Dr. Taeho Yoon joined NREL in 2017 as a postdoctoral researcher. He received his Ph.D. from Seoul National University in South Korea, under the direction of Prof. Seung M. Oh, and then moved to Prof. Brett L. Lucht’s group at the University of Rhode Island as a postdoctoral fellow. He developed his expertise in electrochemistry and lithium-ion batteries (failure mechanisms and surface reactions) during his Ph.D., and he continued his research with Prof. Lucht on understanding and modifying the surface film (solid electrolyte interphase, SEI) deposited on the Si electrode for lithium-ion batteries. His current research focuses on developing: 1) a fundamental understanding of the role of SEI and binder in Si electrodes, and 2) advanced methods to improve the electrochemical performance of lithium-ion batteries.
- Fundamental understanding of electrochemical energy storage systems
- Surface reactions on both positive and negative electrodes for lithium-ion batteries
- Solvate structures of electrolyte and their effects on electrochemical reactions
