected from among a cyclic carbonate, a chain carbonate, and a fluorinated chain carboxylic acid ester; and a lithium salt serving as an electrolyte.
