Redox‐Mediated Aluminum–Air Fuel Cells With Suppressed Hydrogen Evolution for Durable Power Generation

Advanced Energy Materials, EarlyView.
The redox‐mediated aluminum–air fuel cell (RM‐AAFC) integrates a soluble redox mediator, 7,8‐dihydroxy‐2‐phenazine sulfonic acid (DHPS), to facilitate the oxidation of aluminum and inhibit hydrogen evolution reaction (HER) through competitive reactions between DHPS reduction and HER on the Al surface.

Natural Anionic Interfacial Reconstruction for Suppressing Pitting Corrosion Enables Durable Seawater Zinc‐Ion Batteries

Advanced Energy Materials, EarlyView.
In situ electrochemically induced molecular sieve‐alginate interface layer can suppress chloride‐induced pitting corrosion, hydrogen evolution, and dendrite growth, while regulating zinc ion transport and deposition, thereby protecting the zinc anode in seawater electrolyte.

Pyridine‐Isomerism‐Driven Spin Engineering at a COP‐Fe3O4 Interface for High‐Performance Oxygen Reduction Electrocatalysis

Advanced Energy Materials, EarlyView.
Strategically adjusting the pyridine nitrogen position in the polymer matrix (pyridine isomerism) intensifies its interaction with embedded Fe3O4 nanocrystals. This enhanced interaction induces a spin‐state transition in Fe from low‐spin to intermediate‐spin, accompanied by refined d‐orbital properties.

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

Advanced 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.

Donor–Acceptor Covalent Organic Framework Enables Ambipolar Charge Storage in Aluminum‐Ion Energy Storage

Advanced Energy Materials, EarlyView.
A donor–acceptor covalent organic framework is designed as an ambipolar cathode for aluminum‐ion energy storage. The crystalline, microporous architecture enables intrinsic charge transport without conductive additives. Multi‐electron redox activity at donor and acceptor sites supports high capacity, excellent stability, and efficient reversible ...

Flame‐Retardant Quasi‐Solid‐State Electrolytes From Self‐Assembled Azolate Hybrid Frameworks for Highly Safe Lithium Batteries

Angewandte Chemie, EarlyView.
This work develops a spray‐assisted in situ assembly technique to construct AHF materials with nitrogen/oxygen‐regulated one‐dimensional channels on glass fiber, providing abundant active sites and enabling rapid transport for lithium ions. Subsequently, phosphate flame retardants are encapsulated via in situ polymerization, resulting in a thermally ...
