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 1000kg −1 (at 500 °C) to 150kg −1 (1800 °C). Above 2000 °C, an increasing degree of graphitization improves capacity again (200–300kg −1) and minimizes irreversible …
