With the rapid improvement of the global economy, the role of energy has become even more vital in the 21st century. In this regard, energy storage/conversion devices have become a major, worldwide research focus. In response to this, we have prepared two-dimensional (2D)-hierarchical sheet-like ZnCo2O4 microstructures for supercapacitor applications using a simple hydrothermal method. The 2D-hierarchical sheet-like morphologies with large surface area and smaller thickness enhanced the contact area of active material with the electrolyte, which increased the utilization rate. We investigated the electrochemical performance of sheet-like ZnCo2O4 microstructures while using Cyclic voltammetry (CV), Galvanostatic charge-discharge (GCD), and Electrochemical impedance spectroscopy (EIS) analysis. The electrochemical results demonstrated that the ZnCo2O4 electrode possesses 16.13 mF cm−2 of areal capacitance at 10 µA cm−2 of current density and outstanding cycling performance (170% of capacitance is retained after 1000 cycles at 500 µA cm−2). The high areal capacitance and outstanding cycling performance due to the unique sheet-like morphology of the ZnCo2O4 electrode makes it an excellent candidate for supercapacitor applications.

“…The frequency bands are inversely related to the bond length. Since υ 1 is greater than υ 2 , the dimensions of the octahedron (B-site) are larger than those of the tetrahedron (A-site) [ 3 , 4 ]. As shown in Table 4 , the range of υ 1 band decreases as the Cd 2+ concentration increases, while the υ 2 band remains constant.…”

“…Ferrite materials possessing spinel structures are crucial for basic disciplinary research, particularly in the study of the underlying relationship between crystal structure and magnetic effects [ 1 , 2 ]. The spinel-structured ferrite AFe 2 O 4 has superior structural, magnetic, and dielectric properties [ 3 , 4 , 5 ]. It also has potential applications in areas such as high-density data storage, ferromagnetic fluids, color imaging, high-frequency devices, and drug delivery systems [ 4 , 6 ].…”

“…Spinel ferrite has an Fd-3m space group [ 1 ]; oxygen ions produce a face-centered cubic (fcc) tightly-packed arrangement [ 8 ]. Metal ions occupy tetrahedral (A) or octahedral (B) positions, with oxygen ions as the backbone [ 4 , 23 , 24 ]. The variation of different ions in the tetrahedral or octahedral positions can alter the structural, electrical, magnetic, and catalytic properties of spinel-type ferrite nanomaterials [ 17 , 25 , 26 ].…”

CdxNi0.5−xCu0.2Zn0.3Fe2O4 (0 ≤ x ≤ 0.50) ferrite with a spinel structure was prepared using the sol–gel self-propagation method. The effects of Cd2+ doping on the structure, morphology, dielectric, and magnetic properties of Ni–Cu–Zn ferrite were examined using XRD, SEM, EDX, FTIR, MPMS, and dielectric tests. The cubic spinel structure was verified by XRD and FTIR analyses. The crystallite size and particle size information of the samples were obtained with XRD and SEM analysis. The sample particle size belonged to a class of nanoscale materials with a particle size range of 1–100 nm. The minor difference between the grain size and particle size indicated that the sample nanoparticles were composed of numerous microcrystals. The EDX spectra indicated that the samples contained all stoichiometric elements. MPMS was used to measure the hysteresis lines of the samples. According to the hysteresis line, the saturation magnetization intensity (Ms), coercivity (Hc), and magnetic moment (μB) of the sample increased and then decreased with the increase in cadmium concentration. The magnetization strength (Ms) is between 4–67 emu/g, and the coercivity (Hc) is between 9–46 Oe. The curves of the real part of the dielectric constant (ε′), the imaginary part of the dielectric constant (ε″), and the loss factor (tanδ) with frequency were measured in the frequency range 100 Hz–100 kHz by means of an impedance analyzer. The complex modulus spectrum was analyzed to understand the dynamics of the conduction process.
