Two‐Dimensional Mesoporous Tungsten Oxynitride/Carbon Nanosheets: Enabling High‐Performance Lithium‐Sulfur Batteries

Lithium-sulfur batteries (LSBs) hold great promise as next-generation energy storage devices, owing to their ultrahigh theoretical energy density (2600 Wh kg^-1). However, their real-world implementation is limited by the polysulfide shuttle effect and the poor electrical conductivity of sulfur species. To address these problems and achieve high-performance LSBs, it is crucial to develop multifunctional catalysts featuring abundant active sites, short and accessible ion transport chann
