Artificial graphite of bulk form is made by adding a binder to a carbon-based filler, i.e. coke and tar, followed by heat treatment .In general, heat treatment is performed at 2500℃-3000℃ but higher temperature is required to achieve a structure closer to that of natural graphite [24-26].The first commercial artificial graphite of bulk form was synthesized by Edward Goodrich Acheson.

Artificial graphite (nongraphitic carbon) is fabricated by heat treatment of petroleum coke, coal-tar pitch, or oil. Specific capacity and reversibility is lost at high temperatures from 1000 Ah kg −1 (at 500 °C) to 150 Ah kg −1 (1800 °C). Above 2000 °C, an increasing degree of graphitization improves capacity again (200–300 Ah kg −1) and minimizes irreversible charge.

In the first step of artificial graphite production, the run‐of‐kiln coke is crushed, sized, and milled to prepare it for the subsequent processing steps. The size of the largest particle is generally set by application requirements. The manufacturing process begins with the mixing operation.

There are many kinds of synthetic graphite, and the production process varies widely. All graphite materials obtained by carbonization of organic matter and high-temperature treatment by graphitization can be collectively referred to as artificial graphite, such as carbon (graphite) fiber, pyrolytic carbon (graphite), ed graphite and the like.
