▎ 摘　　要

NOVELTY - Counter electrode device comprises a metal counter electrode plate. The electrode plate is placed in an insulated ion exchange membrane support frame. The part of the electrode plate protruding from the ion exchange membrane support frame forms a strip-shaped electrode lug. The lead electrode ear is clamped by the insulating plate. The shape of the insulating plate and the conductive electrode lug is mirror-symmetrical. The shape of the symmetrical portion of the conductive electrode lug is the same as the insulating lug. Each partition frame is provided with an ion exchange membrane that is hermetically connected to the partition frame. When the ion exchange membrane support frame extends into the electrode tank and the upward end is provided with a set of air guide holes. The ion exchange membrane support frame extends into the lower part of the electrode tank with a set of liquid conducting holes. The counter electrode device is fixed on the bus bar in a suspended manner. USE - The counter electrode device is useful for preparing graphene by electrochemical exfoliation . ADVANTAGE - The counter electrode device: has low cost, safety, high efficiency, simple operation, and has continuous production. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the counter electrode device.
