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

摘要

The present invention relates to a binder for a lithium-sulfur battery, a positive electrode including the same, and a lithium-sulfur battery, and more particularly, to a binder for a lithium-sulfur battery including lithium polyacrylate and polyvinyl alcohol. Since the binder for a lithium-sulfur battery includes two specific polymers, the capacity and lifespan characteristics of the lithium-sulfur battery can be improved by improving the electrochemical properties and stability of the positive electrode.
