NOVELTY - Manufacturing a composite containing precursor and sulfur precursor involves forming a reduced graphene oxide (rGO) coating layer on the surface of the metal foam by performing a first hydrothermal reaction between the graphene oxide mixture and the metal foam, heat-treating the metal foam on which the coating layer is formed at 450-550 degrees C, using a nitrogen doping agent to doping nitrogen to prepare an intermediate and forming nickel cobalt sulfide on a portion of the surface of the intermediate by performing a second hydrothermal reaction between the intermediate and the first precursor composition. The first precursor composition includes a nickel (Ni) precursor, a cobalt (Co). USE - Method for manufacturing composite containing precursor and sulfur precursor, preferably composite containing nickel cobalt sulfide. ADVANTAGE - The composite have excellent electrical conductivity and storage capacity characteristics, excellent mechanical properties, structural stability, and lifespan characteristics, and are structural by excluding a binder during electrode manufacturing. It is excellent in stability, prevents deterioration in electrical conductivity, and can have excellent effects of preventing volume change and stability deterioration of the electrode during charging and discharging.
