Abstract
This project aims to deepen our understanding of solid-liquid interfaces, which are critical components in next-generation batteries, supercapacitors, and various electrochemical systems. By integrating advanced dielectric techniques such as broadband electrochemical impedance spectroscopy and nonlinear permittivity measurements with optical methods such as Raman spectroscopy and surface plasmon resonance, we will develop a comprehensive platform to probe interfacial phenomena. Our approach combines multiphysics and electrochemical modeling with controlled experimental manipulations, such as bias voltage and adjustable liquid film thickness, to resolve key microstructural and macroscopic parameters of the studied interface. The outcomes will be robust analytical models and experimental tools to bridge theory and practice, bringing the potential to ultimately enhance device performance and reliability.
