The carbon electrode is made of the carbon isotropic structure of graphite. Allotrope is a fancy word used to describe the structure of a material made up of a single element. in terms of how the atoms in that structure organize themselves. How do the atoms in these structures organize themselves? it is usually made up of many hexagonal carbon atoms stacked, which in turn bond into more hexagons to form a layer of graphene, one carbon atom thick. But while graphene is one atom thick and has incredible compressive strength, the bonds between each piece of graphene are much weaker and fundamentally different, so graphite naturally emerges as a fairly soft and slightly brittle material. This form of "α-graphite" is structurally different from the diamond-shaped crystal structure of "β-graphite", and the amorphous form of graphite glass, like most glass, is a randomly tightly packed structure.

        Carbon electrodes are not metals, they are technically semi-metallic, but under the right conditions are conductive enough to be used as conductors in some cases. It is also chemically less susceptible to degradation by ce rtain electrochemical reactions, is considerably chemically inert, and is much cheaper than using a chemically inert electrode made of platinum group metals， Platinum group metals are more expensive than gold.

    Graphite is an extremely fire-resistant material. It means it is suitable for working in extreme heat environments, such as inside electric arc furnaces, the graphitization furnace for producing graphite products, the furnace for melting glass, and the electric furnace for producing silicon carbide. They are always used as a vessel for metal smelting and as an electrode in welding, cutting operations, and EDM applications. Graphite is also widely used in life. Mix and match with the adhesive to become the motors. In the previous design of motors, relays, contactors, switches, and generators with high hardness and lubricity, arc melting will lead to the welding and closing of metal electrical contacts, and the strong current resistance of graphite makes it more suitable for the production of resistors and variable resistors.

       Graphite is widely used in life, such as early light sources, speakers, microphones and so on. Most carbon-zinc chemicals have been consistently sold over the long term. For example, batteries using carbon electrodes, zinc and electrolytes (liquid charge carriers) are still sold today because of their low cost and long shelf life.
