“…It is well known that quinone-based compounds can be used as cathode materials for LIBs and SIBs, which are attributed to high reversibility with a suitable potential window. [102][103][104][105] Unfortunately, the batteries employing quinone-based compounds as cathode materials suffered from poor cycling performance, mainly due to their high solubility in electrolytes. To address the dissolution problem, the most effective strategy is to synthesize the insoluble polymers.…”

Newly developed charge storage and charge transport materials, such as organic polymers, demonstrate promise for applications in secondary batteries. Currently, such organic materials are regarded as promising candidates as substitutes for traditional metal materials for energy storage equipment because of advantages such as structural diversity, abundance, and environmental friendliness. The structural characteristics, electrochemical reaction mechanism, and properties of polymer electrode materials are comprehensively introduced. In addition, recent progress on implementing polymer‐based materials in lithium‐ and sodium‐ion batteries, as well as problems associated with the development of polymer electrodes, are discussed.

“…We find that the keto groups of AQ play a critical role in confining polysulfides by forming strong Lewis acid-based chemical bonding. Moreover, AQ can be easily linked to graphitic carbon through π–π stacking 32 . A small portion of reduced graphene oxide (rGO) not only improves the conductivity but also further suppresses the polysulfides dissolution by forming intimate contact between AQ and rGO to promote long-cycling Li–S battery.…”

Lithium–sulfur battery possesses high energy density but suffers from severe capacity fading due to the dissolution of lithium polysulfides. Novel design and mechanisms to encapsulate lithium polysulfides are greatly desired by high-performance lithium–sulfur batteries towards practical applications. Herein, we report a strategy of utilizing anthraquinone, a natural abundant organic molecule, to suppress dissolution and diffusion of polysulfides species through redox reactions during cycling. The keto groups of anthraquinone play a critical role in forming strong Lewis acid-based chemical bonding. This mechanism leads to a long cycling stability of sulfur-based electrodes. With a high sulfur content of ~73%, a low capacity decay of 0.019% per cycle for 300 cycles and retention of 81.7% over 500 cycles at 0.5 C rate can be achieved. This finding and understanding paves an alternative avenue for the future design of sulfur–based cathodes toward the practical application of lithium–sulfur batteries.

“…Furthermore, it suffers from dissolution in aprotic electrolyte and thus shows very short cycle life. To overcome these challenges, some efforts focused on filling active materials into the pores of mesoporous carbon or carbon nanotubes (CNTs), which provide a nanoconfinement effect and conductive host, whereas others worked on designing favorable molecular structures to attain better morphology and properties . The former restrains active materials into the nanochannels of carbon frameworks, but the open porous structure has limited capability of suppressing the dissolution of organic compounds, which generally requires additional optimization of separators or electrolytes.…”

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.
