“…The deposition of Fe–Co–Ni with 400 pulse repetitions results in the formation of a distinct layer on top of the existing deposited layer, as shown in Figure c,d. For 700 pulses, a second layer grows over the surface although cracks are noticeable owing to gas and electrolyte diffusion during the deposition process (Figure e,f) . This leads to the exposure of the underlying layer.…”

The utility of supercapacitors in various applications has recently received significant attention owing to the cognizance of high electrochemical activity of various combinations of ternary metal compounds. In this paper, we present a strategy for utilizing Fe−Co−Ni as an electrode material in supercapacitors. To enhance the electrochemical performance of the proposed ternary metal compound, we implemented controlled pulse deposition during the electrochemical process and analyzed the structural characteristics of the deposited Fe−Co−Ni. Distinct structural variations were observed based on the waveform and number of pulse repetitions employed during the manufacturing process. The specific capacitance of the ternary metal compound reached a maximum of 432.3 F g −1 at a current density of 0.1 A g −1 when 700 pulses were applied. In addition, it exhibited a capacitance retention rate of 72% at 1.5 A g −1 , with excellent cyclic stability, retaining 81% of its initial capacitance after 10,000 cycles. Our findings highlight the potential of this innovative electrochemical plating strategy for practical energy storage devices.

Correlation among morphological, structural and hardness characteristics of electrodeposited copper coatings is presented in this review paper. Cu coatings were produced applying constant galvanostatic (DC) and pulsating current (PC) regimes on hard silicon (Si(111)) and brass substrates. The parameters of the electrochemical deposition which include the kinds of electrolyte and cathode, the coating thickness and the electrolyte stirring, as well as the parameters defining PC regime, such as the average current density and the current density amplitude, were analyzed. Morphology and structure of Cu coatings were examined by scanning electron microscope (SEM), atomic force microscope (AFM) and by X-ray diffraction (XRD), while hardness was examined by Vickers microindentation. The coatings of Cu on both Si(111) and brass cathodes belong to “soft film (coating) on hard substrate” composite hardness system, and the Chicot–Lesage (C–L) composite hardness model was applied to estimate a hardness of the Cu coatings. Analyzing the examined parameters and regimes of electrodeposition, the critical relative indentation depth (RID)c of 0.14 has been defined by the C–L model. Based on done analyses, it is shown that this RID value, separating a zone where measured hardness corresponds to the coating hardness and a zone where it is necessary to apply the C–L model to determine an absolute hardness of the Cu coatings, has an universal character for the electrolytically produced Cu coatings on Si(111) and brass substrates.

“…Copper-graphene composites, produced through many different methods, succeeded in enhancing the physical and mechanical properties of the composite [ 12 ]. Electroplated Cu-Gr coatings have already been produced to improve the pure copper characteristics; pulsed processes, in addition, can improve the morphological features of the composite coatings and, therefore, their performance.…”

Study on Pulse-Reverse Electroplating Process for the Manufacturing of a Graphene-Based Coating

This work investigates the feasibility of increasing the electric conductivity of an AA1370 aluminium wire by using pulse-reverse electrodeposition to realize Cu-Graphene composite coating. The graphene adopted was in the form of nanoplates (GnP). To study the effects of plating parameters, a 23 factorial plan was developed and tested. During the tests, the following process parameters were varied: the current density, the frequency and the duty cycle. The ANalysis Of VAriance (ANOVA)) was adopted to evaluate their influence on the coated wires’ morphology and electrical conductivity resistance. The results show that all the tested conditions allow good compactness to the coating, and the amount of graphene is well incorporated within the microstructure of the copper deposit. In addition, in the best conditions, the electrical resistivity decreases up to 3.4% than the uncoated aluminum.
