Accelerated Sulfur Evolution Reactions by TiS2/TiO2@MXene Host for High‐Volumetric‐Energy‐Density Lithium–Sulfur Batteries (Adv. Funct. Mater. 35/2023)

Lithium-Sulfur Batteries In article number 2303503, Seung-Mo Lee and co-workers report an advanced sulfur host material in the form of TiS2/TiO2 heterostructures grown on Ti3C2Tx Mxene. Thanks to the balanced adsorption-catalysis synergistic effect generated by TiS2/TiO2, the TiS2/TiO2@MXene host effectively inhibits the shuttle effect and accelerates the conversion reactions of lithium polysulfides, thereby enabling high-performance Li-S batteries with excellent cyclability and high energy density.
