Polysulfide shuttling and sluggish sulfur redox kinetics hinder the cyclability and rate capability of lithium‐sulfur (Li‐S) batteries. Accelerating sulfur redox reactions is considered a promising way toward the capture and utilization of soluble sulfur species. Herein, topological insulator (TI) B...
