Graphite used in batteries comes in two forms, both of which have pros and cons. One is natural, dug from the ground—though the mines that produce the best grades are few and far between. The other is synthetic, coming from the roasting of so-called needle coke, a by-product created in some coal-processing and petrochemical plants.
This crystalline carbon allotrope is good for more than just pencils—it’s found in every EV battery anode, and producing graphite in the forms needed to build high-performance battery cells is a complex and exacting process. Graphex is a major global producer and distributor of graphite in its various forms.
Graphite for batteries currently accounts to only 5 percent of the global demand. Graphite comes in two forms: natural graphite from mines and synthetic graphite from petroleum coke. Both types are used for Li-ion anode material with 55 percent gravitating towards synthetic and the balance to natural graphite.
Not all forms of natural graphite are suitable for entry into the battery supply chain. Credit: IEA (CC BY 4.0) Graphite—a key material in battery anodes—is witnessing a significant surge in demand, primarily driven by the electric vehicle (EV) industry and other battery applications.
Here’s why graphite is so important for batteries: Storage Capability: Graphite’s layered structure allows lithium batteries to intercalate (slide between layers). This means that lithium ions from the battery’s cathode move to the graphite anode and nestle between its layers when the battery charges.
The mineral graphite, as an anode material, is a crucial part of a lithium-ion (Li-on) battery. Electrek spoke with John DeMaio, president of the Graphene Division of Graphex Group and CEO of Graphex Technologies.

ORNL researchers created and tested two methods for transforming coal into the scarce mineral graphite, which is used in batteries for electric vehicles and renewable energy storage. The U.S. Geological Survey has classified graphite as a critical material for energy because the domestic supply of natural graphite is so small, and foreign imports are limited.
Graphite is a crucial component of a lithium-ion battery, serving as the anode (the battery''s negative terminal). Here''s why graphite is so important for batteries: Storage Capability: Graphite''s layered structure allows lithium batteries to intercalate (slide between layers).
What types of batteries could be used for both transportation and grid applications? Picture a D-cell battery that once was the common perception of a battery. This kind of battery powered flashlights and toys, and had to be replaced once it was dead. Now, picture the need for lightweight, rechargeable energy storage systems that power our cars ...
There are three main forms of graphite: spherical graphite is used in non-EV battery applications, whereas EV batteries use a blend of coated spherical graphite and synthetic graphite. Graphite is the critical component of all current anode designs.

When used as negative electrode material, graphite exhibits good electrical conductivity, a high reversible lithium storage capacity, and a low charge/discharge potential. Furthermore, it ensures a balance between energy density, power density, cycle stability and multiplier performance [7].
The proper selection of the amount and type of graphite as well as the (post-)processing, however, were found to be crucial for obtaining such remarkable performance – also with regard to the subsequent calendaring of the electrodes which is essential for achieving high volumetric energy densities. 331,332 When incorporating about 30% of graphite into the anode blend, the …
