Organic electrolytic solution and lithium secondary battery adopting the same |
摘要 |
An organic electrolytic solution and a lithium secondary battery employing the same are provided. The organic electrolytic solution contains an organic solvent and a lithium salt and the organic solvent includes 20 to 60% by volume of ethylene carbonate, 20 to 70% by volume of dialkyl carbonate and 5 to 30% by volume of a fluorinated toluene compound. The organic electrolytic solution has improved high-temperature exposure characteristic by virtue of the use of a fluorinated toluene compound having a high boiling point in combination with mixed solvents of ethylene carbonate and dialkyl carbonate. The lithium secondary battery employing the organic electrolytic solution is excellent in the high-temperature exposure characteristic, while maintaining good discharge capacity and lifetime characteristics.
