Anomalous Enhancement in MXene‐Based Electrochemical Actuators: Pseudo‐Capacitance‐Induced Multi‐Charge Accumulation in Confined Space

Advanced Science, EarlyView.
We elucidate the electrochemical actuation mechanism of 2D material‐based electrodes within a MXene‐centered framework, linking atomic‐scale surface chemistry to macroscopic performance (see schematic). Mechanistically, the reduction of Ti─O─Ti sites in H2SO4 triggers the accumulation of hydrated ions at confined active sites, resulting in anomalous ...

Ru‐Doping‐Engineered Oxygen Vacancies in MoO3‐x Nanostructured Films With Ultrahigh Capacitance for Flexible Asymmetric Supercapacitors

Advanced Science, EarlyView.
Ru‐doping‐induced defect engineering enables freestanding Ru–MoO3‐x flexible films with enriched oxygen vacancies, modulated band structure, and enhanced charge transport. The optimized electrode delivers ultrahigh capacitance approaching the theoretical limit of MoO3, while assembled asymmetric supercapacitors exhibit high energy density, wide‐voltage

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 ...

Geometry‐Regulated Electrode‐Wide Nucleation Patterns in Aqueous Zinc Anodes

Advanced Science, EarlyView.
Laser‐ablated 3D hole patterning enables geometry‐driven control of Zn deposition in aqueous batteries. The hole opening ratio (HOR) governs electrode‐wide nucleation patterns by regulating the spatial distribution of nucleation sites and the evolution of early‐stage Zn deposits.

Basal Plane Graphene Coated Zn Powder for High Performance Aqueous Zn Metal Batteries

Advanced Science, EarlyView.
A mechanofusion‐driven dry coating forms a hydrophobic graphene shell on Zn powder, stabilizing the electrode‐electrolyte interface. This basal‐plane‐rich protective layer modifies the Zn2+ solvation environment and promotes preferential growth along the (002) plane, suppressing dendrite and parasitic reactions.

Bio‐Inspired Oligocellulose‐Regulated Ice‐Water Interfaces Enable Sustained Ion Transport in Frozen Aqueous Zinc Batteries

Advanced Science, EarlyView.
Inspired by antifreeze glycoproteins (AFGPs), we synthesized a type of oligomeric cellulose (OC‐8) to inhibit ice formation and enlarge the inter‐ice water channel for transportation. Typical confocal fluorescence experiments display the expansion of the ice‐water interface for zinc‐ion transport.
