Mekanisk afhøring af batterisikkerhed

Lithium-ion-batterier er i øjeblikket udbredt på tværs af bærbar elektronik og elektriske køretøjer og er på fremmarch for nye teknologisegmenter, herunder netlagring, langdistance-/heavy-duty-transport og elektrisk luftfart. Dette er imidlertid baseret på sikker drift af lithium-ion-batterier under operationelle ekstremer, herunder ekstrem hurtig opladning og uheldige misbrugsscenarier, der kan føre til termiske løbske katastrofer. I denne henseende er det bydende nødvendigt at forstå de mekanistiske implikationer af underliggende termo-elektrokemiske interaktioner i skalahierarki i de resulterende termiske sikkerhedskonsekvenser. Denne præsentation vil give et overblik over mekanismedrevet sikkerhedsfysik og analyse til afgrænsning af termiske stabilitetssignaturer i lithium-ion batterikemi og videre.

Partha P Mukherjee is a professor of mechanical engineering and university faculty scholar at Purdue University. His prior appointments include assistant professor and Morris E Foster faculty fellow of mechanical engineering at Texas A&M University (2012­–2017), staff scientist at Oak Ridge National Laboratory (2009­–2011), director’s research fellow at Los Alamos National Laboratory (2008­–2009), and engineer at Fluent India (subsidiary of Fluent Inc., currently Ansys Inc., 1999–2003). He received his PhD in mechanical engineering from The Pennsylvania State University in 2007. His awards include Scialog Fellows’ recognition for advanced energy storage, University Faculty Scholar and Faculty Excellence for Early Career Research awards from Purdue University, The Minerals, Metals & Materials Society Young Leaders Award, to name a few. His research interests are focused on mesoscale physics and stochastics of transport, chemistry and materials interactions, including an emphasis in the broad spectrum of energy storage and conversion.
