Abstract
Carbon-based materials have emerged as attractive possibilities for supercapacitor applications due to their high electrical conductivity, huge surface area, and excellent stability. The potential of carbon materials, like carbon allotropes and activated carbon derived from biowaste, to enhance supercapacitor performance is examined in this paper. Activated carbon remains popular due to its high surface area and low cost, but improvements in CNTs and graphene provide enhanced conductivity and structural adaptability, increasing energy and power density. It also examines the creation of carbon composites, which combine the benefits of carbon and other materials to improve supercapacitor qualities. The main factors influencing supercapacitor performance are discussed, focusing on surface modification and nanotechnology, including electrode design, pore structure, and electrolyte compatibility. Recent study findings emphasize the relevance of sustainable synthesis processes and the materials' scalability for commercial applications. The analysis continues by identifying potential prospects in carbon-based supercapacitor research, including the incorporation of environmentally friendly material production methods and the improvement of cyclic stability for long-term use in energy storage devices. This analysis provides a solid foundation for future advancements in high-performance supercapacitor technology.
