Abstract
The adoption of more environmental friendly means of harnessing and storing energy while minimizing harmful effects on the environment is becoming more significant. Supercapacitors are becoming a more favored means of energy storage systems owing to their higher surface area electrodes and thinner dielectrics. For greater capacitances, a suitable material must have high porosity. Such a suitable material is carbon, most notably graphene, with superior electrical properties, chemical stability and high surface area. This review focuses on the types of mechanism for storing energy, the types of materials used in supercapacitors, and the applications and scope of supercapacitor research and development.
