Active Site Determination of Heterogenized Molecular Electrocatalysts

Advanced Energy Materials, EarlyView.
Here, we develop a methodology to examine the active site availability of immobilized transition‐metal molecular complexes via cyclic voltammetry. By using varying loadings of the molecular complex FeTPP physically immobilized onto Vulcan Carbon, we show the influences of FeTPP/VC ratios on the total number of active sites.

Enabling Long Term, Shelf‐Stable Perovskite Solar Cells: Alumina Barriers to Protect Perovskite Devices from Moisture and Oxygen

Advanced Energy Materials, EarlyView.
This study reports a packaging strategy for perovskite photovoltaic devices using atomic layer deposition (ALD) of aluminum oxide. Through optimization of deposition temperature and oxidant chemistry, researchers develop a 50 nm barrier layer with superior water vapor (WVTR) and oxygen transmission rates (OTR).

Engineering Trace‐Amount Electrolyte Additives for Aqueous Zinc Batteries

Advanced Energy Materials, EarlyView.
Large‐amount additives primarily modify the bulk electrolyte by coordinating with Zn2+ or reshaping the hydrogen‐bond network, thereby altering the overall solution chemistry. In contrast, trace‐amount additives mainly operate at the electrode–electrolyte interface, regulating Zn deposition through electric double‐layer modulation, interfacial ...

3D Interconnected Zn‐Ion Pathways Through Anionic Nanochannels Surrounding Bacterial Cellulose Nanofibers by Repetitive Interfacial Assembly for Aqueous Zn‐Ion Battery Separators

Advanced Energy Materials, EarlyView.
A repetitive interfacial assembly method is introduced to prepare a nanofibrillar separator with interconnected 3D anionic nanochannels for aqueous zinc‐ion batteries. The carboxylate‐rich nanochannels promote enhancements of Zn2+ ion transport and charge transfer at the electrode surface, and the 3D nanostructured hydrogels contribute to homogeneous ...

Atomistic Insights Into Lithium Alloying and Crystallization at Metal Interlayers in Zero‐Excess Lithium Batteries

Advanced Energy Materials, EarlyView.
Molecular dynamics simulations with machine learning potentials, combined with experiments, reveal how interlayer metals govern Li alloying and crystallization in zero‐excess lithium batteries. Mg and Zn promote solid‐solution alloy‐mediated pathways that influence Li diffusion and structural uniformity, while Bi forms ordered intermetallics with more ...
