摘要： A non-aqueous electrolyte secondary battery includes a positive electrode containing a positive-electrode active material, a negative electrode containing a negative-electrode active material, and a non-aqueous electrolyte, and is characterized in that the non-aqueous electrolyte contains 1.0 wt % or less of a compound represented by formula (1) and 2.0 wt % or less of a cyclic sulfate ester represented by formula (2), based on the total weight of the non-aqueous electrolyte. By using the non-aqueous electrolyte including a specified amount of the compound represented by formula (1) and a specified amount of the cyclic sulfate ester, when the battery is used at a low temperature after being stored at a high temperature, the increase of the internal resistance is inhibited.
