Single-Particle Measurements: A Powerful Method for Investigating Electrochemical Reactions.

The relationship between interface structure (e. g., the facet of the solid phase and the configuration of solvation) and the reactivity of the corresponding electrode is a critical issue in electrochemistry. Compared to macroscopic electrode measurements, electrochemical methods established on the single-particle scale have advantages in establishing the structure-property relationship. In recent years, great achievements have been made in electrochemical energy storage and electrocatalysis that allow the evolution and kinetics of electrodes to be understood by employing single-particle measurements. This concept aims to provide an overview of the update of single-particle measurements in related electrochemical processes. Furthermore, the challenges and prospects for the development and application of single-particle measurements are also discussed.
