Abstract Lithium‐ion batteries (LIBs), known for their high energy density and long cycle life, have become indispensable in everyday applications. Unfortunately, the increasing demand LIBs raises concerns about sustainability of lithium resources. Non‐lithium metal‐ion therefore garnered significant attention due to abundant resources potential cost advantages. Yet, widespread adoption is hindered by limited availability high‐performance cathode materials. Organic electrode materials (OEMs) emerged as promising candidates, owing structural diversity tunability, allowing them accommodate large cations. Despite potential, most OEMs suffer from unsatisfactory cyclability, poor rate performance, low density. This review summarizes recent advancements improving electrochemical performance OEMs, focusing on molecular engineering approaches mitigate dissolution, enhance conductivity The charge storage mechanism current challenges associated with are first discussed. Various strategies designed address these then explored, including linkage improve stability electronic Finally, insights provided future development next‐generation battery technologies beyond LIBs.

Organic anode materials have been considered as promising electrodes for achieving low-cost and sustainable lithium-ion batteries (LIBs). However, organic face challenges, such inadequate cycling stability sluggish reaction kinetics, leading to an unsatisfactory LIB performance. Covalent frameworks (COFs) possess a porous designable structure coupled with exceptional stability, making them candidates in LIBs address the challenges. Herein, two piperazine-linked conjugated phthalocyanine-based COFs (named CoPc-BTM-COF CoPc-DAB-COF) were fabricated from reacting hexafluorophthalocyanine cobalt(II) (CoPcF16) 1,2,4,5-benzenetetramine (BTM) 3,3'-diaminobenzidine (DAB), respectively. Powder X-ray diffraction electron microscopy analyses combination theoretical simulation reveal their crystalline nature sql net AA arranged stacking pattern.

Abstract Covalent organic frameworks (COFs) have latterly emerged as a promising platform for devising electrode materials used to acquire high‐performance lithium‐ion batteries (LIBs). However, the preparation of COFs with fast redox kinetics, high‐efficiency utilization active sites, superior stability, and high conductivity remains challenge. Herein, thiophene‐based bipolar‐type (denoted TT‐TPDA‐COF) featuring extended conjugation, rich multiple redox‐active sites (C─S, C─N, C═N), hierarchical micro‐mesoporosity is synthesized. TT‐TPDA‐COF exhibits significantly increased density enhanced electrical compared its corresponding counterpart (Np‐TPDA‐COF). Remarkably, when LIBs cathode, it shows exceptional specific capacity up 309 mA h g −1 at 200 , surpassing that Np‐TPDA‐COF (195 ), energy 714 W kg superb rate property (182 5000 impressive preservation 84.3% after cycles .
