Abstract
Researchers have been enthusiastic about developing high-performance electrode materials based on metal chalcogenides for energy storage applications. Herein, we developed cupric ion-containing zinc sulfide (ZnS:Cu) nanoplates by using a solvothermal approach. The as-synthesized ZnS:Cu nanoplates electrode was characterized and analyzed by using XRD, SEM, TEM, EDS, and XPS. The binder-free flexible ZnS:Cu nanoplates exhibited excellent specific capacitance of 545 F g-1 at a current density of 1 A g-1. The CV and GCD measurements revealed that the specific capacitance was mainly attributed to the Faradaic redox mechanism. Further, the binder-free flexible ZnS:Cu nanoplates electrode retained 87.4% along with excellent Coulombic efficiency (99%) after 5000 cycles. The binder-free flexible ZnS:Cu nanoplates exhibited excellent conductivity, specific capacitance, and stability which are beneficial in energy storage systems. These findings will also open new horizons amongst material scientists toward the new direction of electrode development.

Abstract
The enticing features of metal molybdates make them an attractive candidate for energy storage systems. This report describes the synthesis of three distinct single-phase bismuth molybdates (Bi2MoxOy; α-Bi2Mo3O12, β-Bi2Mo2O9, and γ-Bi2MoO6) using the gel matrix particle growth method and their application in high-performance asymmetric supercapacitors. The single phase and purity of the synthesized Bi2MoxOy particles were confirmed by X-ray diffraction (XRD) and further verified by Raman analysis. The UV-visible spectra show the electronic and optical behaviours of the as-synthesized α, β, and γ Bi2MoxOy. The morphologies of the as-synthesized three different Bi2MoxOy phases were analysed using scanning electron microscopy (SEM). The particle formation was further investigated by transmission electron microscopy (TEM), and the interplanar spacings of the Bi2MoxOy phases were in accordance with the planes. The surface area and pore volume of the prepared samples were analysed using Brunauer-Emmett-Teller (BET) analysis. The electrochemical properties of the products were confirmed by various tests, including cyclic voltammetry (CV), galvanostatic charge discharge (GCD), and electrochemical impedance spectroscopy (EIS) in 3 M KOH. Among the three phases, α-Bi2Mo3O12 exhibits a huge specific capacitance (Cs) of 714 F g-1 at a current density of 1 A g-1. Furthermore, it displays an admirable cycling stability of 86.55% after 5000 cycles. The chosen α-Bi2Mo3O12 electrode possesses an increased energy density of 47.5 W h kg-1 at 1 A g-1 with a capacitive retention rate of 71.90% at 5 A g-1 after 10 000 cycles. A remarkable electrochemical performance of Bi2Mo3O12 with an exceptional power density of 750 W kg-1 was observed for the prepared asymmetric device. Bismuth molybdate's notable performance indicates that it can be an active material for energy storage applications.

Abstract
Recently, magnesium molybdate materials have attracted scientific attention for application in supercapacitor devices due to advantages like low synthesis cost and good redox reactions. Nevertheless, these materials endure low electrical conductivity leading to inferior electrochemical performance. To eliminate this drawback, we prepare a composite powder containing magnesium molybdate and functionalized carbon nanotubes (MMO/C) using a simple process to improve the supercapacitive properties. The results proved an electrostatic interaction between the two components of the composite powder, which contains 18-30 nm magnesium molybdate nanoparticles. A crystal model related to magnesium molybdate powder (MMO) was simulated, illustrating that MnO6 octahedra are formed next to MoO4 tetrahedra. The mesoporous structure of both powders was confirmed whereas the specific surface area of the MMO was enhanced by 69.9% to 36.86 m2 g-1 in the MMO/C powder with more electroactive sites. The higher electrical conductivity of the MMO/C electrode was proved using electrochemical impedance spectroscopy (EIS) results, with the MMO/C electrode achieving a specific capacitance of 571 F g-1 at 1 A g-1 current density, improved by more than 4.5 times that of the MMO. Furthermore, the rate performance and cycling stability of the MMO/C electrode reached 87% and 85.2%, respectively. Finally, a two-electrode energy storage device (MMO/C//AC) was assembled. It reveals a specific capacitance of 94.7 F g-1, a maximum energy density of 29.6 W h kg-1 at a power density of 660.1 W kg-1, and cycling performance of 84.3% after 2000 cycles. As a result, the resulting data demonstrate that the MMO/C electroactive material has promising abilities in capacitive energy storage systems.

Abstract
Considerable efforts are underway to rationally design and synthesize novel electrode materials for high-performance supercapacitors (SCs). However, the creation of suitable materials with high capacitance remains a big challenge for energy storage devices. Herein, unique three-dimensional (3D) ZnO hexagonal cubes on carbon cloth (ZnO@CC) were synthesized by invoking a facile and economical hydrothermal method. The mesoporous ZnO@CC electrode, by virtue of its high surface area, offers rich electroactive sites for the fast diffusion of electrolyte ions, resulting in the enhancement of the SC’s performance. The ZnO@CC electrode demonstrated a high specific capacitance of 352.5 and 250 F g−1 at 2 and 20 A g−1, respectively. The ZnO@CC electrode revealed a decent stability of 84% over 5000 cycles at 20 A g−1 and an outstanding rate-capability of 71% at a 10-fold high current density with respect to 2 A g−1. Thus, the ZnO@CC electrode demonstrated improved electrochemical performance, signifying that ZnO as is promising candidate for SCs applications.
