"Graphite" is just a tall pile of such graphene layers drawn together by van der Waals bonding.

But because the van der Waals bonding is weak, graphene layers can be easily pulled back apart.

This occurs when tape is peeled off a piece of graphite (which was how graphene was first discovered!).

Graphite layers also separate easily when force is applied, making graphite a good lubricant.

Finally, because each graphene layer within a graphite stack retains its flickering "resonant" and "conjugated" bonding, graphite is an electrical conductor
