Electrochemical Stress Phenomena in Surface Interactions

Electrochemical stress phenomena arise from the intimate coupling of charge transfer at solid–electrolyte or solid–vapour interfaces with the mechanical response of the material’s surface. Redistribution of ions and electrons induces local surface stresses that manifest as tensile or compressive strains. These deformations can alter adsorption enthalpies and reaction kinetics, while surface stress itself modulates interfacial potentials and electrosorption behaviour. Such bidirectional feedback is central to the performance of electrocatalysts, the stability of energy‐storage electrodes and the durability of corrosion‐resistant coatings. Advances in in situ characterisation methods—such as cantilever curvature measurements, dynamic stress analysis and electrochemical impedance spectroscopy—have provided real‐time insights into how strain influences double‐layer charging, film growth during electrodeposition and the formation of surface vacancies. This knowledge enables the rational design of interfaces with bespoke mechanical and electrochemical properties, bridging materials science, surface chemistry and applied electrochemistry.
