▎ 摘　　要

NOVELTY - Preparing graphene by electrochemical intercalation of high concentration organic salt aqueous solution comprises taking high concentration organic salt aqueous solution as electrolyte, graphite as an anode and an inert conductive precious metal material as a cathode, performing an electrochemical intercalation reaction to obtain a graphene aggregate, where mass concentration of organic salt in the high concentration organic salt aqueous solution is greater than or equal to 50%, or volume concentration of organic salt in the high concentration organic salt aqueous solution is greater than or equal to 50% and organic salt is a bistrifluoromethanesulfonimide salt and/or a triflate salt. USE - The method is useful for preparing graphene by electrochemical intercalation of high concentration organic salt aqueous solution. ADVANTAGE - The method: has short preparation period, no acid solution, is economical, environmentally-friendly, simple and easy in industrialized mass production.
