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： A lithium secondary battery has a cathode made of carbon material capable of occluding or emitting a lithium ion, a cathode made of lithium-contained oxide, and a non-aqueous electrolyte. The non-aqueous electrolyte includes a lithium salt containing LiPF 6 and LiBF 4 ; and a non-linear carbonate-based mixed organic solvent in which (a) a cyclic carbonate having ethylene carbonate or a mixture of ethylene carbonate and propylene carbonate and (b) a propionate-based ester such as ethyl propionate are mixed at a volume ratio (a:b) in the range from about 10:90 to about 70:30. This lithium secondary battery ensures excellent high-rate charging/discharging characteristics and improved life cycle and low-temperature discharging characteristics since it includes a predetermined mixed organic solvent not including a linear carbonate. Also, since gas generation is restrained at a high temperature, a battery set may be mounted in a more improved way.
