Abstract
A positive electrode for a lithium-sulfur battery and a lithium-sulfur battery including the same, and in particular, a positive electrode for a lithium-sulfur battery including an active material, a conductive material, a binder and an additive, wherein the additive includes an organic acid lithium salt, the organic acid lithium salt including a dicarboxyl group. By including a dicarboxyl group-including organic acid lithium salt as the additive, the positive electrode for the lithium-sulfur battery is capable of enhancing capacity and lifetime properties of the lithium-sulfur battery through enhancing lithium ion migration properties.
