Abstract
Disclosed is a device designed for a continuous production of graphene flakes by an electrochemical method. The device consists of an electrochemical unit for generating graphene flakes by an electrochemical exfoliation; a filtration unit for separating the graphene flakes from an electrolyte solution; a guiding path connected to the electrochemical unit and transports the graphene flakes and the electrolyte solution into the filtration unit; a grading collection unit for accepting the separated graphene flakes from the filtration unit and separating the graphene flakes by size. The device can achieve the effect of producing high-quality graphene flakes in mass production electrochemically, continuously and quickly.
