Abstract: The present invention relates to an electrolyte for a lithium sulfur battery and a lithium sulfur battery using the same. The electrolyte for a lithium sulfur battery of the present invention includes lithium polysulfide in the electrolyte, so as to prevent sulfur compounds from eluting from anode materials including sulfur, and to improve the stability of the electrolyte. As a result, the side effect, caused by the reaction between the eluted sulfur compounds and cathode, is prevented, thereby presenting stable lifespan properties.
