Supercritical fluid synthesized Cu2ZnSnS4-Polyaniline nanocomposites for supercapacitor application

Textile based energy storage is becoming increasingly popular for smart-textile sensing application while being comfortable and relatively easy to integrate into clothing. In this study, textile fabric was structured in a mesh geometrical configuration by embroidery stitching technology, which provides high flexibility and stability in the fabrication of wearable supercapacitor devices. The output performance of the textile supercapacitor provides specific capacitance, energy density and power density 266.6 Fg−1, 37.027 Whkg−1 and 177 Wkg−1 for silver mesh fabric and 172 Fg−1, 24.583 Whkg−1 and 118.156 Wkg−1 for stainless steel mesh respectively as can be seen by the cyclic voltammogram (CV) curve of the supercapacitor at a scan rate of 10 mV/s. Silver mesh fabric supercapacitor is provided higher output performance as compare to stainless steel mesh fabric and presented capacitance retention stability at 95.4 % after 5000 cycles at a constant current of 0.25 mA. The fabricated textile supercapacitor is able to be charged up to 2.8 V of 3.0 s at constant current of 2.0 mA and able to be lighted up a commercial light-emitting diodes (LEDs). All experimental results indicate that supercapacitors constructed with silver mesh fabric and graphene oxide/manganese dioxide (G-MnO2)/carbon black have the potential to serve as electrode materials and flexible substrate for flexible textile-based supercapacitors. 

Smart-textile supercapacitor for wearable energy storage system

Supercapacitors are a revolutionary type of energy storage device. They must be able to charge and discharge quickly while maintaining a high energy density. A storage material’s cyclic stability is a desirable feature. The type of electrode materials employed for the specific study design affects supercapacitor performance. Manganese dioxide has long been regarded as one of the best and most abundant materials in nature, having a potentially high specific capacitance. They also offer a wider potential range, more electroactivity, and are more environmentally friendly. However, because of its decreased volume expansion and low conductivity, it is difficult to use as a capacitor material. As a result, carbon-based porous films and supports can be employed to produce critical composites to overcome the current shortcoming. These nanoparticle-based materials will have improved electrical conductivity and a large surface area. Graphene oxide (GO) has a high surface area, thermal stability, and porosity. As an electrode material, many types of MnO2/carbon-based materials have been widely used in supercapacitors. Their overall performance is influenced by their construction processes, metal ratios, electrolyte medium, and voltage factors. Microwave technology was chosen as a cost-efficient and effective alternative to expensive and laborious techniques for fabricating MnO2/GO composites. The production procedure of a supercapacitor has been explored in this study using MnO2-GO composite materials. Using the electrochemical deposition process, the nanocomposite materials of MnO2-GO are significantly deposited on the stainless steel (SS) substrate material. Galvanostatic charge-discharge techniques and cyclic voltammetry (CV) analytical methods were used to investigate the storage and cycle ability of supercapacitors. The composite MnO2-GO supercapacitor has a higher electrochemical capacitance based on these findings.

Performance Evaluation of Cyclic Stability and Capacitance of Manganese Oxide Modified Graphene Oxide Nanocomposite for Potential Supercapacitor Applications

A new strategy for supercapacitor formation was carried out in the study using electrodes made of graphene oxide (GO) and manganese dioxide (MnO2) nanocomposites. To the present knowledge, only a few investigations have been carried out concerning the synthesis of GO-MnO2-based nanocomposites and their electrochemical properties, with varying mass ratios, as well as the change in electrochemical properties of their components as MnO2 and GO were tested individually for the enhanced stability and performances. A synthetic method was performed successfully to manufacture MnO2/GO nanocomposites. The findings of the present study show that the composites have a lot of potential as an effective conduction property. A composite of graphene oxide supported manganese dioxide nanocomposites fabricated with the simple soft chemical route. As-prepared nanocomposites can be improved in performance by the interactions between GO and MnO2.

Fabrication of MnO2 Nanocomposite on GO Functionalized with Advanced Electrode Material for Supercapacitors

Study of microstructural, chemical and microhardness characterization of stainless steels

In this study, calcium phosphate-chitosan nanocomposite (CaP-CS NC) was prepared by a convenient and affordable co-precipitation method, and the prepared NC was tested for agriculture application.  Physico-chemicals analyses of the CaP-CS NC were conducted by X-ray diffraction (XRD), scanning electron microscope with energy dispersive X-ray spectroscopy (SEM-EDS), Fourier transform infrared spectroscopy (FTIR), and ultraviolet-visible spectroscopy (UV-Vis) instruments to determine the structural characteristics, surface topology, chemical composition, function group, and optical properties. The XRD pattern of CaP-CS NC revealed that the average crystallite size was 43 nm. The SEM images showed agglomeration of the CaP-CS NC with a rod-like shape. The EDS spectrum of the CaP-CS NC indicated the presence of Ca, P, O, and N elements. FTIR displayed vibrational peaks for the active functional group such as carboxylic (C=O), amines (N-H), hydroxyl (O-H), and alkyne (C-H). Furthermore, the spectrum of CaP-CS NC showed the bending mode of phosphates at 588.37 cm-1 and 508.45 cm-1. The UV-Vis-NIR spectrum of the prepared nanocomposite indicates the anti-reflection properties, which might be useful in solar cell applications to increase the efficiency of the solar cell. In addition, the prepared CaP-CS NC was tested for the plant growth stimulator properties at the lab scale level, wherein it exhibited substantial growth. Accordingly, the current study suggests that the prepared CaP-CS NC could be used as a plant growth promoter.
