Atomic Layer Deposition‐Modified Bifunctional Electrocatalysts for Rechargeable Zinc‐Air Batteries: Boosting Activity and Cycle Life

open access: yesAdvanced Energy Materials, EarlyView.
The transition metal oxide is precisely deposited on the catalyst surface via atomic layer deposition (ALD), forming a protective layer with catalytic activity. Electrochemical experiments, theoretical calculations, and in situ X‐ray absorption spectroscopy (XAS) battery testing collectively demonstrate that the modified transition metal oxide ...

How Halide Segregation Governs the Ion Density Evolution and Ionic Performance Losses: From Degradation to Recovery

open access: yesAdvanced Energy Materials, EarlyView.
Halide segregation (HS) in mixed‐halide wide‐bandgap (WBG) perovskites is key to the stability of perovskite‐based tandem cells and a central focus of large‐scale research efforts. Here, we find that the underlying reason for the poor stability of cells prone to HS is enhanced ionic losses during operation. Furthermore, we identified irreversible ionic

Insight‐Guided Optimization of the Individual Steps in Ambient Slot‐Die‐Coated Perovskite Solar Cells

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This graphical abstract presents an integrated workflow for optimizing perovskite thin film fabrication by tuning ink rheology, refining processing parameters, and controlling crystallization. Viscosity control and process optimization precisely regulate wet film thickness and drying time, while crystallization directed by solvent additives yields ...

Transient modeling of extraction columns: Parameter estimation, uncertainty analysis, and operation optimization

open access: yesAIChE Journal, EarlyView.
Abstract Despite extensive modeling efforts in extraction research, transient column models are rarely applied in industry due to concerns regarding parameter identifiability and model reliability. To address this, we analyzed uncertainty propagation from estimated parameters in a previously introduced column model and assessed identifiability via ill ...

Kern‑Schale: Versiegelung nanoporöser Partikel mit semipermeablen Kohlenstoffschichten befreit Hartkohlenstoffanoden von ihrem Dilemma

open access: yesAngewandte Chemie, EarlyView.
Eine Kern‐Schale‐Strategie wird vorgestellt, um die hohen Verluste nichtgraphitischer Hartkohlenstoffanoden zu überwinden. Aktivkohle wird durch Gasphasenabscheidung mit einer semipermeable Kohlenstoffschicht versiegelt, wodurch die SEI‐Bildung und Natriumspeicherung räumlich getrennt werden.
