Abstract

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.
