BINDER FOR LITHIUM-SULFUR BATTERY, POSITIVE ELECTRODE COMPRISING SAME, AND LITHIUM-SULFUR BATTERY

摘要

A binder for a lithium-sulfur battery, and a positive electrode and a lithium-sulfur battery including the same, and in particular, to a binder for a lithium-sulfur battery including lithium polyacrylate and polyvinyl alcohol. By including two types of specific polymers, the binder for a lithium-sulfur battery is capable of enhancing electrochemical properties and stability of a positive electrode, and thereby enhancing capacity and lifetime properties of a lithium-sulfur battery.
