Abstract

Supercapacitors are crucial for the future of energy, offering exceptional power and longevity [1]. Nevertheless, their low energy density remains a significant barrier. To overcome this limitation, our research utilized iron oxide (FeOx)—a low-cost, abundant, and eco-friendly material with a high theoretical capacity [2]. However, to solve the issues of poor conductivity and instability of FeOx [3], we have created a novel hybrid material by combining it with melanin from Crotalaria longirostrata. This strategy enhanced conductivity, stability, and surface area [4]. Through co-precipitation synthesis, we optimized this material to achieve high capacitance, improved energy density, and robust cycle life, aiming to produce a practical, high-performance device for next-generation portable and advanced energy system. This study aims to synthesize and characterize a novel hybrid supercapacitor electrode composed of melanin and iron oxide (FeOx). The goal is achieving a device with a specific capacitance of at least 100 Fg⁻¹ and an energy density of at least 50 Whkg⁻¹, thereby demonstrating its potential as a sustainable and efficient energy storage solution.
