Abstract
Electrochemical processes underpin many modern technologies (e.g., batteries, fuel cells, and corrosion protection systems), and because these processes are often controlled by interactions that occur at the nanoscale, gaining insight into nanoscale electrochemical behavior is essential to advancing these technologies. Nanoscale electrochemical imaging probes measure electrochemical activity with nanoscale spatial resolution and have enabled researchers to gain new insights into diverse experimental systems. However, limitations remain, including a lack of methods for direct quantitative interpretation, the influence of atmospheric conditions on experimental reproducibility and stability, and a knowledge barrier resulting from limited accessible resources, all of which continue to restrict more widespread adoption. This dissertation addresses these challenges and advances nanoscale electrochemical imaging, specifically scanning electrochemical cell microscopy (SECCM), by developing tools, methodologies, and associated theory for SECCM through experimental and numerical modeling methods. This work enables more accessible, more functional, more informative, and faster measurements. Transparent, step-by-step workflows, shared designs, controlled-environment experiments, and species-switching capabilities for SECCM are provided, enabling quantitative studies of nanoscale electrochemical phenomena. Together, these contributions enhance SECCM as a high-throughput platform for nanoscale electrochemical studies with real-world applications, while promoting open science and broader adoption across laboratories.
