description Disclosed are an electrolytic solution for lithium secondary batteries capable of improving lifespan characteristics of a lithium secondary battery under a high voltage condition and a lithium secondary battery including the same. The electrolytic solution includes a lithium salt, a solvent, and a functional additive, and the functional additive includes a high-voltage additive including a first high-voltage additive, perfluoro-15-crown-5-ether, represented by [Formula 1] and a second high-voltage additive, fluoroethylene carbonate, represented by [Formula 2].
