Abstract
A method of manufacturing a non-aqueous electrolyte secondary battery includes: (A) constructing an electrode group including a positive electrode and a negative electrode; (B) impregnating the electrode group with a first electrolyte solution; (C) charging the electrode group impregnated with the first electrolyte solution to a voltage of 4.3 V or more; and (E) manufacturing the non-aqueous electrolyte secondary battery by impregnating the electrode group with a second electrolyte solution after the charging. The first electrolyte solution includes a first solvent, a first lithium salt, and biphenyl. The first solvent does not include 1,2-dimethoxyethane. The second electrolyte solution includes a second solvent and a second lithium salt. The second solvent includes 1,2-dimethoxyethane.
