Zusammenfassung:	The present invention relates to a non-aqueous electrolyte for a lithium secondary battery and a lithium secondary battery. The non-aqueous electrolyte of the present invention comprises: a non-aqueous organic solvent; a lithium salt; a first additive including at least one of compounds represented by the following chemical formulas 1 to 4; and a second additive including at least one of compounds represented by the following chemical formula 5 or 6. (In the chemical formulas 1 to 6, the definition of each substituent is as defined in the detailed description.) 리튬 이차 전지용 비수 전해질 및 이를 리튬 이차 전지에 관한 것으로서, 이 비수 전해질은 비수성 유기 용매; 리튬염; 하기 화학식 1 내지 4로 표현되는 화합물 중 적어도 하나를 포함하는 제1 첨가제; 및 하기 화학식 5 또는 6으로 표현되는 화합물 중 적어도 하나를 포함하는 제2 첨가제를 포함하는 것이다. [화학식 1][화학식 2][화학식 3][화학식 4][화학식 5][화학식 6](상기 화학식 1 내지 6에서, 각 치환기의 정의는 상세한 설명과 동일하다.)
