(57) [Problem] To provide a method of manufacturing a non-aqueous electrolyte secondary battery in which a negative effect of an additive is unlikely to appear. This provides a method for producing a non-aqueous electrolyte secondary battery which has excellent discharge characteristics and life characteristics and generates less gas at high temperatures. SOLUTION: A negative electrode using any one of lithium metal, a lithium alloy, and a material capable of inserting and extracting lithium or a mixture thereof as a negative electrode active material, a positive electrode, a nonaqueous electrolytic solution comprising a nonaqueous solvent and an electrolyte, In the production of a non-aqueous electrolyte secondary battery containing at least a constituent element, a non-aqueous solution comprising at least a lithium salt of an electrolyte and a non-aqueous solvent containing a compound having a carbon-carbon multiple bond is used. A step of producing a water electrolyte secondary battery, a step of performing one or more charge / discharge operations on the battery, and a second non-aqueous solution containing an additive not included in the first non-aqueous solution after the charge / discharge operation And a step of adding a non-aqueous electrolyte secondary battery. |
