▎ 摘　　要

NOVELTY - Production (M1) of graphene and graphite nanoplatelet structures having a thickness of less than 100 nm in an electrochemical cell, where cell comprises negative electrode which is graphitic; positive electrode which may be graphitic or another material; and electrolyte which comprises ions in solvent where the cations are organic ions and metal ions; and where method (M1) involves the step of passing current through the cell. USE - For the production of graphene and graphite nanoplatelet structures (claimed). ADVANTAGE - The method produces graphene sheets with a controlled number of layers and flake size. The method is scalable and can produce graphene on a large scale.
