The electrochemical reaction takes place at the electrochemical interface and at the junction between the electrode and the electrolyte. The efficiency of energy conversion and energy storage is almost entirely determined by the rate of transfer of interfacial charges based on basic electrochemistry and the electrochemical interfacial properties that control the various types of interactions. However, the importance of the electrochemical interface, which is usually the electrode/electrolyte interface, is often neglected, and most studies focus the electrode itself or the electrolyte as a separate field, hindering its application to electrochemical energy conversion and storage devices. Given that overall electrochemical performance is determined by how understand and design the interface, it is important to understand and design an electrochemical interface as the basic unit of electrochemistry. Here I describe the dynamic electrochemical interface in the oxygen evolution reaction. Unlike the conventional 'static' interface, the properties of the 'dynamic' interface are determined by the continuous interaction between electrolyte and electrode, and based on this, it opens the possibility of a new system that can overcome the existing thermodynamic limitation on electrode.
