Interfacial engineering for advanced electrochemical devices
Interfacial engineering for advanced electrochemical devices Hee-Tak Kim Department of Chemical and Biomolecular Engineering, KAIST In recent decades, electrochemical devices, including batteries, fuel cells, and electrolysis, have made significant strides. However, their progress is often hindered by various interfacial problems that are challenging to identify and address. Space charges, double layer charges, charge transfer, and mass transport intricately influence the performance and durability of electrochemical devices. The complexity of interfaces and the limited means available for characterizing interface structures often result in unresolved or overlooked interfacial issues. This seminar emphasizes the importance of interfacial engineering and provides a fundamental understanding of electrode/electrode, electrolyte/electrolyte, and electrode/electrolyte interfaces. Based on this understanding, case studies are presented to demonstrate how to leverage this knowledge and control interface structures for designing advanced electrochemical devices....
