Molecular Engineering and Microstructure Modulation of High‐Performance Organic Batteries

Organic electrode materials (OEMs) featuring high abundance, structural designability, and eco‐friendliness, are considered promising candidates for rechargeable metal‐ion batteries. Nevertheless, the realization of efficient metal‐ion batteries based on OEMs is plagued by the poor intrinsic electronic conductivity and low insolubility of OEMs in common organic electrolytes. Herein, we present a systematic discussion of advancements in the design of OEMs from the perspective of molecular engineering and microstructure modulation, aiming at tuning the electrochemical, physical, and chemical properties of OEMs. Additionally, we elucidate the reaction mechanism of regulation strategies and provide new design directions for OEMs. This review offers essential concepts and perspectives on the development of advanced OEMs for rechargeable batteries.
