报告摘要：
Electrification-driven processes are essential to achieving sustainable energy and a cleaner environment, including electrochemical conversion and environmental monitoring. Designing these processes requires a deep understanding of the electrode-electrolyte interface, where molecular interactions dictate energy and power density, as well as device lifetime. In this seminar, I will describe how we understand and design electrochemical reactions, charge transfer, and electrokinetics at the electrode-electrolyte interface in Li-ion batteries, hydrogen fuel cells, and environmental biosensing. First, we developed in situ Fourier-transform infrared spectroscopy (FTIR) with Li-ion battery cycling capabilities to elucidate the formation of the electrode-electrolyte interface layer on Ni-rich positive electrodes. The dehydrogenation pathway was identified and provides design principles for stabilizing battery cycling. Next, I discuss the ion intercalation mechanism across the interface in Li-ion batteries. We developed a charge-compensated electrochemical method to demonstrate coupled ion-electron transfer, which reveals a kinetic limitation to the maximum usable capacity. We extend these approaches to hydrogen-fuel-cell reactions, where I demonstrate mechanisms and strategies by which interfacial hydrogen bonds modify electrocatalytic kinetics. Lastly, beyond electrochemical energy conversion, we apply plasmon-enhanced Raman scattering and machine learning for biological interfaces, enabling the design of an integrated electrokinetic system for label-free bacterial identification in wastewater. These studies offer insights for the rational design of materials for next-generation batteries, electrocatalysis, and biosensing systems with improved efficiency and lifetime.
