Abstract
A non-aqueous electrolyte solution for a lithium ion secondary battery includes a lithium salt and an organic solvent. The organic solvent includes a carbonate compound, a linear ester compound and a linear ester decomposition inhibitor. This non-aqueous electrolyte solution restrains swelling while improving low temperature charging/discharging characteristics of the secondary battery in comparison to a conventional electrolyte since it contains the linear ester compound and the linear ester decomposition inhibitor. The non-aqueous electrolyte solution may be used in making a lithium ion secondary battery.
