🔋 Interested in fast-charging batteries? A paper by MAPEX member Fabio La Mantia and his colleagues in the journal Electrochimica Acta takes a closer look at the electron-transfer reaction between electrode and redox pair – the fundamental phenomenon in all electrochemical systems. "By analyzing this reaction under different salt concentrations," explains La Mantia, Professor at the Institute for Production Engineering at Universität Bremen, "we have demonstrated that the classic textbook description of the electron-transfer reaction does not always apply. Instead the reaction should be described as a coupled electron- and ion-transfer. This has strong implications in understanding the reactions behind hydrogen production and fast-charging batteries, among other technologies."

Excited to share my research on the electrochemical behaviour of glassy carbon electrodes in vanadium flow batteries! This study explores the impact of repeated anodic and cathodic treatments on electrode activity, using cyclic voltammetry and electrochemical impedance spectroscopy to track activity in the VII-VIII and VIV-VV redox reactions. We observed that electrode activity initially increases with the number of treatment steps, independent of the treatment potential. However, as treatments continue, a distinct potential-dependent behavior emerges, allowing the electrode's activity to be toggled between enhanced and inhibited states by simply adjusting the applied potential. These findings indicate that the surface functional groups may play a key role in this fascinating behaviour. https://lnkd.in/eXGJvcKa ECS - The Electrochemical Society Case Western Reserve University #electrochemistry #vanadiumflowbattery #energystorage #materialscience #research

🚀 Exciting Advances in PEM Water Electrolysis! 🌊🔋 To discuss recent research advancements in the performance and stability of Proton Exchange Membrane Water Electrolyzers (PEMWEs), it utilized cutting-edge materials characterization techniques like Scanning Electron Microscopy (SEM) and micro-XRF mapping to analyze catalyst layers in different cell designs. The findings reveal significant differences in catalyst utilization and morphology, which are crucial for enhancing efficiency. 🔍 Key Highlights ✅ Catalyst Layer Morphology: CCE-based anode catalyst layers exhibited a uniform porous structure, while CCMs displayed a smooth morphology due to decal transfer. This impacts catalyst performance and longevity. ✅ Impact of Conditioning: Our polarization analyses demonstrated that conditioning protocols significantly affect cell performance. High current conditioning led to lower cell voltages and improved efficiency, particularly in liquid-fed systems. ✅ Titanium Incorporation: We observed that titanium ions can migrate under certain conditions, potentially impacting cell performance. Understanding this mechanism is essential for future designs. 🧿 These findings pave the way for more efficient and durable PEMWEs, which are critical for sustainable hydrogen production. The implications for clean energy are immense! Looking forward to connecting with fellow researchers and industry professionals to discuss these findings and explore collaborative opportunities.💡🤔🔮 🤝 Stay Updated: Follow me for the latest news and insights!

In a novel study, researchers at the University of Twente have made significant strides in understanding the behaviour of micro- and #nanobubbles on #electrodes during water #electrolysis, a process crucial for #greenhydrogen production. These tiny bubbles form on the electrodes, blocking the flow of #electricity and reducing the #efficiency of the reaction.   Supported by advanced molecular simulations, Detlef Lohse and his team have developed a theory that can successfully predict the electrical current density needed to allow the nanobubbles to grow uncontrollably and detach, thus freeing the electrode for further #hydrogen production. This finding is pivotal as it enables the prediction and control of bubble behaviour, ensuring that electrolysis can proceed with minimal disruption. The research builds upon the established stability theory for surface nanobubbles (the Lohse-Zhang model) and extends it to include the #electrolytic current density to predict bubble behaviour.   With this improved knowledge, scientists and engineers can now work towards enhancing the detachment of #bubbles. Besides improving the overall efficiency of water electrolysis, this work can also be used in other systems where gas bubbles are formed, such as in #catalysis.

#ASAPpaper of the day: "Mind the Gap: The Role of Mass Transfer in Shaped Nanoporous Adsorbents for Carbon Dioxide Capture" Chemistry and engineering are too often researched as two separate entities. However, they are inseparable at every level, from fundamental principles to practical applications. One of the best examples of this is mass transport. It is equally important to understand whether your small-scale beaker synthesis suffers from mass transport limitations as it is for an industrial adsorption process. In this perspective published in JACS, mass transfer in solid CO2 adsorbents is discussed. If you want to understand your maximum adsorption rate, this is where you need to focus.
