| titleOfInvention | Non-aqueous electrolyte lithium secondary battery |
| abstract | 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. |
