Eco-friendly and Renewable Synthesis Routes for High-Performance Carbon based Supercapacitors

초록

In response to the growing demand for eco-friendly technologies in the Industry 4.0 era, carbon based energy storage materials are evolving toward sustainable and high-performance applications. This work introduces a series of novel approaches for the synthesis of clean and renewable carbon based materials for supercapacitor devices. First, a plasma-induced photothermal reduction method was developed to convert graphene oxide (GO) into reduced GO, eliminating the use of strong acid based chemical reduction. Second, a facile and cost-effective electrodeposition technique was employed to fabricate a flexible supercapacitor, offering excellent electrochemical performance and mechanical durability. Third, a fully upcycled energy storage device was fabricated using heated tobacco waste as a sustainable carbon precursor, presenting a meaningful step toward resource recycling in the energy field. These strategies not only align with eco-conscious goals but also demonstrate outstanding specific capacitance and stability. Overall, this study provides insight into alternative synthesis routes for scalable, renewable, and high-performance carbon-based supercapacitor devices.
