Method of manufacturing graphene composite including ultrasonic-wave pulverization post-treatment process and method of manufacturing active material using the same

摘要

Disclosed is a method of manufacturing a graphene composite including an ultrasonic-wave pulverization post-treatment process. The method includes radiating a microwave on a mixture of graphite oxide and a conducting agent, dispersing a resultant material, obtained during the radiating the microwave, in a liquid and performing ultrasonic-wave pulverization, and freeze-drying particles subjected to the ultrasonic-wave pulverization. In the present invention, the post-treatment process is added to the method of manufacturing the graphene composite including the reduced graphene oxide using the graphite oxide, thereby manufacturing a graphene composite having improved bindability with spherical activated carbon used to manufacture an active material. Further, the post-treated graphene composite is used to manufacture the active material and the supercapacitor, and accordingly, the active material can be thinly and densely applied to provide a supercapacitor having improved performance.
