A novel ring-shaped NiS-poly-2-aminothiophenol NiO (NiS-P2ATP/NiO) core-shell nanocomposite has been successfully synthesized and extensively analyzed, presenting itself as a promising material for a two-electrode configuration pseudo-supercapacitor, tested in both basic and acidic mediums. The SEM analysis reveals the construction of open-ring shapes, characterized by a wall thickness of approximately 120 nm and a height of around 100 nm. To confirm the elements and crystallinity behavior of this nanocomposite, XPS and XRD analyses are used, while FTIR is performed to confirm the functional groups. The electrical properties of this nanocomposite were thoroughly investigated through various techniques, including charge/discharge, cyclic voltammetry, and EIS. The efficiency of the fabricated supercapacitor was assessed through measured specific capacitance (CS), energy density (E), power density (P), Ragone plot, and the values of RS and RCT resistances. The specific capacitance value is significantly higher at 59.8 F/g compared to the basic medium's CS value of 30 F/g. In the acidic medium, the E values reached 5.0 W h kg-1, while in the basic electrolyte, it amounted to 2.5 W h kg-1. The produced P achieved impressive values, reaching 28800 and 28700 W/kg at 0.2 A/g in the acidic and basic mediums, correspondingly. The unique behavior of this novel composite suggests its potential for industrial applications of polymer materials, given its ease of preparation, mass production feasibility, and cost-effectiveness. The findings of this study open doors for the practical implementation of such innovative materials in energy storage technologies.

A highly efficient MnO2-Mn2O3/Poly-2-methylaniline (MnO2-Mn2O3/P2MA) hexagonal nanocomposite is synthesized using a one-pot technique involving oxidation polymerization. The hexagonal morphology and crystalline nature of this nanocomposite, as evidenced by the XRD pattern, affirm its exceptional characteristics. The electrical properties are assessed through charge/discharge behavior and cyclic voltammetry curves, elucidating the storage capabilities of this pseudo supercapacitor using different electrolytes NaOH and HCl. The fabricated supercapacitor exhibits impressive efficiency values of 22 F/g in a basic medium and a notably higher 72 F/g in an acidic medium at a current density of 0.2 A/g. Similarly, the power density values are calculated at 480 and 478 W.kg-1 for the basic and acidic electrolyte, correspondingly. In the basic medium, the series resistance (RS) and charge transfer resistance (RCT) are 5.2 and 0.7 Ω, respectively. In the acidic medium, these values are notably lower, with RS at 2.82 Ω and RCT at 0.2 Ω. Remarkably, even after 500 cycles, the supercapacitor stability remains high at 95% in both media, underscoring the enduring stability attributed to the oxides and polymer materials within the supercapacitor. The combination of cost-effectiveness, ease of fabrication, and potential for mass production positions this supercapacitor as a promising candidate for industrial applications of polymer-based supercapacitors.
