| Abstract: | Graphene-based supercapacitors have emerged as promising candidates for next-generation energy storage due to their exceptional electrical conductivity, large surface area, and mechanical stability. This paper reviews innovative fabrication techniques such as rapid thermal annealing, hydrothermal reduction, and microwave-assisted synthesis, which enhance the scalability, cost-effectiveness, and environmental sustainability of graphene synthesis. Specific capacitance values exceeding 200 F/g and cycle stability of over 15,000 cycles have been achieved with these methods, demonstrating their potential for high-performance energy storage applications. Microwave-assisted synthesis, for example, offers a 95% cycle retention rate over 15,000 cycles, outperforming conventional methods. The scalability of roll-to-roll CVD and eco-friendly processes like hydrothermal reduction are discussed, along with practical applications in flexible and wearable electronics. Furthermore, the role of graphene-based supercapacitors in electric vehicles, renewable energy systems, and portable medical devices highlights their growing relevance in industrial applications. The paper concludes with future prospects for commercialization and the integration of green synthesis strategies in industrial-scale graphene production. [ABSTRACT FROM AUTHOR] |
