The invention relates to the technical field of lithium batteries, in particular to a dispersion method for graphene for pulping of a lithium battery. The dispersion method comprises the steps of (1)pre-dispersing graphene conducting paste: (A) stirring and premixing, and (B) grinding; and (2) dispersing and preparing lithium-ion battery paste containing a graphene conducting agent: (I) preparinga PVDF glue solution, (II) adding the PVDF glue solution for the first time, (III) adding lithium cobalt oxide for the first time, and (IV) adding the lithium cobalt oxide and the PVDF glue solutionfor the second time. According to the dispersion method for the graphene for pulping of the lithium battery, the dispersion processes in the steps (1) and (2) are adopted and the PVDF glue solution and the lithium cobalt oxide are equally added twice in the dispersion process in the step (2), so that the dispersion uniformity of the graphene can be effectively improved, the graphene is uniformly dispersed, and the paste is free of obvious settlement and agglomeration after being placed for a long period of time.
