Graphite is an amorphous form of carbon, made of carbon atoms bound hexagonally in sheets. It is used as a thermal-insulating electrical-conductor, as a nuclear-reactor moderator and as a self-lubricant. In lithium ion batteries it is used as the anode. In battery cells we see the use of natural and synthetic graphite.
