High-capacity organic cathode boosted by coordination chemistry for energy-dense aqueous zinc-organic batteries.

ABSTRACT: N-type organic cathode materials containing carbonyl and imine groups have emerged as promising candidates for zinc-ion batteries due to their excellent charge storage capability, which arise from the synergic storage of both Zn²⁺ and H⁺. However, an increase in active sites also complicates the synthesis, introduces complex multi-electron reactions, and hinders comprehensive understanding of the charge storage mechanism and the evolution of molecular configuration during the electrochemical process. Herein, a 10-electron transfer organic cathode material, featuring imine and quinone groups that are spaced apart, was synthesized in one-step. Its highly conjugated molecular structure promotes electron delocalization, thereby enhancing the stability. The competitive sto
