▎ 摘　　要

NOVELTY - Rapidly preparing graphene in batches comprises adding carbon source precursor in the electrolyte, inserting electrode is electrified, filtering, and taking the precipitate after filtering and drying to obtain the graphene nano sheet. USE - The method is useful for rapidly preparing graphene in batches. ADVANTAGE - The method has short preparation time, large amount of reagent consumption and high energy consumption. The graphene has high yield, uniform structure, and average thickness of 0.7-1.5 nm.
