NOVELTY - Preparing three-dimensional graphene/molybdenum disulfide composite material, comprises (a) preparing three-dimensional graphene, (b) dissolving molybdate, deionized water and thioacetamide to form homogeneous reaction solution, and (c) impregnating the three-dimensional graphene in the homogeneous reaction solution, hydrothermally reacting, repeatedly rinsing the three-dimensional graphene by removing out, filling the rinsed three-dimensional graphene under inert gas atmosphere, and annealing to prepare composite material of three-dimensional graphene and molybdenum disulfide. USE - The method is useful to prepare three-dimensional graphene/molybdenum disulfide composite material for lithium-ion battery of mobile phones, laptops, digital cameras, and electronic translators. ADVANTAGE - The method provides composite material having lower electrode potential, higher specific capacity, excellent cycle stability, inherent low electron/ionic conductivity, and good compatibility with battery components i.e. electrolytes and adhesives, and forming stable solid electrolyte interphases film and bond with electrolyte, and is simple, economical and environmentally friendly. The composite material provides lithium-ion batteries having high voltage, high energy, no memory effect, long service life, no environmental pollution and other characteristics, provides graphite cathode having theoretical capacity of 372mAh/g, and improves performance of lithium-ion battery, and volume expansion during deintercalation of lithium.
