Passivation‐Induced Species Dynamics and Microstructural Evolution in Solid‐State Lithium–Sulfur Cathodes

Advanced Science, EarlyView.
The formation of insulating Li2S during discharge in solid‐state lithium–sulfur batteries passivate reaction sites and limits sulfur utilization. In this work, a microstructure‐resolved modeling framework coupling transport and reaction kinetics is developed to predict charge–discharge behavior and reveal particle‐scale species evolution and incomplete

Heterostructure‐Engineered Conductive MOFs Coupled with MoSe2@MXene Framework for Efficient and Selective Lithium Extraction from Salt Lake Brine via Capacitive Deionization

Advanced Science, EarlyView.
This schematic illustrates a capacitive deionization (CDI) system for the selective extraction of lithium from salt‐lake brine. The system employs a cathode fabricated from the Fe‐THBQ@MoSe2@MXene composite alongside an activated carbon (AC) anode. Upon applied voltage, the cathode demonstrates high efficiency in capturing Li+ ions while effectively ...

Interfacially Reinforced Crosslinked Binder with Structural Integrity for Stable Micro‐Sized Silicon Anodes in All‐solid‐state Batteries

Advanced Science, EarlyView.
ABSTRACT All‐solid‐state batteries (ASSBs) have attracted considerable attention as next‐generation energy storage systems owing to their high energy density and safety. However, their performance is critically limited by insufficient solid–solid interfacial contact and severe chemomechanical degradation, particularly for micro‐sized silicon (µSi ...

Tailored Redox-Active Catholytes Enabling High-Rate and High-Loading All-Solid-State Lithium-Sulfur Batteries. [PDF]

Adv Mater
This study explores iodine substitution in solid electrolytes to overcome sluggish redox kinetics and poor charge transport in all‐solid‐state Li‐S batteries. The resulting iodine‐rich, amorphous phase and superionic, nanocrystalline domains enable effective redox mediation and provide a robust ionic percolation network.
