Article
Full-text available
Although numerous methods have been widely used to prepare nickel hydroxide materials, there is still a demand for lowering the required heating time, temperature, and cost with maintaining a high-quality nanomaterial for electrochemical energy storage. In this research, we study the relationship between microwave-assisted heating parameters and ma...
Article
Aqueous zinc batteries are among the most promising large-scale energy storage technologies but their practical application is hindered by the low redox reversibility of Zn anode in aqueous electrolytes. In this work, an indium-coated carbon-zinc composite (ICZ) anode is demonstrated with outstanding cyclic stability in classic aqueous zinc sulfate...

The demand for supercapacitors has been high during the integration of renewable energy devices into the electrical grid. Although activated carbon materials have been widely utilized as supercapacitor electrodes, the need for economic and sustainable processes to extract and activate carbon nanomaterials is still crucial. In this work, the biomass...
Article
Full-text available
Supercapacitors have been considered as one of the main energy storage devices. Recently, electrospun nanofibers have served as promising supercapacitor electrodes because of their high surface area, high porosity, flexibility, and resistance to aggregation. Here, we investigate the effects of electrospinning parameters and nickel precursors on the...

An electrochemical zinc ion capacitor (ZIC) is a hybrid supercapacitor composed of a porous carbon cathode and a zinc anode. Based on the low‐cost features of carbon and zinc metal, ZIC is a potential candidate for safe, high‐power, and low‐cost energy storage applications. ZICs have gained tremendous attention in recent years. However, the low ene...

Oil fly ash has been reported to be suitable for producing low-cost carbon nanotubes (CNTs). These CNTs exhibit zigzag curved walls with an almost bamboo-like structure. Owing to this structure, these CNTs exhibit very low thermal conductivity as compared to other graphitic carbon materials. They also exhibit relatively low electrical conductivity....

A poly(ortho toluidine-co-aniline)/SiO2 nanocomposite electrode (Poly(oT-co-ANI)/SiO2) was fabricated in one step using electrodeposition polymerization. The polymer layer was characterized using UV–Vis spectroscopy, FTIR spectroscopy, and SEM/EDX. The electrochemical performance of the nanocomposite electrode was tested in 1 M H2SO4\documentclass[...
Article
Aqueous electrochemical zinc ion capacitors (ZICs) are promising next‐generation energy storage devices because of their high safety, inexpensive raw materials, and long cycle life. Herein, an aqueous ZIC with superior performance is fabricated by employing an oxygen‐rich porous carbon cathode. Excellent capacitance and energy density are obtained...
Article
Here we introduce an ecological facile method to grow heterogeneous copper oxide (CuxO) nanocomposites on a Cu mesh using spinach leaf extract. After annealing at different temperatures, morphological and structural characterizations revealed that samples annealed at 300 °C comprise the highest Cu⁺/Cu²⁺ ratio and reveal the most porous structure. S...
Article
Supercapacitors (SCs) have experienced a significant increase in research activity and commercialization during the past few decades. As the primary and most important electrode active material for commercial SCs, porous carbon is produced at an industrial‐scale through traditional carbonization‐activation strategies. Nevertheless, commercial porou...
Article
In this work, we report a green, nontoxic, no-residue method for degradation of methylene blue (MB) using Cu-Cu2O films prepared with spinach leaves extract. The photocatalytic activity for two composite films with different copper concentrations, specifically 0.01M and 0.05M, was investigated under natural outdoor light which has an average irradi...
Article

In this project, Ni–Cu–OH and Ni–Co–OH ternary electrodes have been prepared. Different Ni:Cu and Ni:Co ratios were deposited by chemical bath deposition (CBD) at room temperature on carbon microfibers. Since Ni(OH)2 is notorious for poor cycling stability, the goal of the work was to determine if doping with Cu or Co could improve Ni(OH)2 cycling...
Article
Metal hydroxide based microfabricated pseudocapacitors with impressive volumetric stack capacitance and energy density are demonstrated. A combination of top-down photolithographic process and bottom-up chemical synthesis is employed to fabricate the micro-pseudocapacitors (μ-pseudocapacitors). The resulting Ni(OH)2-based devices show several excel...
Article
Porous cobalt sulfide (Co9S8) nanostructures with tunable morphology, but identical crystal phase and composition, have been directly nucleated over carbon fiber and evaluated as electrodes for asymmetric hybrid supercapacitors. As the morphology is changed from two-dimensional (2D) nanoflakes to 3D octahedra, dramatic changes in supercapacitor per...
Article
A novel supercapacitor electrode structure has been developed in which a uniform and conformal coating of nanostructured Ni(OH)2 flakes on carbon microfibers is deposited in situ by a simple chemical bath deposition process at room temperature. The microfibers conformally coated with Ni(OH)2 nanoflakes exhibit five times higher specific capacitance...
