A monolithic carbon foam formed of fused onion-like carbon (OLC) nanoparticles, in which the monolithic carbon foam contains interconnected pores, has a volumetric micropore surface area of 200 m/cc-600 m/cc, and has an electrical conductivity of 20 cm-140 S/cm. Also disclosed are a fractal carbon foam prepared from the monolithic carbon foam, methods of preparing both foams, and supercapacitors constructed therefrom. Specifically, the methods of preparing the foams comprising, inter alia, spark plasma sintering the OLC nanoparticles at a pressure of 30 MPa-1000 MPa and a temperature of 300° C.-800° C. for 2 seconds-30 minutes.
