Vegetable Oil‐Based Waterborne Polyurethane as Eco‐Binders for Sulfur Cathodes in Lithium–Sulfur Batteries

Lithium–sulfur batteries (LSBs) suffer from well‐known fast capacity losses despite their extremely high theoretical capacity and energy density. These losses are caused by dissolution of lithium polysulfide (LiPS) in ether‐based electrolytes and have become the main bottleneck to widespread applications of LSBs. Therefore, there is a significant need for electrode materials that have a strong adsorption capacity for LiPS. Herein, a waterborne...
