Intercalation‐Conversion Hybrid Cathode Enabled by MXene‐Driven TiO<sub>2</sub>/TiS<sub>2</sub> Heterostructure for High‐Energy‐Density Li–S Battery
Lithium–Sulfur Batteries In article number 2400196, Seung-Mo Lee and co-workers introduce a sea-urchin-like TiO2/TiS2 heterostructure, synthesized through the complete sulfurization of multilayer MXene, as a novel sulfur host in lithium–sulfur batteries. This host not only offers substantial adsorption capability and a bidirectional electrocatalytic effect to accelerate conversion reactions but also provides additional capacity through intercalation reactions. This results in an intercalation-conversion hybrid cathode with high energy density.
