“…ESPTs utilize local physical or electrochemical interactions between a small probe (or tip) and the sample (or substrate) enabling micro-to nanoscale investigations of the changes in these properties. For further details regarding in-depth working principles of these ESPTs, we direct readers to additional literature on EC-AFM (14), SECM (13,16), SECCM (17)(18)(19), and SICM (20,21)…”

“…While resolution could be improved by using smaller tip sizes, the fabrication of nanometer-sized electrodes often requires high skill and specialized equipment (100, 101 morphology and electrochemical properties from the same/similar sample. In this regard, SICM could be employed for measuring topography since it has a better resolution than SECM, being limited only by the diameter of the pipette and the distance to the substrate (21). Additionally, its operation does not require a redox mediator.…”

Developing a deeper understanding of dynamic chemical, electronic, and morphological changes at interfaces is key to solving practical issues in electrochemical energy storage systems (EESSs). To unravel this complexity, an assortment of tools with distinct capabilities and spatiotemporal resolutions have been used to creatively visualize interfacial processes as they occur. This review highlights how electrochemical scanning probe techniques (ESPTs) such as electrochemical atomic force microscopy, scanning electrochemical microscopy, scanning ion conductance microscopy, and scanning electrochemical cell microscopy are uniquely positioned to address these challenges in EESSs. We describe the operating principles of ESPTs, focusing on the inspection of interfacial structure and chemical processes involved in Li-ion batteries and beyond. We discuss current examples, performance limitations, and complementary ESPTs. Finally, we discuss prospects for imaging improvements and deep learning for automation. We foresee that ESPTs will play an enabling role in advancing EESSs as we transition to renewable energies. Expected final online publication date for the Annual Review of Analytical Chemistry, Volume 16 is June 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
