Karin Kleiner is an electrochemist with more than seven years of experience in the field of materials characterisation (batteries and fuel cells). In 2011 she started her PhD as an employee of the BMW group Munich investigating degradation mechanisms in commercial Li-Ion batteries from automotive field tests. She received her PhD from the Karlsruhe Institute of Technology (KIT) in 2014 and received a GDCh career grant of the Electrochemistry Section for this work. In 2015 she joined the Department of Technical Electrochemistry at the Technical University of Munich where she studied high energy cathode materials for future applications in lithium-ion batteries followed by 2 years at the Diamond Light Source (UK’s synchrotron facility) where she developed operando techniques to investigate energy storage devices. Now she is head of a young investigator group at the battery research center MEET at the University of Münster, where she is looking into the physical origin of energy density limitations of state of the art and future battery materials. She has been a Lecturer at the Joint European Summer School on Fuel Cell, Electrolyser, and Battery Technologies since 2014.
