The invention discloses a batch preparation method of graphene. The method comprises the following steps of: S1, injecting graphite flakes and a stripper into a ball-milling tank, wherein the stripper comprises 100 parts of water, 1-10 parts of naphthalene sulfonate and 1-3 parts of sand milling agent; S2, carrying out ball milling for 4-48 hours, wherein the speed of a ball mill is over 2000rpm/min; S3, discharging upper layer suspension into a material storage tank after stopping reaction, and standing; S4, conveying graphene suspension to a centrifuge to be centrifuged and carrying out vacuum filtration on supernatant after centrifuging to obtain a filter cake; and S5, washing and freeze-drying the filter cake. The preparation method has the advantages that equipment is not corroded and the graphene structure is not damaged while graphene is stripped.
