Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons

Advanced Materials, EarlyView.
Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses

Prussian Blue Analog as a Functional Additive for Restoring Sulfide Solid Electrolytes: Enhancing Moisture Stability in All‐Solid‐State Batteries

Advanced Materials, EarlyView.
This work unveils the multifunctional roles of Prussian blue analogs (PBAs) within the LPSCl matrix, where they act as effective moisture scavengers and enable partial recovery of electrochemical performance. In addition, owing to their relatively soft nature, PBAs help mitigate interfacial stress and thereby enhance electrochemical stability and ...

Tin-phosphate glass anode for sodium ion batteries

APL Materials, 2013
The electrochemical property of tin-phosphate (designate as GSPO) glass anode for the sodium ion battery was studied. During the first charge process, sodium ion diffused into GSPO glass matrix and due to the reduction of Sn2+ to Sn0 state sodiated tin ...

Harnessing Chain Mobility via Protonation for Tough and Isotropic Hydrogel

Advanced Materials, EarlyView.
A protonation‐guided strategy enables ultra‐tough, isotropic PVA hydrogels by temporarily unlocking chain mobility via acidification and fixing homogeneous networks through salting‐out. The resulting materials simultaneously achieve high strength, extreme stretchability, and record‐level toughness, offering a generalizable route toward robust hydrogels

Superionic Amorphous Li2ZrCl6 and Li2HfCl6

Advanced Materials, EarlyView.
Amorphous Li2HfCl6 and L2ZrCl6 are shown to be promising solid‐state electrolytes with predicted ionic conductivities >20 mS·cm−1. Molecular dynamics simulations with machine‐learning force fields reveal that anion vibrations and flexible MCl6 octahedra soften the Li coordination cage and enhance mobility. Correlation between Li‐ion diffusivity and the
