anodes
Oxidation reaction sites
Anodes are electrodes where current flows into a device—the positive terminal of a battery during discharge, or the electrode where oxidation occurs in electrolysis.
In electronics, anodes attract electrons: The anode of a vacuum tube collects electrons from the cathode.
Sacrificial anodes are chunks of reactive metal attached to ships or pipelines, corroding preferentially to protect the underlying structure.
