摘要： A non-aqueous electrolyte solution for a lithium secondary battery includes a lithium salt and a carbonate organic solvent. The non-aqueous electrolyte solution further includes a fluoro group- containing sulphonate compound expressed by Chemical Formula 1. When the non-aqueous electrolyte solution is employed for a lithium secondary battery, low-temperature discharging characteristics and life cycle characteristics are greatly improved. Also, even though a battery is stored at a high temperature in a fully-charged state or a charging/discharging process is under progress, the decomposition reaction of a carbonate-based organic solvent is restrained, thereby solving the swelling problem and improving high-temperature life cycle characteristics.

摘要： The present invention relates to a lithium secondary battery comprising a negative pole for absorbing and discharging lithium ions, a positive pole made of a lithium-containing oxide, and a non-aqueous electrolytic solution. Said lithium-containing oxide contains a lithium nickel-based oxide, and said non-aqueous electrolytic solution contains both vinyl ethylene carbonate (VEC) and mono-nitrile. The lithium secondary battery of the present invention not only prevents the degradation of lifespan of charge/discharge cycles due to the use of lithium nickel-based oxide as a positive pole, but also suppresses the decomposition reaction of electrolytic solution even when the battery in a fully-charged state is kept at a high temperature or charged/discharged, thus preventing swelling and improving the lifespan characteristic of the battery even at a high temperature.
