A carbon electrode is a conductive material made primarily from carbon, often used in electrochemical applications. These electrodes can be found in various forms, such as rods or plates, and are commonly used in batteries, fuel cells, and electrolysis processes. Their ability to conduct electricity while being resistant to corrosion makes them valuable in many industrial and laboratory settings. In electrochemical cells, carbon electrodes serve as the sites for oxidation and reduction reactions. They can be combined with other materials to enhance performance, such as in lithium-ion batteries where they are paired with graphite to improve energy storage. Their versatility and efficiency make carbon electrodes essential components in modern technology.
