Abstract:

Classical electrochemical principles have revolutionized battery  technology and enabled a new era of electronic devices since over 200  years, and after such a long period of time, current battery  technology cannot keep up with increasing power demand. Moreover,  overtaxing batteries via rapid discharge and charge can lead to  performance degradation or even catastrophic failure (fire or  explosion). There remain unknowns regarding microscopic  electron-transfer and ionic transport phenomena through interfaces,  especially electrode-electrolyte interfaces. Lack of precise control  of these microscopic processes poses significant performance, safety,  and fast charging limitations with uncontrollable features such as  high internal resistance, slow ion diffusion, lithium plating,  dendritic growth, hot spot formations, complex coupling, etc.

In this session, I will explain novel battery manufacturing techniques  that will overcome traditional disadvantages in battery technology  such as safety and energy density. New separator and electrode  technologies, as well as an operando technique to determine lithium  intercalation, will be highlighted. I’ll also cover quantum electron  engineering, which is a whole new approach to physics and chemistry  that can be used to rethink old battery technology and push it beyond  theoretical boundaries.

At the end of the talk, I will also discuss some of our other recent  works, such as wearable sensors, AI-assisted sensing, battery-free  information via backscattering, and solar cells.

Short Bio:

Dr. Onur Ergen holds MS, MA, and Ph.D. degrees, in Electrical  Engineering and Physics, all from the University of California  Berkeley. He recently joined the faculty of Istanbul Technical  University where he is currently an assistant professor of Electrical  and Electronics Engineering. He is developing future energy devices  and AI algorithms, which are applicable for smart grid, healthcare,  and new energy concepts. He is also the Senior Technologist at Ambeent  Inc, developing next-generation AI algorithms for 5G platforms.  Previously, Onur worked on developing new semiconductor technologies  at Intel Corp.; was responsible for developing automated systems and  AI interfaces at Apple Inc.; and worked on R&D research and  development activities at Solo Power Inc. He has developed various new  concepts and device architectures from wearable electronics to  lithium-ion batteries, etc. Onur has a strong academic foundation in  energy and novel device architectures with over 25 publications and 12  patents. Dr. Ergen has received various awards including TÜBA, and the  European Research Council (ERC). His ERC research titled QUEEN,  quantum super-exchange energy storage platform leverages quantum  electron engineering to introduce a whole new approach to physics and  chemistry to redesign traditional battery technology and move it  beyond existing theoretical limits.
