Preferentially oriented MnNCN nanosheets with high active (003) facets were synthesized by an aqueous weak solvent‐coordination strategy, and highly integrated MnNCN/CNT composite was in‐situ constructed as a high‐capacity fast‐charging anode. NCM811//MnNCN/CNT pouch cell exhibits a high energy density of 325 Wh kg−1 with a long cycle‐life over 200 ...

Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.

Metallic dissolution triggers Al/O vacancies in NiCoAl–CuO, steering C2‐selective ethanol oxidation to acetate. Hybrid electrolysis co‐produces hydrogen and acetate with high efficiency and reduced cell voltage. ABSTRACT Replacing the sluggish anodic oxygen evolution reaction (OER) with value‐added processes like the ethanol oxidation reaction (EOR ...

The Cu2O‐Bi2O3 thin film as a sacrificial interlayer at the back contact of kesterite solar cells achieves multiple synergistic optimizations in bulk defects, interface defects, back‐contact band offset, and MoSe2 properties. This enhances carrier separation, suppresses interface recombination, and enables DMSO‐processed kesterite devices to reach a ...

Coupling Atomic Confinement With CO2 Pressure for Selective and Stable CO2 Electroreduction
The coupling of high‐pressure operation with atomic‐scale catalyst design was investigated via an electrochemical cation implantation (ECI) process to create confined reaction environments over SnOx catalyst. The synergistic interplay between structural confinement and CO2 pressure was investigated, and the reaction mechanism for CO2RR to CO was ...

Tetrahydrothiophenium (Tht) ionic liquids bearing alkyl or ether side chains (one to four oxygen atoms) with FSA or TFSA anions were synthesized. Longer ether chains raised glass transition temperatures and viscosity while lowering conductivity. Short‐ether‐chain ILs, especially FSA‐based ones, exceeded 10−3 S cm−1 at 25°C, comparable to pyrrolidinium ...

From Potentiostatic to Galvanostatic Control in Pulsed Electrochemical CO2 Reduction to Ethylene
A two‐gap flow cell with three‐electrode configuration bridges the gap between H‐cells and industrial zero‐gap electrolyzers. Using ethylene‐selective CO2 reduction on copper as a model reaction, galvanostatic operation shows greater stability than potentiostatic control, whereas charge‐controlled pulsed protocols enable C2H4 selectivity under ...

Magnetic Supraparticles as Identifiers in Single‐Layer Lithium‐Ion Battery Pouch Cells
As an alternative to externally applied optical identifiers, magnetic supraparticles (SPs) can be used for contactless identification of lithium‐ion battery pouch cells via magnetic particle spectroscopy. This study validated the integration and detection of magnetic markers in three model scenarios.
