The invention provides a preparation method of a graphene/molybdenum disulfide composite fiber fabric, which comprises the following steps: firstly, spinning graphene into a graphene fiber non-woven fabric by a wet method, and then loading molybdenum disulfide nanosheets under a hydrothermal auxiliary condition. The preparation method comprises the following main preparation steps: (1) preparing graphene oxide short fibers; (2) carrying out suction filtration and drying on the graphene oxide short fibers; and (3) placing the dried graphene oxide fiber non-woven fabric in a hydrothermal kettle, adding a certain mass of deionized water, a sulfur source and a molybdenum source, and carrying out a hydrothermal reaction to prepare the graphene fiber non-woven fabric loaded with the molybdenum disulfide nanosheets. Compared with the prior art, the graphene/molybdenum disulfide flexible non-woven fabric obtained by the invention has the advantages of self-supporting characteristic, excellent electrochemical performa
