Graphite coating process
WebGraphite is a layer lattice lamella crystal structure where the bonds between the carbon atoms in the crystal structure of the layer are stronger than the carbon bonds between layers. Graphite is comprised of carbon and water vapor. Each carbon atom is bonded to three other surrounding carbon atoms. WebIn order to obtain the high purity required for battery applications, the finely-distributed, so-called flake graphite which occurs naturally in stone, must be processed in various steps.
