    Research output: Patent


    The present invention provides a method for the production in an electrochemical cell of one or more of graphene, graphite nanoplatelet structures having a thickness of less than 100nm, and graphane, wherein the cell comprises: (a) a negative electrode which is graphitic; (b) a positive electrode which may be graphitic or another material; and (c) an electrolyte selected from (i) an ionic liquid; (ii) a deep eutectic solvent; and (iii) a solid ionic conductor, optionally further comprising (iv) one or more ionic species, wherein the amount of (i), (ii) or (iii) and (iv) is greater than 50wt% based on the total weight of the electrolyte; and wherein the electrolyte includes a mixture of different cations; and wherein the method comprises the step of passing a current through the cell to intercalate ions into the graphitic negative electrode so as to exfoliate the graphitic negative electrode.
