Published: Feb. 14, 2025

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.
