摘要： A cylindrical lithium secondary battery includes an anode and a cathode, capable of occluding or emitting lithium ions; a non-aqueous electrolyte; and a CID (Current Interrupt Device) for intercepting electric current and lowering inner pressure when the inner pressure of the secondary battery is increased. The cylindrical lithium secondary battery may ensure the safety of the battery with respect to overcharging and also at the same time prevent the problem wherein the CID is activated too early, such that the battery stops its operation when the battery is used in a high-temperature environment.

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.
