Do Y. Yoon
Adjunct Professor, Chemical Engineering
BioDo Y. Yoon is Adjunct Professor of Chemical Engineering at Stanford University since 2012. He obtained his B.S. in Chemical Engineering from Seoul National University, Korea (1969), and earned his Ph.D. in Polymer Science and Engineering from University of Massachusetts Amherst, working with Richard S. Stein (1973). He did his postdoctoral study with Paul J. Flory in Chemistry Department of Stanford University (1973-1975). He then worked in IBM Research Laboratory in San Jose, California as Research Staff Member and Manager of Polymer Physics Group (1975-1999). From 1999 to 2012, he was Professor of Chemistry at Seoul National University, Korea, and served as the Korean spokesperson of the Germany-Korea International Research Training Group on “Self-organized Materials for Optoelectronics” (2006-2012) and also as member of science advisory board of LG Chem (2000-2006). He published about 260 research papers (h-index: 73), was elected a fellow of American Physical Society (1985), and received Humboldt Research Award by the Alexander von Humboldt Foundation of Germany (1999) and Academic Achievements Award from the Alumni Association of Seoul National University (2017). His research areas included molecular conformations & dynamics, semicrystalline molecular morphology, liquid crystalline state, surface and thin film characteristics of polymers, and structure-property relationships of polymers for information technology, organic electronics, and clean energy. He is a co-editor of "Selected Works of Paul J. Flory" and a co-author of "Paul John Flory: A Life of Science and Friends."

Current Research and Scholarly InterestsLong charging times of lithium-ion batteries (LIBs) is a major bottleneck in the widespread deployment of electric vehicles (EVs). There is a global push to enable extreme fast charging (XFC) of EV batteries to reduce their charging times to 10-15 minutes. But existing LIBs cannot achieve this goal without significantly reducing battery performance. This is mainly attributed to a phenomenon, known as “Li plating,” as the battery is charged fast. In this thesis, I use neutron and X-ray-based imaging to visualize the battery electrode to investigate Li plating at elevated charging rates.
