Location: TUM-IAS Auditorium (ground floor), Lichtenbergstraße 2 a, 85748 Garching
Speaker: Dr. Sascha Nowak, University of Münster, MEET Battery Research Center, Institute of Physical Chemistry.

Sascha Nowak studied chemistry at the University of Münster and got his PhD in Analytical Chemistry. After his doctorate, he joined the working group of Prof. Winter at the MEET Battery Research Center in 2009 as a postdoctoral researcher where he established the analytical department. From 2010-12 he was the head of the competence areas Analytics and Recycling and since 2012 he holds a position as scientific staff at the MEET Battery Research Center at Münster University as the head of the division Analytics and Environment, which mainly focuses on electrolyte aging, transition metal migration and surface investigations, recycling and 2nd life as well as toxicological investigations.
Abstract:
Since modern batteries contain large numbers of components, a variety of analytical methods is required to analyze the characteristics and quantities of aged cells. The aim is to understand both calendaric and cyclic aging is a very precise way. Then, strategies for customization, thus, both prevention of unfavorable reactions and promotion of beneficial effects are the underlying objective. One focus of this division at MEET is on the aging analysis of the electrolytes. This includes not only the examination of the decomposition of electrolytes and the migration of active material into the electrolyte, but also investigations on the formation and the properties of potentially toxic substances.
The talk will give two examples, one from the area of electrolyte degradation and one from the field of transition metal dissolution and deposition on the anode surface.
Admission is free. No registration required.
