Join us for a talk with Steen B. Schougaard that will focus on ion transport and why it is one of the major challenges in high power operation of Li-ion batteries.
The study of ion transport requires in situ or ideally operando measurement, since kinetics drive the formation of concentration gradients, which relax rapidly once the circuit is broken. In turn this has led us and others to the development of new analytical methods to characterise ionic transport across scales: from the single active particle, over the electrode up to the full cell scale. The talk will close with an example of how recycled materials can be used to improve electrode performance, in part due to improved ionic conduction.
About the speaker:
Steen B. Schougaard, is the former Chair of the Chemistry Department and Professor of Inorganic Chemistry at the Université du Québec à Montréal (UQAM). A native of Denmark, he received his Ph.D. from the University of Texas at Austin, followed by a Postdoctoral Fellowship with Nobel laureate Prof. J. B. Goodenough and a temporary researcher position at RISØ Danish national laboratory, wherefrom he was recruited to UQAM. At the UQAM, he has developed in close collaboration with industry a research program around lithium-ion batteries, which include atomistic to mesoscale modeling, conducting polymer based electrodes, scanning electrochemical probes and advanced in situ characterization techniques requiring synchrotron radiation.
