Abstract:

Supercapacitors (SCs) are seen as potentially useful energy storage devices that integrate the qualities of both batteries and capacitors. They have low cost, high cyclic stability, and high-power density. Innovative and electrochemically efficient SCs seek the exploration of key electrode materials. In the present work, a facile and cost-effective hydrothermal technique has been employed to prepare Cerium (Ce) doped manganite nanostructure (NiCe_xMn_2−xO₄) with x = 0.00, 0.08, 0.10. XRD, BET, and SEM were employed to examine the structure, porosity, and morphology. It was noted that the dopant Ce showed its impact. Dopant with 8% revealed a high surface area and suitable morphology. Further Ce showed its impact on electrochemical characteristics. The fabricated SC comprising optimum dopant (x = 0.08) displayed a substantial capacitance of ~ 102.94 F g⁻¹. SC also exhibited high specific power (14.55 kW kg⁻¹) and energy (3.57 Wh kg⁻¹) with excellent cyclic stability (93.4%) for more than 5000 discharge cycles. Therefore, one can argue that efficient manufacturing material together with excellent electrochemical performance would help to use these nanocomposites for energy storage applications.
