“…Li-ion capacitors (LICs) are made up of a capacitor-type cathode, one battery-type anode, and one appropriate electrolyte [ 15 , 69 , 70 , 71 , 72 , 73 , 74 ]. They rely on the surface reaction of the cathode and the lithiation/electrolysis of the anode to achieve energy storage and conversion [ 14 , 16 , 17 , 18 ]. Owning to the higher power density together with the longer cycle life than those of Li-ion batteries, as well as higher energy density than that of supercapacitors, LICs are regarded to be one of the most prospective electrochemical energy storage devices.…”

“…When compared to rechargeable batteries, supercapacitors exhibit quicker charging and discharging (supercapacitors: 1–10 s vs. battery: 0.5–5 h), higher power density (supercapacitors: 500–10,000 W kg −1 vs. battery < 1000 W kg −1 ), remarkable longer life (supercapacitors > 500,000 h vs. battery: 500–1000 h), together with safer operation [ 2 , 11 , 12 , 13 ]. However, the low energy density of supercapacitors (supercapacitors: 1–10 W h kg −1 vs. battery: 10–100 W h kg −1 ) is a major challenge to the further development of supercapacitors [ 2 , 11 , 14 , 15 , 16 , 17 , 18 ]. To overcome this, most studies have focused on developing high-performance supercapacitor electrode materials.…”

“…Asymmetric supercapacitors combine two electrode materials with a good potential window [ 23 , 24 ]. As a new type of supercapacitor, hybrid supercapacitors are composed of battery-type negatives (electrochemical insertion or conversion) and capacitive positives (physical adsorption) and have many characteristics of supercapacitors [ 14 , 15 , 16 , 17 , 18 ].…”

Supercapacitors have gained e wide attention because of high power density, fast charging and discharging, as well as good cycle performance. Recently, expanded graphite (EG) has been widely investigated as an effective electrode material for supercapacitors owing to its excellent physical, chemical, electrical, and mechanical properties. Based on charge storage mechanism, supercapacitors have been divided into symmetric, asymmetric, and hybrid supercapacitors. Here, we review the study progress of EG-based materials to be electrode materials. Furthermore, we discuss the application prospects and challenges of EG-based materials in supercapacitors.

“…23 In addition, contamination of surfactants and intercalation residues formed due to various synthetic techniques has not been addressed effectively. 173 Second, strong electrolytes with higher ion conductivity and large potential windows are needed to achieve high energy density, apart from novel electrode materials. Third, the energy density of a supercapacitor device also depends on the weight/volume of the electroactive materials and nonactive material substrates.…”

Emergence of Novel 2D Materials for High-Performance Supercapacitor Electrode Applications: A Brief Review

View full text Add to dashboard Cite

Energy storage and production is one of the significant issues of the 21st century, motivating the search for new materials for energy storage devices. Supercapacitors (SCs) play a prominent role among the class of energy storage devices and conversion systems since they provide greater specific capacitance, high power density, longer life span, fast charge–discharge rate, excellent circulation feature, low cost, and are safe to use. The selection of electrode material has great importance in the performance of the supercapacitor. Two-dimensional (2D) layered nanomaterials gained much interest in the fabrication of electrode materials due to their unique physicochemical properties. The current review explores the synthesis and application of novel 2D materials, such as graphene, MXene, transition metal dichalcogenides (TMDs), hexagonal boron nitride (h-BN), carbon nitrides, metal oxides/hydroxides, and black phosphorus (BP), as supercapacitor electrodes in detail.

“…The CV curves show an increase in peak currents with respect to scan rates, and the sharp redox peaks are maintained even at a high scan rate of the device which confirms the high rate capability of the device. The galvanostatic charge−discharge curves at different current densities revealed the discharge capacities of 42,38,35,33,31,28, and 27 mAh g −1 at current rates of 0.2, 0.5, 1, 2, 5, and 10 A g −1 , respectively. The device exhibited a high energy density of 56 Wh kg −1 at a power density of 39 W kg −1 as well as an extraordinary energy density of 31 Wh kg −1 at a high power density of 4096 W kg −1 .…”

The hybrid supercapacitor is appealing for commercial applications which have the aptitude to supply high energy density without compromising other supercapacitor properties. The Review is the complete insight of a reported Na + -and Zn + -based hybrid supercapacitor with the principle of the working mechanism. The combination of different semiconductor-based electrodes as the anode or cathode has been presented so researchers can update the progress of the sodium-ion-based hybrid supercapacitor (Na-HSC). In pursuit of replacing the activated carbon (AC)-based electrode due to its limited capacitance which results from an imbalance between the cathode and anode, we provide this Review with tables, figures, and their comparative studies. Society is moving toward smart electronic and hybrid devices that require flexibility, resilience, and high safety as people closely interact with these devices. The zinc ion hybrid supercapacitor (Zn-HSCs) is a comprehensive solution to toxic and explosive sodium-ion and lithium-ion devices. This Review represents recent reported metal oxides, chalcogenides, ceramics, MXenes, and carbon-based materials used for Zn-HSCs. Additionally, the hybrid capacitors with flexibility and the lightweight micro-supercapacitors have been studied and presented along with their challenges for pragmatic usage.
