非水系電解液及び非水系電解液二次電池

Japanese Patent JP7048674

B2

To provide a nonaqueous electrolyte whose dependency on a process during battery running-in operation is reduced and in which the variation range of battery output characteristics by the initial charge rate during the battery running-in operation can be reduced, a nonaqueous electrolyte secondary battery using the same, which is excellent in input/output characteristics or the like.SOLUTION: Disclosed is a nonaqueous electrolyte which contains: lithium hexafluorophosphate; lithium bisoxalate borate; and oxo fluorophosphate and further contains one or more kinds selected from a group consisting of (A) salt having F-S bond in a molecule, (B) salt having B-F bond in the molecule, and salt having P-F bond in the molecule (provided that the lithium hexafluorophosphate and the oxo fluorophosphate are excluded).SELECTED DRAWING: None
