Abstract
AbstractOrganic electrodes that embrace multiple electron transfer and efficient redox reactions are desirable for green energy storage batteries. Here, a novel organic electrode material is synthesized, i.e., 2, 2′‐((disulfanediylbis (4, 1‐phenylene)) bis(azanediyl)) bis (naphthalene‐1, 4‐dione) (MNQ), through a simple click reaction between common carbonyl and organosulfur compounds and demonstrate its application potential as a high‐performance cathode material in rechargeable lithium batteries. MNQ exhibits the aggregation effect of redox‐active functional groups, the advantage of fast reaction kinetics from molecular structure evolution, and the decreased solubility in aprotic electrolytes resulting from intermolecular interactions. As expected, the MNQ electrode exhibits a high initial discharge capacity of 281.2 mA h g−1 at 0.5 C, equivalent to 97.9% of its theoretical capacity, and sustains stable long‐term cycling performance of over 1000 cycles at 1 C. This work adds a new member to the family of organic electrode materials, providing performance‐efficient organic molecules for the design of rechargeable battery systems, which will undoubtedly spark great interest in their applications.
