The present invention provides a binder for a positive electrode of a lithium-sulfur secondary battery, comprising an acrylic polymer including an acrylic monomer polymerized unit, a non-acrylic monomer polymerized unit and a redox monomer polymerized unit. The acrylic polymer contains at least 30 wt.% of the acrylic monomer polymerized unit. In addition, the present invention provides a positive electrode active layer, a positive electrode and a lithium-sulfur secondary battery manufactured using the binder. |
