Document Type and Number:
WIPO Patent Application WO/2021/125301
Kind Code:
A1
Abstract:
Provided are: a non-aqueous electrolyte solution that can suppress the room-temperature and/or low-temperature discharge resistance growth of an energy device; and an energy device that includes the non-aqueous electrolyte solution. A non-aqueous electrolyte solution for an energy device that comprises a positive electrode and a negative electrode. The non-aqueous electrolyte solution is characterized by containing an electrolyte, a non-aqueous solvent, a linear sulfonic acid ester, and at least one compound selected from the group that consists of fluorosulfonates, monofluorophosphates, difluorophosphates, imide salts, and oxalates, the mass ratio of the amount of the linear sulfonic acid ester to the amount of the at least one compound selected from the group that consists of fluorosulfonates, monofluorophosphates, difluorophosphates, imide salts, and oxalates being within a specific range.
