LITHIUM-SULFUR BATTERY

The present invention provides: i) a lithium-sulfur battery in which solid sulfur is introduced into an electrolytic region between a positive electrode and a negative electrode; ii) a lithium-sulfur battery comprising a middle layer containing elemental sulfur (S) or lithium sulfide (LiS) in an electrolytic region between a positive electrode and a negative electrode; and iii) a lithium-sulfur battery having a separator supporting sulfur particles or lithium sulfide particles between a positive electrode and a negative electrode.
