▎ 摘　　要

NOVELTY - Electrolytic cell (1) comprises a first electrode (2) and a second electrode (3) linked and separated, where both first and second electrodes are immersed in a liquid electrolyte (7) contained in a vessel (8). The first electrode and the second electrode are arranged in a horizontal plane as a functional condition for the obtention of graphene. The first electrode is placed in a plane above the second electrode. The second electrode features a confinement zone (4) where the graphite (6) to be exfoliated can be placed. The confinement zone is delimited by a confining non-conducting material (5). The confinement zone comprises a compacting element arranged in a plane parallel to the second electrode and in contact with the graphite to be exfoliated. The first and second electrodes are arranged in planes parallel between them. The electrodes are separated by a distance of at least 1 mm. The electrolyte leads to a non-stable dispersion of graphene. USE - The electrolytic cell is used for the fabrication of graphene by electrochemical exfoliation of graphite (claimed). ADVANTAGE - The highly efficient process produces graphene from any kind of graphite material, regardless of its aggregation state (monolithic, or as a powder), or crystallinity. The process is simple with minimal consumption of energy leading to a product easy to isolate, not requiring complex filtration processes and leading to graphene without impurities or defects. The process allows for an exfoliation process needing much less energy and time that required for more compact materials which in turn implies a process less aggressive leading to a product with very small amounts of defects and oxygen and at a reduced cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a process for fabricating graphene by electrolytic exfoliation of a graphitic material in the electrolytic cell. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electrolytic cell.
