• A Spreadable Interlayer Could Make Solid State Batteries More Stable

    The interlayer makes the battery cell much more stable, and therefore able to withstand much higher current density. It is also very easy to apply the soft mass onto the lithium metal anode in the battery - like speading butter on a sandwich.​​​​​​​ ​Illustration: Yen Strandqvist

    Solid state batteries are of great interest to the electric vehicle industry. Scientists at Chalmers University of Technology, Sweden, and Xi’an Jiaotong University, China now present a new way of taking this promising concept closer to large-scale application. An interlayer, made of a spreadable, ‘butter-like’ material helps improve the current density tenfold, while also increasing performance and safety.

  • Highly Promising Solid Electrolytes for High-Performance Lithium-Ion Batteries

    High-performance, long-lasting energy storage devices are crucially important for many future-oriented technologies: e.g. for electromobility, for mobile end devices such as tablets and smartphones as well as for the efficient use of energy from renewable sources. Dr. Daniel Mutter from the Fraunhofer IWM was able to clarify what the chemical composition of solid ceramic electrolytes should be in order to ensure good performance in lithium-ion batteries. The research was published in the Journal of Applied Physics. Such solid electrolytes are more environmentally friendly than traditional liquid electrolytes and could make lithium-ion batteries significantly safer and more efficient.

  • Neuer Katalysator für die Wasserstoffproduktion

    Das Mineral Pentlandit ist ein potenzieller neuer Katalysator für die Wasserstoffproduktion. Forscher beschreiben in der Zeitschrift „Nature Communications“, dass es genauso effizient arbeitet wie heute übliche Platinelektroden. Im Gegensatz zu Platin ist Pentlandit günstig und kommt häufig auf der Erde vor. Ein Team um Dr. Ulf-Peter Apfel und Prof. Dr. Wolfgang Schuhmann von der Ruhr-Universität Bochum beschreibt die Ergebnisse gemeinsam mit Kollegen vom Max-Planck-Institut für Kohlenforschung in Mülheim an der Ruhr und der Technischen Universität in Bratislava.
