The present disclosure relates to a lithium sulfur battery comprising a negative electrode and a positive electrode disposed opposite to each other, a separator positioned between the negative electrode and the positive electrode, and a gel polymer electrolyte positioned between the separator and the positive electrode, wherein the gel polymer electrolyte comprises LiNO. The present disclosure relates to a lithium sulfur battery preventing degeneration caused by a shuttle effect, and the lithium sulfur battery comprises a gel polymer electrolyte configured to inhibit a transfer of a polysulfide-based material to a negative electrode so as to prevent a loss of the polysulfide formed on a positive electrode surface during charge and discharge reactions, whereby, lifespan characteristics of the lithium sulfur battery are capable of being enhanced.
