Advanced Materials, EarlyView.Interfacial reactions in all‐solid‐state batteries are conventionally suppressed; here, they are designed. Vacancy‐rich β‐Li3N, acting as an anolyte, reacts controllably with silicon during composite anode fabrication, building a purpose‐made lithium nitridosilicate interlayer on every particle surface.

Atomic-scale phase separation induced clustering of solute atoms
Nature Communications, 2020 Dealloying usually relies on chemical dissolution of an alloy component. By contrast, the authors demonstrate an atomic-scale phase separation process that differs completely from the chemical dealloying mechanism and thus represents a significant ...

Observing Electrochemical Dealloying by Single-Nanoparticle Collision
, 2016 We report direct observation of electrochemical and thermal dealloying processes of individual metal alloy nanoparticles (NPs). Electrochemical dealloying of single Ag–Hg alloy NPs was achieved in a basic solution (e.g., pH 13) by oxidizing Hg under ...

Angewandte Chemie, EarlyView.Trace Mg doping into gallia–alumina generates hole‐type oxygen species that accelerate hydrogen recombination, eliminating the need for Pt promotion. The fully oxide‐based catalyst resists sintering under repeated regeneration, outperforming benchmark PtSn and CrOx catalysts with exceptional stability over 30 dehydrogenation–regeneration cycles ...

Advanced Materials Interfaces, EarlyView.This study proposes a function‐sharing anode design to enable nonmetallic lithium insertion while maintaining intimate interfacial contact with the solid‐state electrolyte. A combination of lithium‐compatible and conformable borohydrides, highly conformable indium metal, less‐graphitized acetylene black, and a layer of highly graphitized massive ...
