    摘要: 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.

    摘要: Disclosed are a non-aqueous electrolyte solution for a lithium secondary battery and a lithium secondary battery comprising the same. The non-aqueous electrolyte solution for a lithium secondary battery comprises a silicon-based compound represented by a specific chemical formula and having both a hydroxyl group and a hydrocarbon group having a carbon-carbon double bond. When it is applied to a lithium secondary battery, the non-aqueous electrolyte solution improves deterioration of cycle life characteristics occurring after repeated charge/discharge cycles and prevents swelling phenomena by suppressing a decomposition reaction of an electrolyte solution even when a battery in a fully charged state is stored at high temperature or is charged/discharged, thereby enhancing the life characteristics at high temperature.

    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 LiPF6 and LiBF4; 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.
