“…These differences suggest that boron-modified The results of numerical simulation are in qualitative agreement with the results of the experimental work. Indeed, decorating CNTs with boron-containing compounds leads to an increase in the total capacity of the electrodes, which is confirmed by experimental studies [22,34]. It was also experimentally shown in [21] that boron-modified CNTs have lower ohmic resistance, charge transfer resistance, and resistance to ion transfer in the electrolyte than pure CNTs.…”

We explore the quantum capacitance, stability, and electronic properties of single-walled carbon nanotubes decorated with B12 icosahedral boron clusters by first-principle calculation methods implemented in the SIESTA code. After the optimization of the built supercells, the B12 clusters formed bonds with the walls of the carbon nanotubes and demonstrated metallic properties in all cases. The network of carbon nanotubes with its large area and branched surface is able to increase the capacity of the electric double-layer capacity, but the low quantum capacity of each nanotube in this network limits its application in supercapacitors. We found that the addition of boron clusters to both the outer and inner walls increased the quantum capacitance of carbon nanotubes. The calculation of the transmission function near the Fermi energy showed an increase in the conductivity of supercells. It was also found that an increase in the concentration of boron clusters in the structure led to a decrease in the heat of formation that positively affects the stability of supercells. The calculation of the specific charge density showed that with an increase in the boron concentration, the considered material demonstrated the properties of an asymmetric electrode.

“…The supercapacitors based on CNT and boron nitride are recognized as one of the most effective: its electrode retains 98% of its original total capacity after 10,000 charge/discharge cycles [22]. Thus, numerous modern scientific studies, both experimental and theoretical, prove the relevance and prospects of EDLC electrode materials.…”

“…However, due to surface charges, 2D h-BN sheets tend to agglomerate; therefore, hybridization with other nanostructures or conducting polymers is required. Recently, hydroxyl (-OH) functionalized 2D h-BN/polyaniline (PANI)/CNT nanohybrid was employed as an electrode [107]. It was shown that 2D h-BN stabilizes PANI in the system via a Coulombic interaction.…”

The prominence of two-dimensional hexagonal boron nitride (2D h-BN) nanomaterials in the energy industry has recently grown rapidly due to their broad applications in newly developed energy systems. This was necessitated as a response to the demand for mechanically and chemically stable platforms with superior thermal conductivity for incorporation in next-generation energy devices. Conventionally, the electrical insulation and surface inertness of 2D h-BN limited their large integration in the energy industry. However, progress on surface modification, doping, tailoring the edge chemistry, and hybridization with other nanomaterials paved the way to go beyond those conventional characteristics. The current application range, from various energy conversion methods (e.g., thermoelectrics) to energy storage (e.g., batteries), demonstrates the versatility of 2D h-BN nanomaterials for the future energy industry. In this review, the most recent research breakthroughs on 2D h-BN nanomaterials used in energy-based applications are discussed, and future opportunities and challenges are assessed.

“…The resultant nanocomposite exhibited a specific capacitance of 515 F•g −1 as well as an E d of 46 Wh•kg −1 in a three-electrode system.After 10,000 cycles, 98% of the capacitance remained. The nanohybrid ternary composite has also been used as electrode material in an ASSC, which provides an excellent E d of 62 Wh•kg −1 and capacitance retention about 91% after 5000 cycles [455]. In another study, a ternary nanocomposite was synthesized through the hydrothermal method using rGO, exfoliated BN NSs, and Ni(OH BP is another strong candidate that is comprised of phosphorene layers connected by the Van der Waals interaction [457].…”

Electrode Materials for Supercapacitors: A Review of Recent Advances

2020

View full text Add to dashboard Cite

The advanced electrochemical properties, such as high energy density, fast charge–discharge rates, excellent cyclic stability, and specific capacitance, make supercapacitor a fascinating electronic device. During recent decades, a significant amount of research has been dedicated to enhancing the electrochemical performance of the supercapacitors through the development of novel electrode materials. In addition to highlighting the charge storage mechanism of the three main categories of supercapacitors, including the electric double-layer capacitors (EDLCs), pseudocapacitors, and the hybrid supercapacitors, this review describes the insights of the recent electrode materials (including, carbon-based materials, metal oxide/hydroxide-based materials, and conducting polymer-based materials, 2D materials). The nanocomposites offer larger SSA, shorter ion/electron diffusion paths, thus improving the specific capacitance of supercapacitors (SCs). Besides, the incorporation of the redox-active small molecules and bio-derived functional groups displayed a significant effect on the electrochemical properties of electrode materials. These advanced properties provide a vast range of potential for the electrode materials to be utilized in different applications such as in wearable/portable/electronic devices such as all-solid-state supercapacitors, transparent/flexible supercapacitors, and asymmetric hybrid supercapacitors.
