Ultra‐Low Dosage Lignin Binder for Practical Lithium–Sulfur Batteries (Adv. Energy Mater. 17/2023)

Li–S Batteries In article number 2300092, Yong Qian, Jun Lu, Xueqing Qiu, and co-workers develop a biomass lignin-based binder for practical Li–S batteries. It endows the active/conductive/current collector materials in the cathode with strong and balanced adhesion at an ultra-low dosage of 2 wt%, and the as-prepared cathode used in a pouch cell delivers an energy density over 484 Wh kg−1 and excellent cycling stability over 100 cycles.
