A molybdenum disulfide/graphene/carbon composite material having a hierarchical pore structure includes a composite nanofiber having a diameter of 60 to 500 nm. The composite nanofiber comprises, in mass percentage, 3% to 35% of molybdenum disulfide, 0.2% to 10% of graphene, and 60% to 95% of carbon. The composite nanofiber has a hierarchical pore structure distributed along the axial direction, and has a pore diameter continuously distributed between 0.1 nm and 5 μm and an average pore diameter between 1.5 nm and 25 nm. On the basis of the pore volume, in the hierarchical pore structure, a micropore structure accounts for 25% to 60%, and a mesoporous structure accounts for 40% to 75%. The microporous structure is distributed on the surface of the nanofiber and the pore wall of the mesoporous structure.
