This is an authored directed relation from the source endpoint to the target endpoint.
An electrode establishes an interface where electronic and ionic charge, adsorption, solvent structure, reaction, and transport are coupled.
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

Electrodes connect electron conduction to interfacial charge transfer or capacitive response.
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.
wp-chem-electrochemistryopenstax-chemistry-2eiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
An electrode in contact with an electrolyte develops a potential- and composition-dependent double layer involving electronic charge, solvent orientation, diffuse ions, and possible specific adsorption.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-chem-electrochemistryopenstax-chemistry-2eiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
An electrode interface has charge-transfer kinetics only for a specified redox couple, electrolyte, potential reference, surface state, and transport condition; the electrode material alone does not determine a universal rate.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.

An operating electrode has an overpotential relative to a defined equilibrium potential; charge transfer, mass transport, resistance, bubbles, area, and reference placement can all contribute.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
