“…Among the various materials being explored, COFs have been employed in the research for both supercapacitors and batteries. [319,[365][366][367][368][369] The structural customizability of COFs, achieved through the use of different linker combinations, enables the creation of diverse pore networks and size dis-tributions, functional groups, reactivity profiles, and stabilities in these EES devices. The field of COF materials has not yet witnessed an explosive growth, but over the past decade, there have been substantial advances and interest in synthetic methods and COF designs.…”

Covalent organic frameworks (COFs) are porous structures emerging as promising electrode materials due to their high structural diversity, controlled and wide pore network, and amenability to chemical modifications. COFs are solely composed of periodically arranged organic molecules, resulting in lightweight materials. Their inherent properties, such as extended surface area and diverse framework topologies, along with their high proclivity to chemical modification, have positioned COFs as sophisticated materials in the realm of electrochemical energy storage (EES). The modular structure of COFs facilitates the integration of key functions such as redox‐active moieties, fast charge diffusion channels, composite formation with conductive counterparts, and highly porous network for accommodating charged energy carriers, which can significantly enhance their electrochemical performance. However, ascribing intricate porosity and redox‐active functionalities to a single COF structure, while maintaining long‐term electrochemical stability, is challenging. Efforts to overcome these hurdles embrace strategies such as the implementation of reversible linkages for structural flexibility, stimuli‐responsive functionalities, and incorporating chemical groups to promote the formation of COF heterostructures. This review focuses on the recent progress of COFs in EES devices, such as batteries and supercapacitors, through a meticulous exploration of the latest strategies aimed at optimizing COFs as advanced electrodes in future EES technologies.

Due to their prominent power density, supercapacitors carve out a niche among all the energy storage systems. However, it is also well known that the energy density of supercapacitors takes no advantage over lithium‐ion batteries, the current star energy storage device. Therefore, substantial efforts have been paid to improving the energy density of supercapacitors not at the expense of its power density. To develop electrode with high capacitance is a direct and efficient way to increase the energy storage capability of supercapacitors. Organics whose molecular structure can be diversely designed to achieve high pseudocapacitance arising from redox active units in their backbone are good candidates as electrode materials for supercapacitors. Herein, this review summarizes recent progress of redox‐active organic electrode materials for supercapacitors and their pseudocapacitive energy storge mechanisms based on different organic functional groups. From the aspects of their preparation approaches, molecular design and the resultant electrochemical performances, the focus is to probe the relationship between the energy storage mechanisms and the molecular structure of redox‐active units and provide some insights for the further development of organic supercapacitor electrodes.
