  • Publication number: 20220250914
    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.

  • Publication number: 20210285115
    Abstract: Processes and systems for electrochemical exfoliation that use a compression reactor and, more particularly, to processes and systems for electrochemical exfoliation of planar parent materials, such as graphite. A reactor for electrochemical exfoliation may include a container configured to hold an electrolyte solution. The reactor may further include a porous chamber, wherein the porous chamber is configured to hold a parent material in fluid communication with the electrolyte solution. The reactor may further include a pressure source positioned to apply a pressure along a length of the porous chamber to thereby compress the parent material in the porous chamber. The reactor may further include a first counter electrode. The reactor may further include a working electrode. The reactor may further include an electrical power source in electrical communication with the first counter electrode and the working electrode.
