Te‑Modulated Fe Single Atom with Synergistic Bidirectional Catalysis for High‑Rate and Long–Cycling Lithium‑Sulfur Battery

Caption

  • The Te modulator induces a polarized charge distribution to optimize the electronic structure of the central Fe site, elevating the d-band center and enhancing the density of states near the Fermi level.
  • Strengthened d-p orbital hybridization between the catalyst and sulfur species optimizes the adsorption behavior toward LiPSs and facilitates the bidirectional redox process of Li-S batteries.
  • The Fe-Te atom pair catalyst endows Li-S batteries remarkable rate performance, extraordinary cycling stability and anticipated areal capacity
