Abstract
A capsule for a lithium-sulfur secondary battery, wherein the capsule includes a core containing a material required for formation and restoration of a solid electrolyte interface layer (SEI layer) and a shell including a polymer surrounding the core. The shell maintains the material required for formation and restoration of the solid electrolyte interface layer (SEI layer) at a constant level during operation of the battery, thereby exhibiting the effect of maintaining the solid electrolyte interface layer (SEI layer) on the negative electrode for a long time.
