NOVELTY - Preparing heterojunction bridged sulfurized graphene aerogel comprises (i) dissolving vanadium source and cobalt source in deionized water, stirring ultrasonically to make them uniformly dispersed, dropping to graphene solution to obtain a mixed solution, vigorously stirring for 30 minutes, hydrothermally self-assemblying and high-temperature vulcanizing to obtain mixed solution, (ii) moving mixed solution to reaction kettle and obtaining a composite hydrogel, (iii) immersing composite hydrogel in configured dialysate containing water and ethanol for dialysis to remove impurity ions to obtain hydrogel, (iv) placing hydrogel on freezing layer of refrigerator for freezing, taking out and placing indoors for natural drying to obtain a composite aerogel precursor, and (v) placing composite aerogel precursor and thiourea into a horse boiling furnace and subjecting to high temperature annealing to obtain final CoV2O xSy/CoV2O6 heterojunction bridged sulfurized graphene aerogel. USE - The aerogel is useful as electrode material of supercapacitors (claimed). ADVANTAGE - The aerogel is good for reducing ion diffusion resistance and has multi-dimensional electronic transmission path and enlarges the specific surface area, increases the active position, improves the electronic transmission conductive behaviour, and greatly improves the charge storage, provides large surface area for charge storage and effective charge storage and activates the pseudo-capacitor material to improve the capacitance performance of the electrode material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use method of heterojunction bridging sulfurized graphene aerogel as the electrode material of supercapacitors, comprising (i) washing the current collector titanium sheet with distilled water, ethanol and acetone successively to remove the surface oxide layer and oil stains; and (ii) pasting the composite electrode material on the titanium sheet of the current collector with silver paste, and performing vacuum drying treatment to obtain the electrode material of the super capacitor, where glass sheet is placed on composite electrode material, and used to press the composite electrode material onto the electrode material.
