• Artificial Graphite an overview | ScienceDirect Topics

    Artificial graphite (nongraphitic carbon) is fabricated by heat treatment of petroleum coke, coaltar 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

  • Using Waste to CostEffectively Produce Graphene

    The ability to create graphene from household waste negates one of the highest costs within the production process—the cost of the raw graphite products used in the exfoliation processes (which can be $10003500 per ton, compared to coal, which is $25 a ton) Compared to CVD processes, it is also a much cheaper and lesscomplex method
