electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). An essential part of a battery. It can consist of a variety of materials depending on the type of battery.
The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity.
