摘要： To provide a non-aqueous electrolyte solution capable of improving cycle characteristics of a secondary battery, and a non-aqueous electrolyte secondary battery using the non-aqueous electrolyte solution.
A non-aqueous electrolyte solution according to an embodiment of the present technology includes an electrolyte salt and a non-aqueous solvent. The electrolyte salt contains an imide salt as a main electrolyte salt and at least one lithium oxalate borate selected from the group consisting of lithium bis(oxalate) borate (LiBOB), lithium fluoro(oxalate) borate (LiFOB), and lithium difluoro(oxalate) borate (LiDFOB). The non-aqueous solvent contains at least one halogenated carbonic acid ester selected from the group consisting of a halogenated chain carbonic acid ester and a halogenated cyclic carbonic acid ester.
