A positive electrode for a lithium-sulfur battery includes a positive active material including a sulfur-based compound, an electrically conductive material, an agent for increasing viscosity, and a binder. The agent is selected from a cellulose-based compound, an ionically conductive polymer, and a mixture thereof. The binder includes styrene-butadiene rubber.

Positive electrode for lithium-sulfur battery

A positive active material for a rechargeable lithium-sulfur battery includes a core of a sulfur compound and a surface-passivation layer formed on the core. The surface-passivation layer is made of a coating-element-included compound selected from the group consisting of a coating-element-included hydroxide, a coating-element-included oxyhydroxide, a coating-element-included oxycarbonate, a coating-element-included hydroxycarbonate, a mixture thereof.
