Hydrothermal Synthesis of Binder-Free Kapok (Ceiba pentandra) Fiber Paper-NiCo₂O₄ Supercapacitor Electrode

Abstract:

There is a need to address the gap between the theoretical benefits and cost-efficient production of supercapacitors in the market in order to sway the preference of the industry from the current perishable energy sources and storage. More extensive exploration of sustainable fabrication methods and materials used for renewable energy storage are just some of the factors that would decrease this gap. A binder-free supercapacitor electrode made of NiCo₂O₄ and carbonized kapok fiber paper (CKFP) was successfully fabricated by hydrothermal process at relatively low temperatures. NiCo₂O₄ urchin-like structures were deposited on the surface of carbon fiber paper (CFP) and CKFP. XRD analysis confirmed the successful conversion of kapok fiber paper to CKFP after pyrolysis, as well as the growth of pure spinel NiCo₂O₄ nanostructures on CFP and CKFP. The cyclic voltammetry curves showed that the CFP-NiCo₂O₄ prepared at 140 °C had the highest specific capacitance of 143.51 Fg^-1 at 2 mVs^-1. The CKFP-NiCo₂O₄ synthesized at the same temperature yielded slightly higher specific capacitance of 146.29 Fg^-1 at 2 mVs^-1, and 508 Fg^-1 at 0.5 Ag^-1.
