Abstract

Novel nanostructured Fe ₂ O ₃ with a network of 3D mesoporous nanosheets was synthesized by depositing on carbon fabric (Fe ₂ O ₃ @CF) for use as an anode using a potentially low-cost electrodeposition technique. The electrode with freestanding binder-free Fe ₂ O ₃ @CF of high surface area displayed an exceptional specific capacitance of 394.2 F g ⁻¹ . Moreover, a flexible solid-state asymmetric supercapacitor (ASC) was fabricated with a negative electrode based on Fe ₂ O ₃ @CF and a positive electrode based on MnO ₂ @CF in the presence of PVA-LiCl as gel electrolyte. The above ASC exhibited a high operating potential up to 1.8 V, a favorable specific capacitance of 93.5 F g ⁻¹ (2.92 F cm ⁻³ ), long-term stability (91.3% retention of initial value over 5000 cycles), and remarkable mechanical stability and flexibility, suggesting its potential application for wearable electronics.
