Poster Award for MEET Researcher Dr Julia Dressler

For her presentation on the topic “ICP-TOF-MS and HRAM-MS in the Field of Battery Research, Production, and Recycling - from Single-particle Analysis to Molecular Imaging,” MEET researcher Dr Julia Dressler was awarded a poster prize at the “12th Nordic Conference on Plasma Spectrochemistry and Ionization Principles in Mass Spectrometry: From Elements to Molecules” in Loen, Norway. A total of two prizes of equal rank were awarded at the conference, each worth 2,000 Norwegian kroner (approximately 176 euros).

New Analytical Methods for a Better Understanding of Battery Aging

Battery aging is a critical factor in their performance and service life. However, the underlying processes have not yet been fully investigated. In her poster presentation, Dressler highlighted the potential of two modern mass spectrometric analytical methods for studying particulate and molecular processes. High-resolution mass spectrometry (HRAM-MS) is particularly well-suited for investigating changes in the electrolyte at the molecular level. Inductively coupled plasma time-of-flight mass spectrometry (ICP-TOF-MS), on the other hand, allows for the analysis of particles from electrode materials and thus provides valuable information about electrode aging processes. As a proof of concept, Dressler also presented initial results from the analysis of various particles of lithium-nickel-manganese-cobalt oxides, thereby highlighting the great potential of these methods for investigating battery aging processes.

Co-authors of the poster are Alexandros Tsoufios, Nick Fehlings, Dr Sascha Nowak and Dr Simon Wiemers-Meyer, MEET Battery Research Center at the University of Münster as well as Prof. Dr Martin Winter, MEET Battery Research Center and Helmholtz Institute Münster of Forschungszentrums Jülich.
