“…The structures of C4Q/PPL, PPL, treated non‐crystalline C4Q, and crystalline C4Q were determined by powder X‐ray diffraction (XRD), and the results are shown in Figure . The treated C4Q showed a weak peak at 11.5° because of the presence of most C4Q molecules in amorphous state . For PPL, there are two diffraction peaks at 23° and 43° respectively, representing the (002) and (100) planes of the graphite structure with a low crystalline level.…”

“…To address both issues simultaneously,e mployingc onductive porous carbon materials to encapsulate C4Q shouldb ea good strategy. [7] Zheng [8] demonstrated that orderedm esoporous carbon CMK-3 could immobilize C4Qtoform acomposite, which has been used as the cathode material in LIBs with the initial discharge capacity of 427 mAh g À1 .A fter 100 cycles, the battery could still maintain 58.7 %o ft he originalc apacity because the encapsulatione ffectively alleviated the dissolution of C4Q in organic electrolytes. However,C MK-3 is relativelye xpensive, which might make the commercial application of this type of batteries impractical.Thus, searching cheap carbon materials to replaceCMK-3 is highly desirable.…”

Searching for new cheap encapsulating materials to decrease the solubility of organic small molecules as the cathode materials in electrolytes and improve the performance of organic lithium‐ion batteries (LIBs) is very important and highly desirable. In this research, we found that a novel cheap biomass carbon (named as PPL), prepared by pyrolyzing calyxes of Physalis Peruviana L, can efficiently encapsulate calix[4]quinone to form composites, which can be used as cathodes in LIBs. The initial discharge capacity of the as‐fabricated battery was 437 mAh g−1 and could maintain 228 mAh g−1 after 100 cycles. Even at 1 C, the discharge capacity was still 217 mAh g−1.

Organic batteries are considered as environmentally friendly alternative to lithium‐ion batteries due to the application of transition metal‐free redox‐active polymers. One well‐established polymer is poly(3‐vinyl‐N‐methylphenothiazine) (PVMPT) with a fast reversibility of the electrochemical redox reaction at a potential of 3.5 V versus Li|Li+. The oxidized PVMPT is soluble in many standard battery electrolytes, which diminishes its available specific capacity but at the same time can lead to a unique charge/discharge mechanism involving a redeposition process upon discharge. Herein, the influence of different conductive carbon additives and their properties, e.g., specific surface area, pore size distribution, and electrical conductivity, on the dissolution behavior of oxidized PVMPT is investigated. Compared to the state‐of‐the‐art conductive carbon Super C65 employed in many organic battery electrodes, Ketjenblack EC‐300J and EC‐600J reduce the dissolution of the oxidized PVMPT due to better immobilization on the carbon additive and in the resulting 3D structure of the electrode, as assessed by N2‐physisorption, electrochemical, UV–vis spectroscopy and scanning electron microscopy investigations. The studies demonstrate that a dense packing of the carbon particles in the electrode is decisive for the stable immobilization of PVMPT while maintaining its long‐term cycling performance.

With the rapid development of energy storage systems in power supplies and electrical vehicles, the search for sustainable cathode materials to enhance the energy density of lithium‐ion batteries (LIBs) has become the focus in both academic and industrial studies. Currently, the widely utilized inorganic cathode materials suffer from drawbacks such as limited capacity, high energy consumption in production, safety hazards, and high‐cost raw materials. Therefore, it is necessary to develop green and sustainable cathode materials with higher specific capacity, better safety properties, and more abundant natural resources. As alternatives, organic cathode materials possess the advantages of high theoretical capacity, environmental friendliness, flexible structure design, systemic safety, and natural abundance, making them a promising class of energy storage materials. Herein, the development history of the organic cathode materials and recent research developments are reviewed, introducing several categories of typical organic compounds as cathode materials for LIBs, including conductive polymers, organosulfur compounds, radical compounds, carbonyl compounds, and imine compounds. The electrochemical performance, electrode reaction mechanism, and pros and cons of different organic cathode materials are comparatively analyzed to identify the challenges to be addressed. Finally, the future research and improvement directions of the organic cathode materials are also proposed.
