Correlative co-located electrochemical multi-microscopy

Correlative co-located electrochemical multi-microscopy is transforming our understanding of property-function relationships in electrode materials. By coupling scanning electrochemical cell microscopy (SECCM) with complementary characterization techniques applied to identical locations of a surface, we can now unravel the intricate interplay between various physicochemical properties of electrode materials and interfaces and their impact on electrochemical phenomena, with high spatial resolution. This review explores recent advances in this correlative approach to showcase how it can reveal major new insights into the activity of materials and interfaces. Applications span diverse electrochemical fields, including energy conversion and storage, sensing, and corrosion science. We also envision future developments that will open up new possibilities for rational materials design, accelerated mechanistic understanding, and automated materials discovery.
