ELECTROLYTE AND ELECTROCHEMICAL DEVICE |
| 摘要 |
The present invention provides an electrolyte solution that is capable of dealing with an increased voltage of an electrochemical device, as well as capable of improving the high-temperature storage characteristics and cycle characteristics of the electrochemical device, and an electrochemical device. The electrolyte solution includes a solvent containing a fluorinated saturated cyclic carbonate and a fluorinated acyclic carbonate; at least one sulfur-containing compound selected from the group consisting of compounds having a —SO2— bond, compounds having a —SO3— bond, and compounds having a —SO4— bond, and an electrolyte salt. The fluorinated acyclic carbonate has a fluorine content of 31.0 to 70.0 mass %. |
