Why can graphite be made into a conductive material?

Graphite anode conductivityEveryone should have some understanding, but why can graphite conduct electricity? How to make conductive materials? Let's explore together with the advanced science and technology editor below.

Because graphite contains freely moving charges, the charges can move freely after being electrified, forming an electric current, which allows it to conduct electricity. The real reason why graphite conducts electricity is that six carbon atoms share six electrons to form a large π -66 bond at the center of six electrons. In the same layer carbon ring of graphite, all six membered rings form a π - π conjugated system, or in other words, in the same layer carbon ring of graphite, all carbon atoms form a huge large π - bond, and all electrons in this large π - bond can flow freely within the layer. This is the reason why graphite paper can conduct electricity.

Graphite is a layered structure with unbound free electrons between layers, which can move directionally when electrified. Actually, all substances conduct electricity, it's just a matter of the resistivity. The structure of graphite determines that it has the lowest electrical resistivity among carbon materials.

Graphite anode is conductive, and graphite particles made of graphite are also conductive. However, the effect varies depending on the type of material used. There are two types of graphite particles, one is small graphite particles like collagen material with a particle size greater than about 0.5 millimeters, which is roughly the coarsest powder crushed by a grinder. The other is processed from high-purity graphite and can be made in any specification. The characteristic of high-purity graphite is that it has high purity and restores the original physical properties of graphite. At the same time, it can also produce graphite products in different shapes, such as graphite electrode rods that require conductivity, graphite lubrication rods, graphite sheets for heat dissipation, various small-sized graphite particles, etc., all of which have the ability to conduct electricity. The unique characteristics of graphite, such as conductivity, lubrication, and high temperature resistance. After baking, high-purity graphite is immersed and baked at 1800 degrees Celsius to completely evaporate the adhesive used in the production of high-purity graphite materials. This highlights the conductivity of graphite, as the higher the purity of graphite, the better the conductivity effect.
