A system of electrodes and ion-conducting phases arranged to convert chemical and electrical work or to drive chemical change electrically.

This is an authored directed relation from the source endpoint to the target endpoint.
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 electrolyte closes the internal ionic current path and maintains electroneutral transport between electrode regions.
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.

Electrochemical cells require an ion-conducting medium and electronic paths while controlling mixing and junction potentials.
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.

The pile made chemically generated current reproducible and enabled decomposition, isolation, and quantitative study before modern interfacial theory.
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.

This is an authored directed relation from the source endpoint to the target endpoint.
An electrolytic cell consumes electrical work to force a net chemical transformation.
The target is a member or subtype of the broader source class.
wp-chem-electrochemistryopenstax-chemistry-2eiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
A galvanic cell operates with a spontaneous cell reaction under its discharge conditions.
The target is a member or subtype of the broader source class.
wp-chem-electrochemistryopenstax-chemistry-2eiupac-gold-bookThis is an authored directed relation from the source endpoint to the target endpoint.
An electrochemical cell reaction has a Gibbs-energy change related reversibly to cell potential under stated temperature, pressure, activities, electron count, and sign conventions; losses reduce operating voltage.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
