Electrode potential describes the tendency of an electrode interface to participate in oxidation or reduction under specified conditions. It reflects the energetics of charge transfer and depends on the electrode material, chemical species, activities, temperature, and interface state. Because an absolute single-electrode potential cannot be measured independently in a conventional experiment, practical values are measured relative to a reference electrode.

Oxidation and reduction are paired electron-transfer processes at the heart of electrochemistry. Oxidation means loss of electrons, while reduction means gain of electrons. In an electrochemical cell, the two processes occur at different electrode interfaces and are linked by electron flow through the external circuit and ion transport through the electrolyte.

An electrolyte is a substance or medium that contains mobile ions and conducts ionic current. In electrochemical research, it completes the ionic pathway between electrodes and influences charge balance, reaction kinetics, selectivity, and stability. Electrolytes may be aqueous solutions, non-aqueous liquids, polymer gels, molten salts, or solid ion conductors.
