The forthcoming smart electronics/the Internet of Things (IoT) era drives the relentless pursuit of high-performance power sources with various form factors. From a battery design point of view, conventional rechargeable batteries have suffered from lack of variety in design diversity, thus imposing formidable challenges on their integration into electronic devices. Recently, printed batteries have garnered considerable attention as a crispy power source with exceptional shape diversity and process simplicity, which lie far beyond those achievable with conventional battery technologies. This talk will present a new class of form factor-free, printed power sources which can be monolithically integrated devices, with a particular focus on key-enabling technologies and their potential applications.
Sang-Young Lee is a professor and a head of School of Energy and Chemical Engineering at UNIST, 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. His research interests include printed power sources, flexible/wearable batteries, cellulose-based paper batteries, advanced separator membranes and polymer electrolytes.
ubatt is a new class of solid-state thin-film battery producer that brings unprecedented benefits in cell design, safety, and high-voltage operation.
