Advanced two-dimensional (2D) materials with excellent physicochemical properties create huge interest in developing high-energy-density supercapacitors without diminishing their power densities. Herein, a novel bismuthene/antimonene nanocomposite (Biene/Sbene NC) has been employed as an efficient active material to fabricate supercapacitor electrodes with excellent electrochemical performance. As a result, the Biene/Sbene electrode delivers a high specific capacity of 1003.3 C/g at a scan rate of 10 mV/s and an outstanding cycling stability of 87.3% for 10,000 charge−discharge cycles. Moreover, the composite electrode provides the total, outer, and inner capacity of 2857.14, 80, and 2777.14 C/g respectively based on Trasatti analysis and their capacitive and diffusion contributions of 97.2 and 2.8% correspondingly. The hybrid supercapacitor (HSC) has been fabricated by the Biene/Sbene NC cathode and activated carbon (AC) anode which demonstrates a high energy density of 131.44 Wh/kg and a maximum power density of 8262.2 W/kg. In addition, the Biene/Sbene//AC HSC demonstrates practical utilization by illuminating the red light-emitting diodes for 5 min by interconnecting three HSCs in series. This work will stimulate an alternate idea to fabricate electrode materials by utilizing novel 2D materials with excellent physicochemical properties for next-generation energy storage devices.

“…The substantial energy capacity of electrode materials working via surface/bulk Faradaic processes makes them ideal for developing high‐performance HSCs [16] . As a result, the production of hybrid materials as electrode materials, or the fabrication of HSCs configurations comprised of Faradaic and non‐Faradaic electrode materials, has emerged as the most distinct and obvious strategy [17–26] . A HSC with two distinct (asymmetric) electrodes working via Faradaic and non‐Faradaic processes is a very good strategy for combining high power density (non‐Faradaic) and high specific energy (Faradaic) in a single device [16,27] .…”

Due to advancements in technology, the energy demand is becoming more intense with time. The rapid fossil fuels consumption and environmental concerns triggered intensive research for alternative renewable energy resources, including sunlight and wind. Yet, due to their time‐dependent operations, significant electric energy storage systems are required to store substantial energy. In this regard, electrochemical energy storage devices, like batteries and supercapacitors (SCs), have recently attracted much research attention. Recent developments in SCs demonstrated that hybrid SCs (HSCs), which combine the excellent properties of batteries and SCs, increase the specific energy, specific power, specific capacitance, and life span. Carbonaceous and redox‐active materials have been explored as efficient electrode materials for applications in HSCs, ultimately enhancing their electrochemical performances. The HSCs performance significantly depends on the porosity, specific surface area, and conductivity of the electrode materials. This review article gives an overview of recent advances in developing HSCs with high specific power, specific energy, and long cyclic‐life. The fabrication of various HSCs materials using carbonaceous and redox‐active nanoarchitectures and their characterization are explored in‐depth, including electrode development, basic principles, and device engineering. A proper investigation has been conducted regarding state‐of‐the‐art materials as HSC electrodes. This review focuses on the most up‐to‐date, cutting‐edge, electrode materials for HSCs and their performance. The possibilities for novel electrode materials and their impact on the HSCs performance for future energy storage are also discussed.

“…Conductive Materials Selection: Nanostructured carbon materials (such as carbon nanotubes (CNTs), [25,26] graphene (G), [27] graphene oxide (GO), [28,29] and reduced graphene oxide (rGO) [30,31] ) with sp2 hybridized carbon atoms have been widely used to optimize the electrical conductivity of MOFs due to their striking electrical conductivity, excellent mechanical strength, and outstanding chemical stability. There are three major paths for charge transport in the composites of MOFs and nanostructured carbon materials (MOFs-carbon): 1) band conduction or variable range hopping within each carbon filler, 2) electron/hole tunneling between two carbon filler separated by a relatively thin layer of dielectric MOF material, and 3) electron/hole hops through the MOF, if a redox active metals/ligands are used.…”

inherent disadvantage of unstable output, which means electrochemical energy storage and conversion devices are essential for storing and utilizing these energies at any time. [6] Supercapacitors (SCs), lithium-ion batteries (LIBs), lithium-sulfur (Li-S) batteries, and electrochemical water splitting can efficiently convert electricity into chemical energy for storage and thus have received extensive attention. [7] The performance of the energy storage devices mainly depends on the electrode materials and the performance of energy conversion devices mainly depends on catalysts. Therefore, the development of high-performance electrode materials and electrocatalysts is crucial.Metal-organic frameworks (MOFs), also known as porous coordination polymers, are a new type of porous crystalline material. [8] Obtained by bridging metal ions or clusters and organic ligands via well-defined coordination bonds, MOFs possess unique structures with ultrahigh specific surface area, tunable composition, adjustable pore structure, and abundant exposed active sites, exhibiting significant potential for applications in gas storage and separation, catalysis, sensing, and energy storage. [9,10] The regular open pore structures of MOFs enable them to effectively contact electrolytes and alleviate volume expansion during charging and discharging when serving as electrodes. Besides, the abundant exposed active sites and the ultrahigh specific surface area of MOFs can meet the performance requirements of electrocatalysts for water splitting and electrode materials for SCs and LIBs, the plentiful polar sites and the complex pore structure of MOFs can effectively adsorb polysulfides as sulfur host. [11,12] Therefore, in recent years, great efforts have been devoted to the use MOFs as electrode materials for supercapacitors, anode materials for LIBs, sulfur hosts for Li-S batteries, and electrocatalysts for water splitting.The pristine MOFs possess numerous electrochemically active sites, which are almost fully accessible due to the regular pore structures. However, MOFs are usually composed of metal ions and redox-inactive organic ligands, lack free charge carriers, and charge transport paths, and thus are mostly electrically insulating, meaning that only the part in contact with current collectors or conductive additives can gain electrons to participate in the reaction, resulting in low utilization of Metal-organic frameworks (MOFs) with diverse composition, tunable structure, and unique physicochemical properties have emerged as promising materials in various fields. The tunable pore structure, abundant active sites, and ultrahigh specific surface area can facilitate mass transport and provide outstanding capacity, making MOFs an ideal active material for electrochemical energy storage and conversion. However, the poor electrical conductivity of pristine MOFs severely limits their applications in electrochemistry. Developing conductive MOFs has proved to be an effective solution to this problem. This review focuses on the design and syn...
