Redox-active organic compounds have become promising electrode materials for the development of more sustainable, economical, and safer batteries. However, their high electrochemical performance is inherently associated with the use of low mass-loading electrodes with high carbon content, which collectively hinders their applicability in real batteries. This work presents an innovative approach for developing high-performance and practical organic electrodes through the synthesis of anthraquinone-based conjugated microporous polymers in the presence of carbon nanostructures and further processing into self-supported buckypaper electrodes. This effective method enables high-mass-loading hybrid electrodes (up to 60 mg cm^–2) with low carbon content (20 wt %), which attained high gravimetric capacity (83.7 mAh g_electrode^–1), high areal capacity (6.3 mAh cm^–2), good rate capability (0.8 mAh cm^–2 at 10C), and remarkable cycle stability (>80% capacity retention over 1000 cycles). These are the highest values reported for an organic electrode, constituting a great leap forward in the development of practical organic batteries.

氧化还原活性共轭微孔聚合物的电极工程，用于超高容量有机电池

氧化还原活性有机化合物已成为有前途的电极材料，可用于开发更可持续，更经济和更安全的电池。然而，它们的高电化学性能固有地与使用具有高碳含量的低质量负载电极有关，这共同阻碍了它们在实际电池中的适用性。这项工作提出了一种创新的方法，可通过在碳纳米结构存在下合成蒽醌基共轭微孔聚合物并进一步加工成自支撑的巴克纸电极来开发高性能实用的有机电极。这种有效的方法可以实现低碳含量（20 wt％）的高质量负载混合电极（最大60 mg cm ^–2），并具有高的称重能力（83.7 mAh g）。_电极^–1），较高的面积容量（6.3 mAh cm ^–2），良好的倍率容量（10 C时为0.8 mAh cm ^–2）和出色的循环稳定性（在1000次循环中，容量保持率> 80％）。这些是报道的有机电极的最高值，构成了实用有机电池开发中的巨大飞跃。
