Why is graphite used for electrodes?

Zhongsheng Carbon27 Sep, 2024News

Electrodes can be made from any conductive material. Depending on the nature of the application, electrodes are typically from graphite. Noble metals like gold, silver or platinum can be used but are very expensive. Copper, titanium and brass are other options, but they are also costly. Graphite is used as an electrode material because it is a good conductor of electricity, is chemically stable, and can withstand high temperatures. It also has a low reactivity and thermal expansion coefficient, making it suitable for electrode use in electrochemical cells.
