▎ 摘  要

NOVELTY - Production of graphene involves providing an electrochemical cell which consists of working electrodes, counter electrodes and aqueous electrolyte comprising exfoliating ions, exfoliating the working electrode to produce high quality graphene having characteristics that engineered for targeted applications. USE - Production of graphene. Uses include but are not limited to battery, supercapacitor, solar cell, sensor, electrocatalyst, electron field emission electrode, transistor, artificial muscle, electroluminescent electrode, water purification adsorbent, etc. ADVANTAGE - The method is less aggressive, economical, environmentally-friendly, and applicable on both laboratory scale and high volume scale of high quality graphene flakes having large size and reduced defects. The method does not require acid and large quantities of raw materials, and efficiently engineers characteristics of graphene by varying duty cycle of electrochemical process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the electrochemical cell. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of electrochemical cell set-up.
