Abstract

This project aims the study of abiotic systems, specifically energy conversion and storage devices, to understand how electrified surfaces behave during heterogeneous charge transfer reactions, which are essential for these devices. The project will examine the impact of localized interfacial properties, such as morphology and composition, on device performance, especially with solid electrolyte interface (SEI). Using space-resolved techniques, specifically Scanning Electrochemical Cell Microscopy (SECCM) and Interference Reflection Microscopy (IRM), the research will explore the behavior of single nanoscale entities, also making use of simulations to correlate observed changes with each technique. Additionally, the project aims to prove a more limited but still capable alternative to expensive X-ray tomography for analyzing battery materials.
