Prof. Ya-Ting T. Liao, Associate Professor, Mechanical and Aerospace Engineering, Case Western Reserve University, talks about the different fire safety hazards and risks associated with lithium-ion batteries.

Brett A. Perlman serves as the CEO of the Center for Houston’s Future, a nonprofit organization working to address matters of the highest importance to the long-term future of the greater Houston region. In this podcast, he shares his insights about green hydrogen technology from a global perspective. 

Dr. Ahmad Pesaran from National Renewable Energy Laboratory (NREL) describes the Lithium-ion Battery Supply Chain Database that was developed to include North American companies involved in all aspects of the lithium-ion battery supply chain. 

Penni Dalton, Former ISS EPS Battery Subsystem Manager​, NASA Glenn Research Center​, discusses the characteristics of Nickel-Hydrogen batteries in the Electric Power System (EPS) onboard the International Space Station (ISS), their replacement process for lithium-ion batteries, and the safety aspects of both battery chemistries. 

Kevin Wujcik, Chief Technology Officer at Blue Current, talks to our host regarding solid state batteries.

Professor Anna Stefanopoulou from University of Michigan talks to us about her group’s work on battery management and control, physics-based modeling of lithium-ion battery degradation, and the challenges and new opportunities in the field. She also talks about 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. 

Moreover, Prof. Stefanopoulou highlights how engineers working with battery systems are constantly working to improve the safety of the systems.  

Lithium-ion batteries hold enormous potential for a fossil-free future. But in order for that potential to be reached, they need to be used responsibly and recycled safely. Solving environmental and safety risks associated with li-ion batteries will require changes in policy and business practices. But with so many li-ion powered technologies in the hands of consumers, individual awareness and behavior change regarding safe and responsible recycling can make significant impacts too.  

Consulting agency DoGoodery is teaming up with the Electrochemical Safety Research Institutes (ESRI) of UL Research Institutes, to launch a national campaign to educate and encourage consumers to safely and sustainably use and recycle li-ion batteries. In this episode, they discuss the goals of the campaign, strategies they’re using to authentically engage audiences and inspire action, and how this kind of campaign can move people from all walks of life to further UL’s mission in the choices they make every day.

Dr. Jason Ostanek, an assistant professor at Purdue University, highlights the role of modeling and simulation in the safety of lithium-ion batteries. He summarizes challenges associated with developing a comprehensive thermal runaway model and possible ways to overcome these challenges. Also, he sheds light on multiple strategies to accelerate battery failure modeling and simulation and shares his perspective on scaling these models to larger systems.
