NOVELTY - Preparing super capacitor interconnected folded graphene material involves keeping the template in a mortar and then grinding the selected material with activating agent to obtain a mixture. The obtained mixture is added with carbon source and N,N-dimethylformamide in a beaker and then the obtained material is stirred. The stirred material is subjected to perform ultrasonic oscillation treatment for 1 hour and then the treated material is kept for 12 hours, where the carbon source is anthracene, template is nano magnesium oxide, activating agent is potassium hydroxide. USE - Method for preparing super capacitor interconnected folded graphene material (claimed). ADVANTAGE - The method enables to prepare super capacitor interconnected folded graphene material in simple and cost-effective manner, and with high capacity and energy density. DETAILED DESCRIPTION - Preparing super capacitor interconnected folded graphene material involves keeping the template in a mortar and then grinding the selected material with activating agent to obtain a mixture. The obtained mixture is added with carbon source and N,N-dimethylformamide in a beaker and then the obtained material is stirred. The stirred material is subjected to perform ultrasonic oscillation treatment for 1 hour and then the treated material is kept for 12 hours, where the carbon source is anthracene, template is nano magnesium oxide, activating agent is potassium hydroxide, mass of activating agent and carbon source of total mass is 40.0-44.4 wt.%. The interconnected folded graphene material is prepared by keeping the obtained material in corundum porcelain boat in a tubular furnace. The obtained material is heated at 300 degrees C under argon gas atmosphere for 30 minutes and then the heated material is further heated at 800-1000 degrees C for 1 hour. The heated material is cooled to room temperature and then the cooled material is ground and washed with diluted hydrochloric acid. The washed material is further washed with distilled water and then the washed material is dried to obtain the desired product.
