Synergistic Integration of Fe-N₄ Single-Atom Sites and Directionally Aligned Electrode Architecture for High-Performance Lithium-Sulfur Batteries. [PDF]

Adv Sci (Weinh)
A directionally ice‐templated sulfur cathode integrated with atomically dispersed Fe–N4 catalytic sites is developed for high‐performance lithium–sulfur batteries. The structure–catalysis synergy accelerates Li+ transport and polysulfide conversion, leading to high sulfur utilization and stable long‐term cycling performance.

Predicting the Stepwise Growth of Lithium Clusters Around Sulfur Species (S and S₂) From the Topology of the Electron Localization Function. [PDF]

J Comput Chem
Hyperlithiated sulfur species: an ELF analysis. ABSTRACT In this work, we present a theoretical investigation of sulfur‐doped lithium clusters, namely LinS and LinS2 (n = 1–10), with the aim of elucidating the mechanism governing the stepwise growth of lithium around sulfur centers. The equilibrium geometries of all clusters were first determined using

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...
