Disclosed is a nonaqueous electrolyte secondary battery including a negative electrode containing a carbon material, which is excellent in both life performance at low temperatures and low temperature discharge characteristics. In a non-aqueous electrolyte secondary battery comprising a positive electrode, a negative electrode containing a carbonaceous material, and a non-aqueous electrolyte, the non-aqueous electrolyte includes at least one of ethylene carbonate or propylene carbonate, and a chain carboxylic acid. A non-aqueous electrolyte secondary battery comprising an ester and a carbonyloxyester compound represented by the general formula (1). Here, R1 to R4 are hydrogen, an alkyl group, a halogen, a cycloalkyl group, or an alkenyl group, and n is 2 or 3. [Selection figure] None |
