“…This conclusion can also be confirmed by the Nyquist plots of the electrodes, as shown in Figure 4E . Both the Nyquist plots of the two electrodes contain one semicircle in high frequency region corresponding to charge transform resistance at electrolyte/electrode interface and an upward line in low frequency region associated with ion diffusion in electrolyte ( Adhikari et al, 2020 ; Gurten and Aktas, 2020 ; Pang and Wang, 2021 ). The Ni-AC electrode has smaller charge transferring resistance than that of the AC, which contributes to the enhanced graphitization degree boosting conductivity.…”

“…Supercapacitors, as a kind of promising energy storage device with high power density and long service life, have excited great interest owing to their potential application in portable electronics and electric vehicles ( Qin et al, 2021 ; Reece et al, 2020 ; Yang L et al, 2021 ; Zhu et al, 2019 ). Based on different energy storage mechanisms, supercapacitors are mainly divided into two categories: faradic pseudocapacitors, in which transition metal oxides and conducting polymers are used as active materials, and electrical double-layer capacitors (EDLCs), in which carbon-based materials are often used as active materials ( Adhikari et al, 2020 ; Liu T et al, 2020 ; Say et al, 2020 ). The energy storage mechanism of EDLCs depends on the attraction of positive and negative charges at the interface of electrode and electrolyte, enabling high power density and ultralong cycling life of EDLCs ( Fleischmann et al, 2020 ; Pai et al, 2021 ; Pourhosseini et al, 2021 ).…”

Catalytic graphitization opens a route to prepare graphitic carbon under fairly mild conditions. Biomass has been identified as a potentially attractive precursor for graphitic carbon materials. In this work, corn starch was used as carbon source to prepare hollow graphitic carbon microspheres by pyrolysis after mixing impregnation with nitrate salts, and the surface of these carbon microspheres is covered with controllable pores structure. Under optimal synthesis conditions, the prepared carbon microspheres show a uniform pore size distribution and high degree of graphitization. When tested as electrode materials for supercapacitor with organic electrolyte, the electrode exhibited a superior specific capacitance of 144.8 F g−1 at a current density of 0.1 A g−1, as well as large power density and a capacitance retention rate of 93.5% after 1,000 cycles in galvanostatic charge/discharge test at 1.0 A g−1. The synthesis extends use of the renewable nature resources and sheds light on developing new routes to design graphitic carbon microspheres.

“…Subsequently, a porous PDI-polydopamine-rGO electrode specific capacitance of 610 F g −1 was generated via ultraviolet irradiation. [18] In this study, we successfully designed and synthesized a new type of quinone-like organic molecule (naphthalene diimide (NDI)), with a large symmetrical conjugate structure and two electron-withdrawing imide groups. The NDI molecule was used as a guest to modify rGO sheets to obtain the rGO-NDI composition by using non-covalent strategy.…”

prevent them from migrating in the electrolyte solutions between the negative and positive electrodes, which generate shuttle effect to lead to energy loss. [3] In addition, the carbon substrate can also help active organic molecules to release energy storage performances due to the high electrical conductivity and good electrochemical catalysis. In the Li-ion batteries, lots of organic molecules have been selected to prepare OMEs, such as organodisulfides, conducting polymers, conjugated carbonyl compounds, and nitroxyl radical polymers. [4,5] Especially, the carbonyl organic compounds as potential electrode candidates have been widely studied because of their large theoretical capacity, structural diversity, and inexpensive. For instance, calix[4]quinone (422 mAh g −1 vs Li/Li + ), [6] 1,4-benzoquinone (157 mAh g −1 vs Li/Li + ), [7] 1,4-bis(pbenzoquinonyl)benzene (306 mAh g −1 vs Li/Li + ), [8] and so on have been proven to exhibit excellent performance in specific capacity. Actually, the OMEs can not only store charges through redox reactions of groups on the molecular skeletons but also contribute electrical double layer capacitance to the whole electrode due to the surface electrochemical properties of conductive carbon substrates. Therefore, OMEs has become increasingly popular in the electrode applications for supercapacitors (SCs). In recent years, the organic molecules with benzoquinone structure, especially quinones (phenols) and their derivatives, have represented a tremendous potential to achieve super-capacitive performances in terms of larger capacitance, long-cycle life, and high-rate capability. [9] For example, Gogotsi et al. found that 2,5-dimethoxy-1,4-benzoquinone (DMQ) immobilized reduced graphene oxide (rGO) to form DMQ@rGO composite under the hydrothermal conditions. It is noted that the DMQ@rGO acquires excellent specific capacitance (600 F g −1 ) with outstanding capacitance retention (99%). [10] Wang et al. used the sodium anthraquinone-2-sulfonate (AQS) to functionalize the rGO sheets and prepared an AQS@rGO electrode with larger specific capacitance (567.1 F g −1 ) and long cycling-life (89.1% over 10 000 cycles). [11] Available commercialized quinones (phenols) molecules are less in categories and insufficiently variable in the A new redox-active organic molecule, naphthalene diimide derivative (NDI), is synthesized through the condensation reaction for electrochemical energy storage, in which 1,4,5,8-naphthalenetetracarboxylic dianhydride and 4-aminophenol are used as skeleton and substituent, respectively. The NDI is acted as a guest molecule to non-covalently modify reduced graphene oxide (rGO) and to form an organic molecular electrode (OMEs). The resultant electrode exhibits outstanding performance under the three-electrode configuration, including specific capacitance (354 F g −1 at 5 mV s −1 ) and cycling performance (87.2% after 8000 cycles). Furthermore, the electrochemical behaviors of the OMEs are mainly controlled by surface reactions and pseudocapacitance contribution is...

In our daily lives, electrochemical energy storage technology is of great importance due to our dependence on renewable energy sources (such as solar, wind, geothermal, tidal, and biofuel energy), portable electronics, and forecast of the tremendous markets for electrification of transportation in the near future. [1][2][3][4] The electricity (electric power) can be electrochemically stored in batteries, fuel cells, and electrochemical supercapacitors (SCs). [5,6] Among these electrical energy storage (EES) devices, SCs have attracted more attention due to their higher charge-discharge efficiency, outstanding power density, and significant cyclic stability. [7][8][9][10] In the operation of SCs, there are two types of charge storage mechanisms such as 1) electrical double-layer capacitors (EDLCs) and 2) pseudocapacitors, i.e., Faradaic redox reactions stored the charge. [11] Moreover, in recent years, hybrid capacitors are developed, which consists of an electrode for EDLCs and a battery electrode. [12,13] In last two decades, it was investigated that pseudocapacitors can yield 10-100 times higher specific capacitance than EDLCs. [14,15] For pseudocapacitors, the most commonly utilized electrode materials are transition-metal oxides [16][17][18] and conducting polymers such as polyaniline, polythiophene, and polypyrrole. [19][20][21] The pseudocapacitors based on conducting polymers are more cost-effective than transitionmetal oxides but displayed delayed behavior of Faradaic redox reactions leading to lower power density than EDLCs, swelling of electrodes, which, in turn, hamper the cycle-life stability of the SCs. [22,23] To overcome these drawbacks, in recent decade energy storage devices based on organic molecule electrodes (OMEs) have been developed. [24] Although the OMEs are very good, inexpensive, and green alternative electrode materials, their performance is not up to the mark when compared to inorganic counterparts. [25] Researchers overcome these limitations by fabricating electrode materials using organic molecules with desired properties and conducting carbon scaffolds. The carbon scaffolds are modified with the organic compounds via noncovalent interactions such as π-π stacking or covalent chemical bond formation. [26] Thus, the organic compounds are anchored on carbon materials, which, in turn, prevent their migration in
