Thomas Lord Department of Mechanical Engineering Spring 2024 Seminar Series welcomes Neil Dasgupta (Univ. of Michigan) to give the MEMS Seminar lecture on "Electo-Chemo-Mechanical Phenomena in Solid State Batteries."
ABSTRACT: Solid-state batteries have seen a dramatic increase in research in recent years because of their ability to address safety challenges associated with flammable liquid electrolytes, and the potential to enable high-energy-density electrodes including Li metal anodes. However, the formation of solid-solid interfaces in a battery poses unique challenges compared to solid-liquid interfaces, many of which center around the unique coupling of mechanical stresses and strains to thermodynamic, kinetic, and transport phenomena. This requires new methods to study the fundamental behavior of solid-state electrochemical interfaces, and understand their dynamic evolution during cycling.
BIO: NEIL DASGUPTA is an Associate Professor in the Departments of Mechanical Engineering and Materials Science & Engineering at the University of Michigan. He is the Deputy Director of the U.S. Department of Energy, Energy Frontier Research Center (EFRC) MUSIC: Mechano-Chemical Understanding of Solid-Ion Conductors. He earned his Ph.D. from Stanford University in 2011. Prior to joining University of Michigan in 2014, he was a postdoctoral fellow at the University of California, Berkeley. He is a recipient of the NSF CAREER award, DARPA Young Faculty Award (YFA), and AFOSR Young Investigator Award (YIP). His research focuses on the intersection of materials chemistry, energy conversion, and manufacturing.
