The invention discloses a novel large-scale preparation method of a flaky molybdenum disulfide/nickel sulfide-graphene composite. The specific preparation method of the composite includes the following steps that firstly, graphite is prepared into graphene oxide through a chemical method, and graphene oxide is dispersed in deionized water; secondly, commercially-purchased sodium molybdate (Na2MoO4.2H2O), nickel chloride (NiCl2.6H2O) and thiourea (CS(NH2)2) are dissolved in the deionized water; thirdly, a certain amount of ethylene glycol (EG) is added into a solution obtained in the second step, and ultrasonic treatment is carried out; fourthly, suspension obtained in the third step is transferred into a hydrothermal reaction kettle to be sealed, a reaction product is obtained through a one-step hydrothermal method, and the reaction product is naturally cooled to the room temperature, repeatedly subjected to centrifugal washing with absolute ethyl alcohol and dried. The synthetic flaky molybdenum disulfide/ni
