NOVELTY - Preparing super capacitor graphene nanosheets involves mixing asphalt, potassium hydroxide and nano-magnesium oxide into a mortar to obtain homogeneous mixture. The homogeneous mixture is placed in a corundum porcelain boat, where the corundum porcelain boat is heated in a furnace in presence of argon gas at 200 degrees C for 30 minutes. The obtained material is heated at 800-900 degrees C,and then naturally cooled. The obtained material is processed with dilute hydrochloric acid, and then washed with distilled water. The material is filtered, and then dried to obtain super capacitor graphene nanosheets. USE - Method for preparing super capacitor graphene nanosheets (claimed). ADVANTAGE - The method enables to prepare super capacitor graphene nanosheets in a simple and cost-effective manner.
