"WebArtificial graphite 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. • " - Graphite specific heat vs temperature
