ELECTROLYTIC CELL AND METHOD FOR OBTAINING GRAPHENE BY MEANS OF ELECTROCHEMICAL EXFOLIATION

摘要

The present invention relates to an electrolytic cell (1) for obtaining graphene by means of electrolytic exfoliation of graphite (6), comprising a first electrode (2) and a second electrode (3) linked to each other and spaced apart, and both electrodes submerged in a liquid electrolyte (7) contained in a vessel (8), where both electrodes (2, 3) are arranged parallel and in a horizontal plane in a functional condition where graphene is obtained, wherein the first electrode (2) is located right above the second electrode (3), the second electrode (2) presenting a confinement zone (4) (materialized by a confining non-conductive material (5)) wherein the graphite (6) to be exfoliated is contained,. The invention also relates to the process for obtaining few-layers graphene in said electrolytic cell.
