Ultrafast Chemical Pre‐Sodiation of Pseudocapacitive CaV8O20 Anodes for High‐Performance Sodium‐Ion Capacitors

Advanced Science, EarlyView.
An ultrafast (2‐minute), gas‐free chemical pre‐sodiation strategy using Na‐benzophenone is developed to compensate for initial sodium loss in calcium vanadate (CaV8O20). Driven by the Ca2+ ‘spectator effect’, the framework enables highly reversible, quasi‐zero‐strain solid‐solution sodium storage, explicitly bypassing destructive conversion reactions ...

Architecting Phase‐Selective Interlayers for Stable SiOx Lithium Storage via Dual‐Function Design

Advanced Science, EarlyView.
Silicon anodes offer high capacity but suffer severe volume expansion. Silicon monoxide (SiO) buffers expansion, yet uncontrolled lithiation irreversibly consumes lithium as Li2O and oxygen‐rich silicates. Here, we design a layered SiOx featuring a phase‐selective conductive interfacial interlayer (PSCII), i.e., a Li4SiO4‐rich, ion‐accessible ...

Flame Suppression in Lithium‐Ion Batteries During Thermal Runaway Through Solvent Design Considering the Volatility–Flammability Relationship

Advanced Science, EarlyView.
An asymmetric sulfonate solvent forms thermally stable interphases and demonstrates non‐flammability, suppressing heat accumulation for safer, high‐performance lithium‐ion batteries. ABSTRACT An asymmetric sulfonate‐based linear solvent, 2,2,2‐trifluoromethyl mesylate (FMS), is designed and used as the primary solvent in liquid electrolytes to enhance ...

Reducing Ion Transport Friction by Mitigated Diluent‐Solvent Interaction for Sodium–Sulfur Battery

Advanced Science, EarlyView.
A local high‐concentration electrolyte to balance the ionic conductivity and interfacial stability is developed through replacing the high solvating DME with the moderate solvating diethyl ether to mitigate the diluent‐solvent interaction and reduce the local dynamic friction for Na+ transport, while maintaining the anion‐rich solvation clusters and ...

Thermochemical Core–Shell Architecturing of Si‐SWCNT Composites for High‐Performance Li‐Ion Battery Anodes

Advanced Science, EarlyView.
A thermochemically engineered core–shell Si architecture is developed through the controlled evolution of a SWCNT‐coated Mg2Si precursor. The process simultaneously generates a nanoporous Si shell for strain accommodation and Li+ transport, a chemically anchored SiC interfacial layer for robust mechanical and electrical coupling, and a Mg‐containing Si

Interfacial Interaction‐Engineered Dual Lithiophilic Ultrathin Interlayers for Dendrite‐Suppressed Lithium Metal Textile Anodes

Advanced Science, EarlyView.
Ultrathin lithiophilic interlayers engineered on a 3D textile electrode and separator cooperatively regulate interfacial Li nucleation and Li+ transport, leading to homogeneous Li plating and mitigated dendrite formation. The resulting dual‐interfacial design provides long‐term cycling stability, improved full‐cell durability, and a scalable pathway ...
