Title:
BINDER FOR LITHIUM-SULFUR BATTERY, POSITIVE ELECTRODE COMPRISING SAME, AND LITHIUM-SULFUR BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/132394
Kind Code:
A1
Abstract:
The present invention relates to a binder for a lithium-sulfur battery, a positive electrode comprising the same, and a lithium-sulfur battery and, more specifically, to a binder for a lithium-sulfur battery, the binder containing polyacrylic acid lithium and polyvinyl alcohol. The binder for a lithium-sulfur battery contains two kinds of particular polymers, and thus improves electrochemical characteristics and stability of the positive electrode, thereby improving capacity and lifespan characteristics of the lithium-sulfur battery.
