NOVELTY - The utility model specifically relates to a material adding system, the material adding system comprises: a plurality of solvent storage tanks, a graphene powder storage tank and a flow control mechanism; the flow control mechanism controls the discharge flow of several solvent storage tank and graphene powder storage tank. The material adding system of the utility model does not need manual operation, avoids the non-synchronism of manual feeding and proportion is difficult to control the influence of the mixed material.
