Tailored Redox‐Active Catholytes Enabling High‐Rate and High‐Loading All‐Solid‐State Lithium‐Sulfur Batteries

Advanced Materials, EarlyView.
This study explores iodine substitution in solid electrolytes to overcome sluggish redox kinetics and poor charge transport in all‐solid‐state Li‐S batteries. The resulting iodine‐rich, amorphous phase and superionic, nanocrystalline domains enable effective redox mediation and provide a robust ionic percolation network.

Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons

Advanced Materials, EarlyView.
Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses

Correlated Dual‐Gradient Electrodes Enabling Spatially Synchronized Sulfur Redox in High‐Mass‐Loading Li–S Batteries Under High Current Densities

Advanced Materials, EarlyView.
Coupling a dual‐gradient carbonized framework with Fe2O3/Fe‐N‐C catalytic sites enables spatially synchronized sulfur redox across the entire electrode thickness in high‐mass‐loading Li–S batteries. This synergistic structural–catalytic design effectively mitigates concentration, ohmic, and electrochemical polarization, thereby achieving high‐capacity ...
