Corrigendum: Binder-Free Flexible Chickpea Pod Derived Activated Carbon-Carbon Nanofiber Composite for Supercapacitor Application [ECS J. Solid State Sci. Technol., 13, 011104 (2024)]

Abstract

The published paper was produced from a poorly-edited file which resulted in numerous typographical and grammatical errors, leading to confusion about the experiments and results reported. The paper has been edited and the corrected version is shown here. In the present study, a novel carbon-carbon composite electrode was prepared by embedding activated carbon derived from chickpea pods and evaluating its potential as an electrode for supercapacitors. A simple, single-step electrospinning technique was used for the synthesis of activated carbon-carbon nanofiber composite. The synthesized activated carbon-carbon nanofiber composite electrode is flexible and binder-free with high specific surface area, micro and meso pores, interconnected fiber-to-flake morphology, and possesses high graphitization. Additionally, rapid electrolyte diffusion has resulted in a low charge transfer resistance due to interconnected morphology. In 6 M KOH electrolyte, the composite binder-free electrode shows a specific capacitance of 147 F g−1 at 0.5 A g−1 compared to activated carbon electrodes that showed a specific capacitance of 120 F g−1 at 0.5 A g−1. It exhibits an energy density of 13 Wh k g−1 at 0.366 W k g−1 power density and also shows impressive cyclic stability by retaining 93.5% of initial capacitance till 1200 cycles at 1 A g−1. Overall, the study presents an easy-to-use, low-cost, eco-friendly, and flexible electrode for supercapacitors that is free of binder.
