Atom-Dominated Relay Catalysis of High-Entropy MXene Promotes Cascade Polysulfide Conversion for Lithium-Sulfur Batteries

The high-entropy TiVNbMoC 3 MXene, with its atom-dominated relay catalysis effect and resilient lattice configuration, promotes a cascade of sulfur conversions and guides uniform Li + deposition, enabling shuttle-free and dendrite-free Li–S batteries.
