Special Issue Information

Dear Colleagues,

Keeping eye on increasing trend in world energy consumption, someday the natural resources will bound to run out. Therefor it is necessary to establish a sustainable and innovative solutions to store energy. In recent years, nanocomposites made up off (Graphene/metal oxide & conducting polymer) have attracted a great deal of attention in energy storage and conversion devices. The performance of the devices strongly relies on the structure and properties of the component materials.

This special issue covers the significance of advanced nanomaterials and nanocomposites for sustainable energy conversion and storage technologies for Supercapacitor application by creating new materials (such as Graphene, MXene, metal–organic frameworks (MOFs), transition metal dichalcogenides (TMDs), covalent organic frameworks (COFs), metal nitrides (MNs), black phosphorus (BP), perovskite) and innovative structure ( nanowire, nanosheets & 3D nanofoams). Furthermore, the special issue will also address the synthesis, characterization and fundamental understanding of capacitive behaviors at molecular and nano scales of coposite materials to improve the device performance for a large variety of potential applications, including consumer electronics, wearable devices, hybrid electric vehicles etc. This Special Issue of “Nanocomposites for Supercapacitor application: (Synthesis, Characterization & performance) ”, aims at collecting a compilation of articles, which cover research articles, reviews and communications, with topics areas focused on the development of the state-of-the-art nanocomposites to tackle energy storage and conversion related issues.

This paper presents a novel ultrasonic-assisted electrodeposition process of Mn-doped NiCo2O4 onto a commercial nickel foam in a neutral electroplating bath (pH = 7.0) under an ultrasonic power of 1.2 V and 100 W. Different sample properties were studied based on their crystallinity through X-ray diffraction (XRD), morphology was studied through scanning electron microscopy (SEM), and photodegradation was studied through ultraviolet–visible (UV–Vis) spectrophotometry. Based on the XRD results, the dominant crystallite phase obtained was shown to be a pure single NiCo2O4 phase. The optical properties of the photocatalytic film showed a range of energy band gaps between 1.72 and 1.73 eV from the absorption spectrum. The surface hydroxyl groups on the catalytic surface of the Mn-doped NiCo2O4 thin films showed significant improvements in removing methyl red via photodegradation, achieving 88% degradation in 60 min, which was approximately 1.6 times higher than that of pure NiCo2O4 thin films. The maximum hydrogen rate of the composite films under 100 mW/cm2 illumination was 38 μmol/cm2 with a +3.5 V external potential. The electrochemical performance test also showed a high capacity retention rate (96% after 5000 charge–discharge cycles), high capacity (260 Fg−1), and low intrinsic resistance (0.8 Ω). This work concludes that the Mn-doped NiCo2O4 hybrid with oxygen-poor conditions (oxygen vacancies) is a promising composite electrode candidate for methyl red removal, hydrogen evolution, and high-performance hybrid supercapacitor applications.

This work reports the preparation and testing of a composite material composed of α-Manganese dioxide (α-MnO2) coated with polyaniline (PANI) and reduced graphene oxide (rGO) for supercapacitor application. The structure and morphology of the materials were characterized by using X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) and Raman spectroscopy. The electrochemical performances of the materials were investigated by using cyclic voltammetry (CV), Galvanostatic charge–discharge (GCD), cyclic stability and electrochemical impedance spectroscopy (EIS). The α-MnO2-coated PANI/rGO nanocomposite exhibited a specific capacitance of 261 F g−1 at the scan rate of 5 mV s−1 with 75% capacitance retention after 2000 cycles at 5 A g−1. It showed a specific energy of 11 W h kg−1 and specific power of 1250 W kg−1. Full article

Supercapacitors are one of the promising devices for the accumulation and storage of electrical energy. The purpose of this study is to develop a synthesis and modification method of carbon material to improve the electrochemical characteristics of a supercapacitor. In the proposed study, by varying the sequence and parameters of the processes of carbonization, mechanoactivation and thermochemical activation, the conditions for obtaining nanoporous carbon with a specific surface area of 2200 (±50) m2/g from walnut shells (WSs) are optimized. In addition, to increase the electrochemical efficiency of the electrode material, the resulting nanoporous carbon was modified with nickel oxide (NiO) nanoparticles by the thermochemical method. It is shown that the modification with nickel oxide nanoparticles makes it possible to increase the specific capacitance of the supercapacitor electrode by 16% compared to the original unmodified nanoporous carbon material.

Supercapacitors have gained significant attention as energy storage devices due to their high specific power, fast charge–discharge rate and extended cycling stability. Recent research focuses on the search for new electrode materials to enhance the specific capacitance of supercapacitors. Conducting polymers (CPs) and metal oxides (MOs) are being extensively tested as electrode materials in supercapacitors. CPs have poor cycling stability and low mechanical strength but are easy to process, while MOs exhibit easy availability, variable oxidation states and possess high specific capacitance, but they are somewhat difficult to process. Therefore, combining both (CP) and (MO) in a composite offers better results for the electrochemical performance of supercapacitors. This review mainly focuses on the discussion of CP/MO based nanocomposites recently reported for supercapacitor applications. The collective information presented in this report will provide researchers a view into the latest developments in this field. The continued research on this topic will reveal further potential applications of CP/MO composites. Full article
