Anna Stefanopoulou, William Clay Ford Professor of Technology in the U-M Department of Mechanical Engineering, sat down recently with Let’s Talk!, a podcast series hosted by the Electrochemical Safety Research Institute (ESRI) at UL Research Institutes. The series aims to hear the views and learn from scientists, researchers, and subject matter experts about specific areas of interest in the energy storage sector and to share the knowledge with their collaborators.
Dr. Stefanopoulou talked about her group’s work on battery management and control, physics-based modeling of lithium-ion battery degradation, and the field’s challenges and new opportunities. She also spoke on the detection of faults in lithium-ion batteries in field use and how reliable detection of faults can help to mitigate the outcome of a potential thermal runaway event.
“We’re trying to estimate or detect degradation and understand degradation, not just the cell length capacity and cell resistance…In my lab we try to actually understand the capacity of the anode and the cathode…and ideally the resistance that occurs because of anode reactions and cathode reactions. We believe that is important to resolve as our batteries age because that’s what is gonna give us a lot more information regarding degradation that could lead to failure and could lead to, eventually, safety issues,” said Dr. Stefanopoulou.
