Designing Amino Functionalized Titanium-Organic Framework on Separators Toward Sieving and Redistribution of Polysulfides in Lithium-Sulfur Batteries

Caption

  • Amino could narrow the sub-nanopore size of Ti–MOF modified layer to around 0.8 nm for perfectly inhibiting polysulfides shuttle.
  • Amino enables redistribution and reutilization of blocked polysulfides via leveraging electrostatic adsorption.
  • Electrostatic adsorption and Lewis acid–base interaction make up for the deficiency of size effect in inhibiting polysulfides shuttle.
