Abstract: The present invention provides a lithium-sulfur thermal battery including: a positive electrode including sulfur (S8) or a sulfur compound, and a solid electrolyte including a lithium salt and a polymer having a melting point lower than a melting point of a negative electrode; a lithium metal negative electrode or lithium alloy; a solid electrolyte membrane disposed between the positive electrode and the negative electrode and including a lithium salt and a polymer having a melting point lower than a melting point of the lithium metal negative electrode or lithium alloy; and a heater configured to provide heat so that the polymer is melted.

Abstract: Provided is an active material separation-type lithium-sulfur battery including a non-sulfur-based positive electrode and a non-aqueous electrolyte solution including active sulfur, which is capable of realizing enhanced battery capacity.

Abstract: 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 (S8) or lithium sulfide (Li2S) 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.
