ELECTROLYTIC SOLUTION, ELECTROCHEMICAL DEVICE, LITHIUM-ION SECONDARY CELL, AND MODULE

Document Type and Number:

WIPO Patent Application WO/2018/123259

Kind Code:

A1

Abstract:

Provided is an electrolytic solution in which the residual volume does not readily decrease and the resistance increase rate does not readily change, even when the electrolyte solution is stored at high temperature. An electrolytic solution characterized in containing a fluorinated carbonate, a specific additive, and a compound (1) represented by general formula (1): R11CFX11(CH2)n11COOR12 (where R11 is H, F, a C1-C3 non-fluorinated alkyl group, or a C1-C3 fluorinated alkyl group; X11 is H or F; R12 is a C1-C3 non-fluorinated alkyl group or a C1-C3 fluorinated alkyl group; and n11 is an integer from 0 to 3).
