Imidazole-Containing Ether-Free Polyaromatics with Self-Aggregating Piperidinium Side Chains for Alkaline-Stable Anion Exchange Membranes

Abstract Despite being critical components of anion exchange membrane water electrolyzers (AEMWEs), anion exchange membranes (AEMs) still confront substantial bottlenecks in meeting operational requirements due to inadequate alkaline stability and ionic conductivity. In this work...

Preprint of "Beyond Steady-State Limitations of Electrochemical Impedance Spectroscopy: Time-Resolved Decoupling of Transient Processes"

Electrochemical Impedance Spectroscopy (EIS) is a powerful tool for separating individual processes in electrochemical systems. However, conventional EIS requires the system to remain stationary during measurement, thereby limiting its applicability to transient phenomena. In thi...

Preprint of "Cobalt Oxidation State Controls Ir–CoOₓ Catalysts for Acidic Oxygen Evolution: From Model Surfaces to PEM Water Electrolyzers"

Water electrolysis is a key technology for sustainable hydrogen production, yet its efficiency in proton exchange membrane (PEM) electrolyzers is limited by the sluggish oxygen evolution reaction (OER) and the high cost of iridium-based catalysts. Combining Ir with Co and its oxi...

Preprint of "A Laterally Conductive Mesh Interphase Enables Spatially Extended Zinc Deposition for Aqueous Zinc Batteries"

Zn metal anodes often fail because interfacial reactions become increasingly localized during cycling, leading to uneven deposition and dendrite growth. Existing artificial interphases can mitigate side reactions or regulate nucleation, but they rarely regulate the interfacial el...
