Abstract: A method of electrochemical exfoliation, may include: electrochemically exfoliating a parent material comprising coke, wherein the electrochemically exfoliating comprises introducing the parent material into a porous chamber, applying pressure to the porous chamber to thereby compress the parent material in the porous chamber, and applying a potential bias to the parent material while at least a portion of the parent material is in contact with an electrolyte solution to produce a mixture of exfoliated material and unexfoliated parent material, wherein the exfoliated material comprises exfoliated graphene; and separating at least a portion of the exfoliated material from the unexfoliated parent material.
