PROBLEM TO BE SOLVED: To improve the hydrophilicity of a raw material of conductive carbon black and control the size of the particle size of the prepared granular conductive carbon black. Granular conductive carbon black and a method for preparing the same belong to the technical field of conductive carbon black. The method for preparing the granular conductive carbon black includes, in order, wetting the raw material of the conductive carbon black with water having a temperature of 80 ° C. or higher, wet granulation, and drying. By infiltrating the raw material of conductive carbon black with water having a temperature of 80 ° C. or higher, the hydrophilicity of the raw material of conductive carbon black is improved, and water having a temperature of 80 ° C. or higher is the raw material of conductive carbon black. It can enter the micropore structure and has a good wetting effect. Further, wet granulation and drying prepare a granular conductive acetylene black having a uniform particle size. The prepared granular conductive carbon black has a particle size distribution of 0.6 to 1 mm and a secondary particle size distribution of 4 to 8 μm, which can be applied to general rubbers and resins, as well as new lead-acid batteries, lithium primary and secondary. It can also be applied to fields such as battery sum ultra-high pressure cables. [Selection diagram] None
