Molecular Damping Effect of Trace Additives Enhances Zinc Anode Stability Under High Depth of Discharge

open access: yesAdvanced Science, EarlyView.
Inspired by the energy dissipation from damping effects, this work employs trace amounts of weakly adsorbing additives to form an adapted interface on the Zn anode. Unlike the water‐deficient interfaces formed by strongly adsorbing additives, this adapted weakly adsorbing interface enables the regulation of electric field disturbances at higher depths ...

Medium‐Entropy Engineering Enhances Na⁺/Electron Transport in Na3Fe0.1Mn0.2Co0.2Ni0.3V1.2(PO4)2F3@CNTs Cathode for Sodium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
This study proposes a medium‐entropy strategy to enhance sodium vanadium fluorophosphate cathodes. The designed Na3Fe0.1Mn0.2Co0.2Ni0.3V1.2(PO4)2F3@CNTs composite enhances structural stability and charge transport. Entropy‐induced distortion and carbon nanotubes (CNTs) synergistically improve Na⁺/electron kinetics. In situ XRD reveals a reversible dual‐

Deformation Behaviors in Single BCC‐Phase Refractory Multi‐Principal Element Alloys under Dynamic Conditions

open access: yesAdvanced Science, EarlyView.
Exceptional mechanical stability of refractory multi‐principal element alloy (RMPEA) across various strain‐rates and temperature is studied through multiscale experiments coupled with theoretical calculations. This stability originates from competition between twinning and adiabatic heating during dynamic deformation, contributed from severe lattice ...

Cation‐Engineered Gradient Interfacial Structure Toward Dendrite‐Free and Shuttle‐Free Aqueous Zn‐Iodine Batteries

open access: yesAdvanced Science, EarlyView.
This paper proposes an “EDL‐directed regulator” strategy that constructs hydrophobic‐hydrophilic gradient interfaces to stabilize Zn anode by forming a water‐poor EDL and lowering the desolvation barriers Zn2+. Meanwhile, the ACh+‐containing electrolyte suppresses polyiodide shuttling via electrostatic capture, enhancing the long‐term reversibility and

Electrochemistry as a Tool for Redox‐Based Bio‐Information Processing

open access: yesAdvanced Science, EarlyView.
Redox is a modality that is native to biology and accessible to electronics through electrochemistry. Imposed electronic inputs are transduced into redox signals that can probe for bio‐information or actuate biological responses. Measured electronic output responses are analyzed to reveal actionable information.

Electroplating Carbon Nano‐Onion on Copper for Dendrite‐Free and Anode‐Free Zinc‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Zinc‐ion batteries are emerging as safe and cost‐effective alternatives to lithium‐ion batteries, but suffer from dendrite formation and unstable anodes. An electroplating approach for preparing a carbon nano‐onion (CNO)‐embedded‐Cu layer on Cu foil is presented, which enables highly reversible zinc plating/stripping (99.89% efficiency over 1400 cycles)
