IMSE Seminar with Hui Xiong on Defect and Interface/Interphase Engineering for Rechargeable Metal Ion Batteries

Rechargeable batteries are promising energy storage technologies to provide high energy and high power for applications such as electric vehicles and electric grids integrating intermittent renewable energy resources. Recent studies have shown enhanced electrochemical charge storage in electrodes that contain intentional structural defects (e.g., vacancies and interstitials) or with tailored interface/interphase. In this seminar, I will discuss recent works at the Electrochemical Energy Materials Laboratory at Boise State including engineering defects in electrode materials through ion irradiation, and operando electrochemical cycling, as well as interface engineering in composite electrodes and studies of solid electrolyte interphases for metal ion batteries (e.g., Li ion and Na ion batteries). We hope to provide some perspectives regarding new pathways to design and engineering defects and interfaces in electrode materials with enhanced energy/power for rechargeable batteries. Dr. Hui (Claire) Xiong is a Professor in the Micron School of Materials Science and Engineering at Boise State University. Dr. Xiong received her BE degree in Applied Chemistry, MS degree in Solid State Chemistry from East China University of Science and Technology. She received her Ph.D. in Electroanalytical Chemistry from the University of Pittsburgh in 2007. Between 2008 and 2012, she conducted postdoctoral work at Harvard University and Argonne National Laboratory where her research involved electrochemical characterization of microfabricated cathode materials for micro-solid oxide fuel cells and the development of novel nanostructured electrode materials for Li-ion and Na-ion batteries. She joined Boise State University in 2012. Dr. Xiong received NSF CAREER Award in 2015, is the Fellow of the Royal Society of Chemistry, Fellow of the American Ceramic Society, a Scialog Fellow, and the Fellow of the Center for Advanced Energy Studies. Dr Xiong’s research focuses on design and development of nanoarchitectured and defect-driven electrode materials for Li-ion and Na-ion batteries and beyond, ion irradiation effects on electroceramics, mechanistic insights on electrolyte degradation, and in situ and operando characterizations of energy materials.

Faculty, students, and the general public are invited.
