Abstract

Forthcoming ubiquitous electronics era, which will find widespread use of electric vehicles, grid-scale stationary energy storage systems, and portable flexible/wearable electronics, is in relentless pursuit of advanced Li batteries. Li batteries are generally comprised of inorganic- or metal-based compounds, carbonaceous substances, and petroleum-derived hydrocarbon chemicals. These traditional synthetic materials, however, may have difficulties fulfilling the ever-increasing requirements of rechargeable power sources. Recently, nanocellulose has garnered considerable attention as an exceptional one-dimensional (1D) element due to its natural abundance, environmental friendliness, recyclability, structural uniqueness, facile modification, and dimensional stability. In this talk, I’ll explore recent advances and development direction of nanocellulose as a new material route that can push the boundaries of Li battery electrodes based on synthetic materials. The structural uniqueness (characterized by the nanoscale dimension, 1D directionality, lightweight, flexibility, and high crystallinity) and chemical functionalities of nanocellulose enable exceptional performance improvements in the electrodes of Li-ion batteries (LIBs) and post-LIBs. We envision that the nanocellulose brings unprecedented performance benefits to the LIBs and post-LIBs, which lie beyond those achievable with conventional synthetic materials

About the Speaker

Sang-Young Lee is a Hwalchun distinguished professor of Department of Chemical and Biomolecular Engineering at Yonsei University, Korea. He received BA in Chemical Engineering from Seoul National University in 1991, MS, and PhD in Chemical Engineering from KAIST in 1993 and 1997. He served as a postdoctoral fellow at Max-Planck Institute for Polymer Research from 2001 to 2002. Before joining UNIST, he worked at Batteries R&D, LG Chem as a principal research scientist who led the development of ceramic-coated separators (SRS®). He is a fellow of both the Korean Academy of Science and Technology and the National Academy of Engineering of Korea. He is the director of Yonsei Battery Research Centre and serves as the editor of Journal of Power Sources (Elsevier). His research interests include the high-mass-loading electrodes, organic material-based solid-state batteries, cellulose-based paper batteries, and flexible/wearable power sources.
