1. A method of producing carbon material from coal, the method comprising:
subjecting the coal to a dissolution process to produce a solubilized coal material; and
subjecting the solubilized coal material to a pyrolysis process to produce carbon material, the pyrolysis process including heating the solubilized coal material to between 250° C. and 380° C. for 1-8 hrs and then heating the solubilized coal material to temperatures as low as 700° C. for at least 1 hr.
