A method for producing a nano- or micro-sheet element is provided, the nano- or microsheet element particularly being made of graphene and/or other sheet-materials. The method is based on a laminate (14) comprising at least a growth substrate (1) and a nano- or micro-sheet layer (2). The nano- or micro-sheet layer (2) is adapted to form the nano- or micro-sheet element. The method comprises at least the step of electrochemical delamination of the laminate (14) by means of electrolysis in such a way, that the growth substrate (1) is separated from the nano- or micro-sheet layer (2). In the electrochemical delamination of the laminate (14), a gas diffusion electrode (21) attached to the nano- or micro-sheet layer (2) is used as an anode and an electrolyte membrane, in particular a polymer electrolyte membrane (20), is arranged between the gas diffusion electrode (21) and the nano- or micro-sheet layer (2).
