Summary:The present invention relates to an electrolyte for a lithium-sulfur battery and a lithium-sulfur battery comprising same, the electrolyte comprising a lithium salt, an organic solvent, and an additive, wherein the additive contains a compound represented by chemical formula 1 in which: R1 to R6 are the same as or different from each other and are each independently selected from the group consisting of hydrogen, heavy hydrogen, a substituted or unsubstituted C1 to C60 alkyl group, a substituted or unsubstituted C6 to C60 aryl group, a substituted or unsubstituted C1 to C60 alkoxy group, and a substituted or unsubstituted C6 to C60 aryloxy group; and at least one of R1 to R6 is not H. La présente invention concerne un électrolyte pour une batterie au lithium-soufre et une batterie au lithium-soufre le comprenant, l'électrolyte comprenant un sel de lithium, un solvant organique et un additif, l'additif contenant un composé représenté par la formule chimique 1 dans laquelle : R1 à R6 sont identiques ou différents l'un de l'autre et sont chacun indépendamment choisis dans le groupe constitué par l'hydrogène, hydrogène lourd, un groupe alkyle en C1 à C60 substitué ou non substitué, un groupe aryle en C6 À C60 substitué ou non substitué, un groupe alcoxy en C1 À C60 substitué ou non substitué, et un groupe aryloxy en C6 à C60 substitué ou non substitué ; et au moins l'un de R1 à R6 n'est pas H. 본 발명은 리튬염, 유기용매 및 첨가제를 포함하는 리튬-황 전지용 전해액에 있어서, 상기 첨가제는 화학식 1로 표시되는 화합물을 포함하며, 상기 화학식 1에 있어서 R1 내지 R6은 서로 같거나 상이하고, 각각 독립적으로 수소; 중수소; 치환 또는 비치환된 C1 내지 C60의 알킬기; 치환 또는 비치환된 C6 내지 C60의 아릴기; 치환 또는 비치환된 C1 내지 C60의 알콕시기; 및 치환 또는 비치환된 C6 내지 C60의 아릴옥시기로 이루어진 군으로부터 선택되며, 상기 R1 내지 R6 중 적어도 하나는 H가 아닌, 리튬-황 전지용 전해액 및 이를 포함하는 리튬-황 전지에 관한 것이다.
