Abstract
The present invention provides a lithium-sulfur battery with a polysulfide confining layer, which can prevent loss of polysulfide formed on the surface of a positive electrode during charge and discharge reactions, thus improving the durability of the battery. For this purpose, the present invention provides a lithium-sulfur battery including a hydrophilic polysulfide confining layer interposed between a positive electrode and a separator to prevent a polysulfide-based material from being lost from the surface of the positive electrode during discharge.
