NOVELTY - Preparation of ferroferric oxide/graphene composite material involves taking anhydrous sodium acetate, anhydrous sodium citrate and 0.2800 g anhydrous ferric chloride, placing in 30 mL ethylene glycol, magnetically stirring at speed of 300 revolutions/minute for 2 hours to obtain iron precursor suspension and dispersing graphene oxide in 30 mL ethylene glycol to obtain graphene oxide ethylene glycol suspension. USE - Method for preparing ferroferric oxide/graphene composite material used for preparing energy storage supercapacitor electrode (claimed). ADVANTAGE - The product has good synergistic effect; and provides anode materials with good cycling performance and good cycling performance. DETAILED DESCRIPTION - Preparation of ferroferric oxide/graphene composite material comprises taking anhydrous sodium acetate, anhydrous sodium citrate and 0.2800 g anhydrous ferric chloride, placing in 30 mL ethylene glycol, magnetically stirring at speed of 300 revolutions/minute for 2 hours to obtain iron precursor suspension, dispersing graphene oxide in 30 mL ethylene glycol to obtain graphene oxide ethylene glycol suspension, placing graphene oxide ethylene glycol suspension and iron precursor suspension in reactor, sealing, reacting at 205 degrees C for 15-30 hours, cooling to room temperature, separating by magnet to obtain solid sample, washing with deionized water and vacuum drying at 50 degrees C.
