“…Figure d shows the Nyquist plots of AAQ and AAQ@G, which consist of two parts. The semicircle in the high‐to‐middle frequency region corresponds to the charge‐transfer resistance ( R ct ) between the electrode and electrolyte whereas the sloping line at 45° at the low‐frequency region represents the Warburg impedance ( Z w ) associated with lithium‐ion diffusion in the electrode . The EIS results were simulated by using an equivalent circuit and the fitted parameters are shown in Figure S7.…”

Small conjugated carbonyl compounds are intriguing candidates for organic electrode materials because of their abundance, high theoretical capacity, and adjustable molecular structure. However, their dissolution in aprotic electrolytes and poor conductivity eclipse them in terms of practical capacity, cycle life, and rate capability. Herein, we report a foldable and binder-free nanocomposite electrode consisting of 2-aminoanthraquinone (AAQ) nanowires wrapped within the 3 D graphene framework, which is prepared through antisolvent crystallization followed by a facile chemical reduction and selfassembly process. The nanocomposite exhibited a very high capacity of 265 mA h g at 0.1 C for AAQ, realizing 100 % utilization of active material. Furthermore, the nanocomposite shows superior cycling stability (82 % capacity retention after 200 cycles at 0.2 C and 76 % capacity retention after 1000 cycles at 0.4 C) and excellent rate performance (153 mA h g at 5 C). Particularly, the nanocomposite can deliver the highest capacity of 165 mA h g among all reported anthraquinone- and anthraquinone-analogues-based electrodes per mass of the whole electrode, which is essential for practical application. Such outstanding electrochemical performance could be largely attributed to the wrapping structure of the flexible composite, which provides both conductivity and structural integrity.

“…Organic molecules could be used as cathode materials for SIBs as well. Chen et al prepared graphene/C 10 H 4 O 2 S 2 composite by the combination of a facile solution method and a simple dispersion–deposition process . With the help of unlimited electron transport via the 2D network of graphene, graphene/C 10 H 4 O 2 S 2 exhibited improved electrochemical properties in terms of higher reversible capacity and better cycling performance, as well as better rate capability in comparison with C 10 H 4 O 2 S 2 .…”

renewable energy is imperative and of great significance for human beings. As the ideal alternatives, green energy sources including wind, solar energy, water, and tide power have been widely applied in modern industry successfully, but their intermittent and variability feature cannot support all-weather utilization. [3][4][5] Hence, developing high-efficiency energy storage and conversion technology is a powerful measure to solve the above problems. Currently, there has been great interest in developing/refining high-performance electrochemical energy storage (EES) devices such as batteries, supercapacitors, and fuel cells. Among various EES technologies, secondary rechargeable batteries (e.g., lead-acid batteries, Ni-Cd batteries, nickel-metal hydride batteries, and lithium/sodium ion batteries) have been extensively studied and play an important role in modern electronics and transportation. [6] Typically, since the successful commercialization of lithium ion batteries (LIBs) by Sony in 1991, we have entered into an era of LIBs due to their high working voltage, long cycles, low self-discharge, large energy density, and low maintenance. [7] After rapid development over the past decades, the fabrication techniques and performance of LIBs have made great progress and matured significantly to be used as main power source for sophisticated electronics, [8] hybrid electric vehicles, and pure electric vehicles. [1,9] However, the high Scrupulous design and smart hybridization of bespoke electrode materials are of great importance for the advancement of sodium ion batteries (SIBs). Graphene-based nanocomposites are regarded as one of the most promising electrode materials for SIBs due to the outstanding physicochemical properties of graphene and positive synergetic effects between graphene and the introduced active phase. In this review, the recent progress in graphene-based electrode materials for SIBs with an emphasis on the electrode design principle, different preparation methods, and mechanism, characterization, synergistic effects, and their detailed electrochemical performance is summarized. General design rules for fabrication of advanced SIB materials are also proposed. Additionally, the merits and drawbacks of different fabrication methods for graphene-based materials are briefly discussed and summarized. Furthermore, multiscale forms of graphene are evaluated to optimize electrochemical performance of SIBs, ranging from 0D graphene quantum dots, 2D vertical graphene and reduced graphene oxide sheets, to 3D graphene aerogel and graphene foam networks. To conclude, the challenges and future perspectives on the development of graphene-based materials for SIBs are also presented.

“…1,2 It is most frequently encountered as an intermediate in the synthesis of ladder-type molecules [3][4][5][6][7][8][9][10][11] and high performance polymers [12][13][14][15][16][17][18][19][20] for organic solar cells (OSCs), while its electrochemical properties have been exploited in the development of organic batteries. [21][22][23][24] Efficient red thermally activated delayed fluorescence (TADF) is challenging due to the difficulty in simultaneously obtaining both a narrow singlet-triplet gap (E ST ) and a high fluorescence rate constant, and in overcoming the energy gap law which predicts that as the energy gap between the ground and excited states decreases, the rate of non-radiative decay (NRD) will increase. [25][26][27][28] Anthraquinone has been employed in some of the most efficient red TADF materials 29,30 however, electrochemical studies indicate that the thiophene containing analogue benzo[1,2-b:4,5-b']dithiophene-4,8-dione has a significantly deeper LUMO energy (ca.…”
