Beschreibung
Zusammenfassung:	The present invention relates to an electrolyte for a lithium secondary battery and a lithium secondary batter. The electrolyte comprises: a non-aqueous organic solvent lithium salt; a first additive represented by chemical formula 1; and a second additive represented by chemical formula 2. In the chemical formulas 1 and 2, the definition of each substituent is the same as the detailed description. The electrolyte for a lithium secondary battery according to an embodiment of the present invention is excellent in oxidative decomposition characteristics when operated at a high voltage. 리튬 이차 전지용 전해질 및 이를 리튬 이차 전지에 관한 것으로서, 이 전해질은 비수성 유기 용매 리튬염 및 하기 화학식 1로 표현되는 제1 첨가제 및 하기 화학식 2로 표현되는 제2 첨가제를 포함한다. [화학식 1][화학식 2](상기 화학식 1 및 2에서, 각 치환기의 정의는 상세한 설명과 동일하다.)
