Toward Energy Efficient Electrochemical Valorization of Waste Nitrate and Sulfide

Advanced Materials, EarlyView.
This work introduces an integrated electrochemical strategy couples nitrate reduction with sulfide oxidation for energy‐efficient wastewater valorization. A Cu‐Co dual‑site catalyst, engineered for close proximity, promotes *NO2 relay and subsequently NH3 formation, enabling the system to operate at substantially reduced cell voltages and produce high ...

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

Advanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

An Integrated Stainless Steel‐Based Electrode for Durable Direct Natural Seawater Electrolysis

Advanced Materials, EarlyView.
We report an integrated stainless steel‐based electrode featuring Pt atomic clusters anchored on a NiFe‐LDH anticorrosive layer. By regulating interfacial water dynamics to suppress chloride attack, this hierarchical architecture achieves superior durability (over 1000 h) and energy efficiency in direct seawater electrolysis, offering a cost‐effective ...

Impact of Anode to Cathode Crossover in Lithium‐metal Batteries With High‐Nickel Cathodes

Advanced Materials, EarlyView.
Anode‐to‐cathode chemical crossover is identified as a critical degradation mechanism in lithium‐metal batteries. Full‐cell experiments with high‐Ni layered oxide cathodes and localized high‐concentration electrolytes reveal accelerated cathode impedance growth and CEI thickening driven by lithium‐metal anodes. The findings underscore the importance of

A Quasi‐Solid Ionic Liquid‐Polymer Hybrid Electrolyte for Shuttle‐Free and Dendrite‐Free Aqueous Zinc─Bromine Batteries

Advanced Materials, EarlyView.
A quasi‐solid ionic liquid‐polymer hybrid electrolyte is proposed to achieve shuttle‐free and dendrite‐free aqueous Zn─Br batteries. Synergetic effects between Zn2+ selective conduction of polyanionic network and polybromide complexing additive suppress the shuttle effect and improve Zn reversibility.
