Engineering Dynamic Electrolyte Microenvironments via Double-Shell Hosts for Practical Lithium–Sulfur Batteries

Caption

  • The efficient preparation of sulfur hosts derived from Prussian blue analogues with double-shell hollow structure was achieved through ion exchange with precisely controlled elemental ratios.
  • The double-shell structure alters the microenvironment of sulfur redox reaction through self-driven dynamic migration of electrolyte, preventing the local enrichment of lithium polysulfides around catalysts.
  • The double-shell sulfur cathode enhances the cycling stability and practical application of lithium–sulfur batteries, enabling an Ah-level pouch cell with an energy density of 454.7 Wh kg–1.
