Abstract
Provided is a method for producing a non-aqueous electrolyte secondary battery with which resistance increase is inhibited during high-temperature storage while good battery properties are retained. The production method of this invention comprises a step of obtaining a positive electrode, a negative electrode and a non-aqueous electrolyte; and a step of placing the positive electrode, the negative electrode and the non-aqueous electrolyte in a battery case. Herein, the non-aqueous electrolyte comprises a fluorine atom-containing supporting salt and a benzothiophene oxide.
