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.
Claims14
A lithium sulfur battery, comprising:
- a positive electrode including a conductive material;
- a lithium metal negative electrode;
- a separator located between the positive electrode and the negative electrode;
- and
- an electrolyte including a nonaqueous organic solvent and a lithium salt between the positive electrode and the negative electrode,
- wherein solid sulfur is introduced into an electrolyte solution region between the positive electrode and the negative electrode, and the solid sulfur introduced into the electrolyte region is added to an electrolyte solution so that the solid sulfur is dispersed in the electrolyte solution.
