Rational Design of Asymmetric Spinel/Defect Spinel (ZnMn₂O₄/Cu_1.5Mn_1.5O₄) Nanocomposite-Based Supercapacitor Devices for Efficient Energy Storage with Improved Cycle Stability

ACS Applied Energy Materials, Journal Year: 2024, Volume and Issue: 7(17), P. 7205 - 7219

Published: Aug. 19, 2024

The increasing global demand for energy solutions has created the necessity innovative nanocomposite materials efficient storage applications. This urgency is driving significant advancements in technologies, raising hope future of sectors. Supercapacitors (SCs), high-performance electrochemical devices, have earned considerable attention to address these challenges. In this article, we demonstrated a cost-effective, easily obtainable trimetallic spinel/defect-spinel oxide ZnMn2O4/Cu1.5Mn1.5O4 (ZMO/CMO) through facile one-step solvothermal synthesis process. exceptional charge capabilities. mechanism was established by using Dunn's method, which reveals diffusive nature electrode material. ZMO/CMO exhibits an impressive specific capacitance 468.1 F/g at 0.5 A/g, with 84% capacity retention even after 20000 cycles, attributed oxygen vacancies within defect spinel structure. Moreover, fabricated asymmetric device utilizing as cathode and activated carbon (AC) anode. attained density 48.1Wh/kg power 700 W/kg excellent cycling stability, mentioned before. Furthermore, our study featured its ability standard LED light.

Preparation of new, stable and efficient electroactive nanocomposites for the fabrication an advanced supercapacitor device is a hot spot research arena owing to their huge demand in energy storage applications. In this study, spinel tin manganese oxide, SnMn2O4 (SMO) was prepared then on conjoining with multi-walled carbon nanotube (MWCNT), 3 types oxide fused (SnMn2O4@MWCNT) were by simple ultra-sonication process. The study forecasts that ultrasonication vital designing high storage. order improve redox characteristics SMO, load charge transport matrix (MWCNT) fixed as 2.5%, 5.0% 7.5%, yielding SnMn2O4@MWCNT (SMMCNCs-1, SMMCNCs-2 SMMCNCs-3) respectively. These three thoroughly characterized through spectroscopic microscopic techniques. To investigate performance, these electrodes studied using Cyclic voltammetry (CV), Galvanostatic discharge (GCD) Electrochemical Impedance spectroscopy (EIS) under three-electrode assembly. Based obtained results, among electrodes, has produced highest specific capacitance, Csp 1730 Fg-1 (264 mAh g-1) at 1 Ag-1, retaining 92.31% capacitance up 1000 cycles. reversible faradaic characteristics, cyclic stability, used fabricate Asymmetric (ASCD) activated (AC) anode (SMMCNCs-2//AC). On examining its potential two electrode assembly, it observed delivered Csp, Energy density, E Power P 94.1 Fg-1, 37.7 Wh kg-1 3400 W kg-1, Also, present ASC able illuminate red-light emitting diode. This performance superior than previously reported manganese-based oxides. Thus, optimization promising effective way produce material development devices.
