The invention provides electrolyte slurry for preparing reduced graphene through liquid flow continuous electrochemical reduction of graphene oxide, and belongs to the technical field of graphene material preparation. The electrolyte slurry is composed of graphene oxide and an electrolyte, and the electrolyte is composed of an electrolyte, a solvent and an additive; the additive is a surfactant and/or a reducing reagent; the graphene oxide is pure graphene oxide or a graphene oxide mixture containing graphite or graphite oxide with a certain concentration. In the electrolyte slurry, the mass concentration of the graphene oxide is 0.01-100 g/L, and the concentration of the electrolyte in the electrolyte is 0.01-30 mol/L. The electrolyte slurry provided by the invention can be used for liquid flow continuous electrochemical reduction of graphene oxide, and reduced graphene can be produced continuously, stably, greenly and on a large scale at low cost.
