NOVELTY - Supercapacitor electrodes preparation involves mixing graphene oxide colloid with activated reducing agent under stirring to obtain suspension, drying and pulverizing to make electrode slurry, and then adding binder, auxiliary solvent and conductive agent to obtain mixture. The formed electrode slurry is coated on copper foil electrode sheet, dried, and pressed to prepare the copper foil electrode sheet. The prepared copper foil electrode sheet is placed in a microwave radiation furnace cavity, vacuumed under argon gas, where the single-mode microwave magnetic field is irradiated. The output power of the microwave device is adjusted to 100-200 watts for 30-60 seconds. USE - Method for preparing supercapacitor electrodes by using modified graphene oxide. ADVANTAGE - The method prepares the supercapacitor electrodes by using modified graphene oxide in a simple, cost-effective and eco-friendly manner.
