▎ 摘 要
NOVELTY - Method for preparing graphene and carbon 60 composite material involves adding graphite oxide to 5 l deionized water to obtain 0.5-1 mg/ml graphite oxide solution, performing ultrasonic processing on the obtained graphite oxide solution and adding 0.2-0.8 g carbon 60, sealing and heat-treating the obtained mixture, magnetically stirring, filtering and drying the obtained product, where the mass ratio of the graphite oxide and carbon 60 is 10:1-10:5. USE - The method is useful for preparing graphene and carbon 60 composite material (claimed) which is used in electrochemical capacitor as electrode active material. ADVANTAGE - The method enables to prepare product which has low agglomeration of the graphene sheet, and high energy storage capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene and carbon 60 composite material.
