3D Interconnected Zn‐Ion Pathways Through Anionic Nanochannels Surrounding Bacterial Cellulose Nanofibers by Repetitive Interfacial Assembly for Aqueous Zn‐Ion Battery Separators

open access: yesAdvanced Energy Materials, EarlyView.
A repetitive interfacial assembly method is introduced to prepare a nanofibrillar separator with interconnected 3D anionic nanochannels for aqueous zinc‐ion batteries. The carboxylate‐rich nanochannels promote enhancements of Zn2+ ion transport and charge transfer at the electrode surface, and the 3D nanostructured hydrogels contribute to homogeneous ...

Disorder‐Driven Fast Na+ Transport: From Crystalline to Amorphous Networks in the Mixed‐Anion NaTaOxCl6−2x Oxychlorides

open access: yesAdvanced Energy Materials, EarlyView.
Oxygen substitution in NaTaOxCl6‐2x drives structural evolution from isolated [TaCl6]– octahedra, through oxygen‐bridged [Ta2OCl10]2– dimers, toward extended trans‐[TaO2Cl4]3– chain‐like arrangements. At intermediate compositions, zero‐dimensional corner‐sharing motifs are proposed to create a flexible, disordered framework that peaks ionic ...

In Situ Evolution of Artificial Interphase Enabling Stable, High‐Performance Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
An evolutionary artificial interphase is presented for stable lithium metal batteries. A Mg3N2‐based layer spontaneously evolves into a hybrid interphase enriched with superionic Li3N and lithiophilic Mg‐Li alloy during cycling. This dynamic, self‐reinforcing mechanism effectively suppresses dendrite growth and enables exceptional long‐term cycling ...

Mechanisms of Alkali Ionic Transport in Amorphous Oxyhalides Solid State Conductors

open access: yesAdvanced Energy Materials, EarlyView.
Large‐scale machine learning‐based molecular dynamics simulations are used to investigate isovalent amorphous oxyhalides, revealing a remarkable chemically independent ionic conductivity. A rigorous analysis of alkali residence times across different metal–anion environments identifies divalent anions as key diffusion bottlenecks.

Tunnel‐Framework Interphase Driving Rapid Zn2+ Diffusion for Long‐Life Zn Metal Anodes

open access: yesAdvanced Energy Materials, EarlyView.
The construction of an artificial interphase with 3D tunnel‐framework effectively suppresses interfacial water‐induced side reactions and dendrite growth. ABSTRACT Aqueous zinc‐ion batteries (AZIBs) are presently attracting considerable interest for large‐scale energy storage owing to their low cost and high safety.

CFD modeling and sensitivity‐guided design of silicon filament CVD reactors

open access: yesAIChE Journal, EarlyView.
Abstract Filament‐based chemical vapor deposition (CVD) for silicon (Si) coatings is often treated as an adaptation of planar deposition. But this overlooks fundamental shifts in transport phenomena and reaction kinetics. In filament CVD, the filament acts as a substrate, heat source, and flow disruptor simultaneously. In this work, we ask: What really
