What Is Graphite?

An important input material for modern life, Graphite is all around you — it’s in your smartphone, television, computer, tablet, and in all lithium-ion batteries.

A non-metallic mineral, Graphite is one of two natural forms of carbon (the other is diamond). With the highest natural strength and stiffness of any material, graphite is an excellent conductor of heat and electricity. It is stable over a wide range of temperatures. Graphite is a highly refractory material with a high melting point (3650°C). Graphite has a high natural lubricity and is one of the lightest of all reinforcing agents. While chemically inert, Graphite also has a high resistance to corrosion.

Graphite, specifically, Coated Spherical Graphite — or ‘CSPG’ — is used to manufacture the anode in a Lithium-ion (Li-ion) battery.
