An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit. Electrodes are essential parts of batteries that can consist of a variety of materials depending on the type of battery.
Electrodes used in shielded metal arc welding
Various disposable batteries: two 9-volt, two "AAA", two "AA", and one each of "C", "D", a cordless phone battery, a camcorder battery, a 2-meter handheld ham radio battery, and a button battery.
Rechargeable Batteries
A typical flow battery consists of two tanks of liquids which are pumped past a membrane held between two electrodes.
