N2 - Since their introduction, Lithium-ion batteries (LIBs) have revolutionized the world of portable electronics and sustainable mobility[1]. LIBs currently play a pivotal role across several sectors, thanks to their long cycle life, fast-charging capabilities, unmatched energy densities, and a broad operating temperature range. Given the increasing demand of this technology[2,3], challenges including safety concerns, limited resource availability, and environmental impact need to be addressed. To improve the next-generation systems, understanding the cell degradation pathways is crucial. However, the complexity of these systems, comprising organic and inorganic compounds in various aggregation states, poses challenges to studying the involved degradation processes. Inspired by geochemical studies, which displayed lithium isotope fractionation in dynamic natural systems, attributed to the high mass difference (ca. 16%) between the heavier (ca. 7Li, 92.5%) and the lighter isotope (ca. 6Li, 7.5%)[4], this work investigates weather a difference in Li isotope distribution within battery components can serve as a diagnostic and/or predictive tool for determining the remaining useful lifetime (RUL) of batteries[5]. Initial observations of Li isotope variation during battery aging were made in commercial cells. This was followed by systematic studies based on lab-scale coin-cells fabricated with different cathode materials[6]. While multicollector ICP-MS (MC-ICP-MS) investigation of each cell component enabled quantification of Li isotope fractionation in new and aged batteries with a 0.2 ‰ precision, glow discharge mass spectrometric (GD-MS) analysis provided spatially resolved information on Li isotopic distribution variation upon cells aging. The results display a meaningful correlation between post-mortem chemical analysis and electrochemical cells’ performance, highlighting the potential of Li isotope distribution in the electrodes as both a benchmark for battery degradation and a valuable indicator for assessing battery RUL.

Aufgrund ihrer toxikologischen Relevanz hat die Europäische Union im Jahr 2022 erstmals Grenzwerte für diese Alkaloide in Lebensmitteln eingeführt. Eine zuverlässige Quantifizierung ist essenziell für die Überwachung der Lebensmittelsicherheit. Allerdings stellte der bisherige Mangel an stabilen isotopenmarkierten (SIL - stable isotopically labeled) Standards eine wesentliche Herausforderung für die Entwicklung präziser Analysemethoden mittels HPLC-MS/MS dar. Um diese Lücke zu schließen, wurden erstmals alle zwölf prioritären Mutterkornalkaloide über einen einheitlichen Semisyntheseansatz als 13CD3-markierte Analoga synthetisiert und als interne Standards für die massenspektrometrische Analyse eingesetzt. Die Quantifizierung erfolgte mittels HPLC-MS/MS in verschiedenen Lebensmittelmatrizes, darunter Brot, Roggen- und Weizenmehl sowie Kleie. Zur Evaluierung der SIL-Standards wurden etablierte Methoden wie externe Kalibrierung und Standardaddition herangezogen. Die Studienergebnisse zeigen, dass der Einsatz von SIL-Standards die Genauigkeit und Präzision der Mutterkornalkaloid-Quantifizierung signifikant verbessert. Dies ist insbesondere auf die Korrektur von Matrixeffekten, Extraktions- und Signalschwankungen während der massenspektrometrischen Analyse zurückzuführen. Die neu synthetisierten 13CD3 markierten Mutterkornalkaloide stellen daher ein wertvolles Werkzeug zur Verbesserung der Lebensmittelsicherheit dar, da sie zuverlässigere und reproduzierbare Messergebnisse ermöglichen. Darüber hinaus leisten diese Ergebnisse einen wichtigen Beitrag zur Weiterentwicklung analytischer Methoden zur Überwachung von Mutterkornalkaloiden und damit zur Sicherstellung der Lebensmittelqualität.
