▎ 摘　　要

NOVELTY - The device has an electrolytic groove (1) whose upper end is formed with a fixing pole (2) which is fixed with metal blocks. The metal blocks are connected with graphite working electrode (4) and molybdenum filament (5). The graphite working electrode and the molybdenum electrode are extended into the electrolytic groove of metal blocks through a lead and are connected with alternating current power supply. The electrolytic groove is filled with potassium sulfate electrolyte. USE - Electrochemical stripping efficient device for preparing graphene used for touch screen, display, printing device, light emitter and solar energy battery. ADVANTAGE - The honeycomb lattice structure is prevented from damage and the large scale graphene production is achieved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of electrochemical stripping efficient device for preparing grapheme.
