摘要

Developing cost effective and superior electrode martials is crucial for advanced energy storage technologies. The exceptional electrochemical performance of nano-composites makes them attractive options for these kinds of applications. In this study, iron manganese trioxide/polyaniline (FeMnO3/PANI) was synthesized by a hydrothermal method and investigated through structural, morphological, and surface analyses. The composite displayed a higher surface area (84.2 m2/g) compared to pristine FeMnO₃ (38.6 m2/g), which provided more active sites and improved ion diffusion. Electrochemical testing revealed a specific capacitance of 1276 F/g, with an energy density of 28.08 Wh/kg at 1 A/g and a power density of 199 W/kg. Impedance analysis further indicated a low charge transfer resistance (Rct) of 0.47 Ω, reflecting efficient charge transport. Additionally, the electrode showed exceptional cyclic stability over 3450th cycle emphasizing its robustness. These synergistic effects between FeMnO3 and PANI develops surface activity and charge mobility, forming the FeMnO3/PANI nanohybrid a highly attractive electrode for upcoming generation supercapacitor (SCs) and other advanced energy storage technologies.
