The present invention relates to an electrolyte for a lithium metal battery. Specifically, an ionic liquid comprising cationic and anionic groups is used as an electrolyte for a lithium metal battery. Accordingly, the electrolyte is capable of inhibiting the growth of lithium dendrite by controlling the length of aliphatic chains coupled to the cationic groups, and capable of improving performance of the lithium metal battery with a small amount of additives. 본 발명은 리튬 금속전지용 전해질에 관한 것으로, 보다 상세하게는 양이온기와 음이온기를 포함하는 이온성 액체를 리튬 금속전지용 전해질로 사용하되, 상기 양이온기에 결합된 지방족 사슬의 길이를 제어하여 리튬 덴드라이트의 성장을 억제할 수 있고, 소량의 첨가제로도 리튬 금속전지의 성능을 향상시킬 수 있다.
