“…The supercapacitor electrodes made from it show 15.3 μF/ cm 2 specific capacitance at 40 mA/g, which is much larger than that of pristine ACs (Umezawa et al, 2021). Mandal et al (2021) prepared a novel composite of AC/MWCNTs-ZnFe 2 O 4 , which exhibit 613 F/g specific capacitance at 5 mV/s scan rate, and after 10,000 cycles, 91% of the capacitance can be retained. Wulandari et al (2021) used CaCl 2 as an active agent to prepare AC from fruit bunches, after carbonization and activation processes, the product was further modified with 1 mol/L nitric acid (HNO 3 ).…”

“…On the other hand, doping of heteroatoms (e.g., O, N, F, S, B, P and metallic atoms into carbon skeleton will often adjust carbonaceous materials' wettability, electroconductibility and capacitance. As shown in Supplementary Figures S7, S8, those surface functionalization can be either derived from heteroatoms containing precursors or achieved through post-treatment/ activation process (Teimuri-Mofrad et al, 2022;Lachawiec et al, 2005;Maldonado-Hódar et al, 2000;Ji et al, 2009;Ramirez et al, 2021;Liu et al, 2017;Qin et al, 2009;Mei, 2022;Ping et al, 2016;Zhai et al, 2021;Hoa et al, 2021;Chen et al, 2021;Cao et al, 2021;Zhou et al, 2021;Wang and Pumera, 2016;Mousavi-Khoshdel et al, 2016;Mousavi-Khoshdel and Targholi, 2015;Silva et al, 2020;Song et al, 2018;Morteza et al, 2015;Kolosov and Glukhova, 2021a;Kolosov and Glukhova, 2021b;Song et al, 2021c;Vermisoglou et al, 2021;Tong et al, 2021;Chakrabarty et al, 2021;Liu et al, 2022;Paul1 and Roy, 2021;Basivi et al, 2021;Zhang et al, 2019;Zhai et al, 2011;Rashidi and Yusup, 2020;Yang and Zhou, 2017;Arango et al, 2018;Umezawa et al, 2021;Mandal et al, 2021;…”

Supercapacitors became more and more important recently in the area of energy storage and conversion. Their large power deliveries abilities, high stability and environmental friendliness characteristics draw tremendous attention in high-power applications such as public transit networks. Carbonaceous materials with unique surface and electrochemical properties were widely used in supercapacitors as electrode materials. This review focuses on the developments in supercapacitor electrodes made from carbonaceous materials recently, their working principle and evaluation parameters were summarized briefly. The preparation methods and electrochemical properties of different carbonaceous materials were compared and classified. It was found that the surface situation (e.g., porous structure, hydrophilic) of carbonaceous materials strongly affect the electrochemical performances of supercapacitor. So far, active carbons would be the most applicable carbonaceous electrode materials owing to their good chemical stability and conductivity, extensive accessibility inexpensiveness. But their energy densities still fall behind practical demands. Both theoretical calculations and experimental studies show that surface modification and doping of carbonaceous materials can not only optimize their pore size, structure, conductivity and surface properties, but also can introduce extra pseudocapacitance into these materials. Considering global environmental pollution and energy shortage problems nowadays, we sincerely suggested that future work should focus on domestic, medical and industrial wastes residues derived carbonaceous materials and scaled production process such as reactors and exhaust gas treatment.

In recent years, the development of energy storage devices has received much attention due to the increasing demand for renewable energy. Supercapacitors (SCs) have attracted considerable attention among various energy storage devices due to their high specific capacity, high power density, long cycle life, economic efficiency, environmental friendliness, high safety, and fast charge/discharge rates. SCs are devices that can store large amounts of electrical energy and release it quickly, making them ideal for use in a wide range of applications. They are often used in conjunction with batteries to provide a power boost when needed and can also be used as a standalone power source. They can be used in various potential applications, such as portable equipment, smart electronic systems, electric vehicles, and grid energy storage systems. There are a variety of materials that have been studied for use as SC electrodes, each with its advantages and limitations. The electrode material must have a high surface area to volume ratio to enable high energy storage densities. Additionally, the electrode material must be highly conductive to enable efficient charge transfer. Over the past several years, several novel materials have been developed which can be used to improve the capacitance of the SCs. This article reviews three types of SCs: electrochemical double-layer capacitors (EDLCs), pseudocapacitors, and hybrid supercapacitors, their respective development, energy storage mechanisms, and the latest research progress in material preparation and modification. In addition, it proposes potentially feasible solutions to the problems encountered during the development of supercapacitors and looks forward to the future development direction of SCs.

“…As a typical binary transition metal oxide, ZnFe 2 O 4 gained much attention due to its high theoretical specific capacitance (~2600 F g −1 ), but is still restricted by poor conductivity and severe agglomeration during charge and discharge process, causing low specific capacitance and cycle life [ 19 , 20 ]. Numerous studies have confirmed that synthesizing composites with carbonaceous material is an effective way to enhance the capacitance and lifespan of ZnFe 2 O 4 for supercapacitors [ 21 , 22 , 23 , 24 ]. Due to the superior electrical conductivity and large theoretical specific surface area, graphene is the perfect candidate for dispersed nanoparticles.…”

As a typical binary transition metal oxide, ZnFe2O4 has attracted considerable attention for supercapacitor electrodes due to its high theoretical specific capacitance. However, the reported synthesis processes of ZnFe2O4 are complicated and ZnFe2O4 nanoparticles are easily agglomerated, leading to poor cycle life and unfavorable capacity. Herein, a facile microwave hydrothermal process was used to prepare ZnFe2O4/reduced graphene oxide (rGO) nanocomposites in this work. The influence of rGO content on the morphology, structure, and electrochemical performance of ZnFe2O4/rGO nanocomposites was systematically investigated. Due to the uniform distribution of ZnFe2O4 nanoparticles on the rGO surface and the high specific surface area and rich pore structures, the as-prepared ZnFe2O4/rGO electrode with 44.3 wt.% rGO content exhibits a high specific capacitance of 628 F g−1 and long cycle life of 89% retention over 2500 cycles at 1 A g−1. This work provides a new process for synthesizing binary transition metal oxide and developing a new strategy for realizing high-performance composites for supercapacitor electrodes.
