▎ 摘  要

NOVELTY - Method for electrochemical preparation of high-quality graphene materials comprises (i) preparing electrolyte, configuring graphite material as anode in electrolyte, configuring metal or graphite material as cathode to form an electrochemical peeling system, where the electrolyte includes a bubble inhibitor, and the bubble inhibitor is sodium hydroxide, ammonia monohydrate, sodium carbonate and/or sodium bicarbonate, (ii) applying a voltage between the anode and the cathode, and controlling the electrochemical stripping system to keep heat at the low temperature section of 0-20 degrees C and the high temperature section of 40-95 degrees C respectively, making the graphite anode go through the low-temperature intercalation and high-temperature stripping stages successively to obtain electrochemical stripping products, and (iii) collecting the electrochemical stripping products, washing and drying to obtain high-quality graphene powder. USE - The method is useful for electrochemical preparation of high-quality graphene materials. ADVANTAGE - The method is simple and the reaction conditions are mild, the equipment requirements are low, easy to implement, the electrochemical system involved is environmentally friendly, and the preparation cost is low, which is very suitable for large-scale industrial production.
