“…The building blocks of Tz, Th, and BT have been employed to produce many porous polymer anodes for LIBs owing to their high n‐type doping/dedoping abilities, such as the Tz‐containing polymers PAT‐COF, E‐SNW‐1/CNT, and f ‐CTF‐1, the Th‐containing polymers P33DT, PTTE, DBD‐CMP2, and TThPP, and the BT‐containing polymer PDCzBT . However, all of these polymers only contain one of the three building blocks.…”

Conjugated microporous polymers (CMPs) have been heralded as promising energy‐storage materials with advantages such as chemical flexibility, porous structure, and environmentally friendliness. Herein, a novel conjugated microporous polymer was synthesized by integrating triazine, thiophene, and benzothiadiazole into a polymer skeleton, and the Li+‐storage performance for the as‐synthesized polymer anode in Li‐ion batteries (LIBs) was investigated. Benefiting from the inherent large surface area, plentiful redox‐active units, and hierarchical porous structure, the polymer anode delivered a high Li+ storage capacity up to 1599 mAh g−1 at a current rate of 50 mA g−1 with an excellent rate behavior (363 mAh g−1 at 5 A g−1) and a long‐term cyclability of 326 mAh g−1 over 1500 cycles at 5 A g−1, implying that the newly developed polymer anode offers a great prospect for next‐generation LIBs.

“…Given that the conventional redox‐driven intercalation method will bring an unavoidable damage, Fan and co‐workers reported a new approach to prepare single‐layered and few‐layered CTF‐1 based on acid‐base‐driven intercalation reaction and subsequent oxidation exfoliation. [ 81 ] The electron‐donating property of networks is favorable to the acid intercalation. Therefore, the layered CTF‐1 allows a reversible intercalation of either oxidizing or nonoxidizing acid.…”

energy-storage systems with high specific energy, long lifespan, and excellent safety. [5][6][7] Among them, the rechargeable secondary batteries have been demonstrated as the most promising candidate for electricity storage and utilization. [8][9][10][11] As one of the most popular batteries, lithium-ion batteries (LIBs) have found immense success in consumer electronics and electric vehicles, and are under the consideration for energy-storage power stations. [12][13][14] However, the commercial LIBs based on transition metal-based inorganic compounds have encountered a bottleneck. [15][16][17] The charge storage of inorganic electrode materials is governed by the oxidation-state variation of transition metal centers and achieved a charge balance with the insertion of counterions. [18] Restricted by crystal lattice and structure stability, the size and valence of counterions are required to match the crystal structures, which severely limit further improvement of energy density. [19][20][21] Clearly, these factors intrinsically weaken the versatility of inorganic materials. For instance, the similar electrode materials, which are successful in LIBs, are not suitable for other alkali ions batteries. [22][23][24] Additionally, from the viewpoint of economical and renewable factors of mineral resources, the existing LIBs based on transition metals (e.g., cobalt, nickel, and manganese) are difficult to meet the requirement of large-scale energy storage. [25] Nowadays, various demands have been raised up for the state-ofthe-art batteries, not only in the enhancement of cycle life, fast charging, and safety, but also in the focus of cost, lightweight, pollution-free, and environmental benign. [26,27] Under this background, researchers gradually shift their studies on novel batteries system and electrode materials. [28][29][30][31] Among them, explorations on the possibility of using organic compounds as potential alternatives of current inorganic electrode materials have never been stopped. [32,33,66] Organics have been demonstrated as promising electrode candidates due to their variety, sustainability, relatively low cost, and environmental friendliness. [34][35][36] The structural diversity implies that the richness of organic materials will provide abundant options and room in this field. The molecule engineering means that the electrochemical properties of organic electrodes can be rationally tuned with different functional groups, which exhibits a good designability of organic materials. These important features allow various designable synthetic routes and convenient functionalization. Although organic electrode materials are endowed with many advantages, their development and Covalent-organic frameworks (COFs), featuring structural diversity, framework tunability and functional versatility, have emerged as promising organic electrode materials for rechargeable batteries and garnered tremendous attention in recent years. The adjustable pore configuration, coupled with the functionalization of frameworks through ...

As the world moves toward electromobility, our daily lives are flooded with variety of lithium ion batteries (LIBs), and the concerns of cost, safety and environmental friendliness of LIBs spring up in the minds of scientists. Although organic electrodes have been considered as promising alternatives to their inorganic counterparts, some intrinsic weaknesses still plague scientists, such as high solubility, low conductivity and sluggish ion diffusion. The emergence of covalent organic frameworks (COFs) attracts our attention because of their robust networks and open pores that could facilitate the infiltration of electrolyte ions when used as electrodes for metal-ion batteries (MIBs). In this review, we summarized the recent progress of COFs as electrode materials, and the strategies toward enhancing electrochemical performance of COFbased electrode in MIBs are discussed. Hopefully, this review will provide a fundamental guidance for future development of COF-based electrodes.
