Abstract:
PURPOSE: A graphene electrode supercapacitor and a manufacturing method thereof are provided to increase capacity per unit volute of a graphene electrode by adding graphene powder and molasses. CONSTITUTION: A graphene mixture(100') is made by mixing graphene powder, conductive materials, molasse, polytetrafluoroethylene and dispersing medium. The graphene mixture is compressed by a press(130). The compressed molding is sintered at 150 to 400 degrees centigrade.
