Abstract

Supercapacitors have played an important role in electrochemical energy storage. The performance characteristics of supercapacitor devices greatly depend not only on the electrode design but also on the core materials used in the electrode. In this study, we synthesised a new class of ternary materials that require simple methods of synthesis, involving a covalent organic framework (COF)-NiCo2O4-N-doped nanocomposite using a cost-effective hydrothermal route of synthesis. Composite electrode of COF/NiCo₂O₄-N-doped was developed that exhibited a high specific capacitance of 1,283.3 F g-1 at a discharge current density of 2 A g-1 when measured using a three-electrode setup. To show the potential of using COF/NiCo₂O₄-N-doped electroactive materials to create a practical and functional device, we fabricated an asymmetric supercapacitor (ASC) out of the COF/NiCo₂O₄-N-doped composite as the positrode and activated carbon (AC) as the negatrode in an electrolyte of 3 M KOH. The fabricated ASC device, COF/NiCo₂O₄-N-doped//AC exhibited impressive 34.59 Wh kg-1 and 1235.75 W kg-1 energy and power density ratings, respectively at a 2 A g-1 discharge current density, which maintained 90% rate of performance after 10,000 cycles of operation. Thus, the current study presents an efficient electrode material for deployment in energy storage devices of the future.
