MEET PhD Students Honoured at IMLB 2022

The poster “New Approaches to the Analysis of the SEI Formation on Lithium Metal” by MEET PhD student Bastian von Holtum was awarded “Highly Commended Poster” at this year's International Meeting on Lithium Batteries (IMLB) in Sydney, Australia. Co-authors are MEET scientists Maximilian Kubot, Christoph Peschel, Dr Sascha Nowak, Prof. Dr Martin Winter and Dr Simon Wiemers-Meyer.

Composition of Primary SEI in Lithium-based Battery Systems Analysed

The research focuses on a novel accumulation method that enables the analysis of the qualitative and quantitative composition of the primary SEI in lithium-based battery systems. “Until now, such an analysis was only possible with limitations, as the layer is much thinner before cyclisation than after, and substances are therefore only available to a very low extent,” explains Bastian von Holtum, who works in the research division Analytics & Environment at MEET Battery Research Center. Using a novel accumulation method, the research team has succeeded in examining the gas phase, the electrolyte and the solid in detail. “Now any liquid electrolyte can be investigated for its transformation to the primary SEI in lithium-based battery systems,” says von Holtum.

Another award as “Highly Commended Poster” was received by MEET PhD student Iris Dienwiebel.

About IMLB 2022

More than 800 participants from 32 countries attended the IMLB, which took place in Sydney from 26 June to 1 July 2022, and informed themselves about the latest findings in lithium battery research. Around 70 presentations as well as an extensive poster and industrial exhibition provided detailed insights into both basic and applied research.
