Abstract Aqueous ammonium‐ion batteries (AAIBs) are promising candidates for next‐generation energy storage devices. However, organic materials as suitable anodes face severe challenges due to their structural instability and poor conductivity, which hinder the development of AAIBs. Herein, an innovative approach is introduced by incorporating benzoquinone framework, 5,7,11,14‐tetraaza‐6,13‐pentacenequinone (TAPQ), with reduced graphene oxide (rGO) using a solvent exchange method. Benefiting from π – interaction electron delocalization, TAPQ/rGO features enhanced cycling stability ion/electron transportation. Consequently, composite electrode delivers reversible capacity 181.7 mAh g −1 at 0.5 A achieves ultrahigh retention 94.5% over 10 000 cycles 5 , surpassing most reported in Combining density functional theory (DFT) calculation ex situ electrochemical characterizations, unique mechanism chelation coordination between NH 4 + N, O revealed. Furthermore, high‐performance ‐based full cell, assembled anode copper hexacyanoferrate (Cu‐HCF) cathode, demonstrates long‐term 93.95% after 500 cycles. This work pioneers concept interactions significantly improve performance, presenting novel strategy advancement AAIBs research.

Phthalocyanine (Pc), a macrocyclic aromatic compound, has attracted extensive attention in energy storage due to its large π-conjugated structure and abundant nitrogen sites. However, the poor solubility of Pc monomers leads rigorous polymerization conditions, which hinder application development Pc-based polymers. Herein, 1,4,5,8,9,11-hexaazatriphenylenehexacarbonitrile (HAT(CN)6) is used as precursor construct conjugated polymers (Pc-COPs) via molten salt assisted strategy. The physical–chemical properties resulting Pc-COPs at different synthesis temperatures were systematically studied, indicates that Pc-COP-350 (at temperature 350 °C) exhibits complete while maintaining redox activity active centers. As cathode material for aqueous zinc-ion batteries, exhibited best electrochemical performance, achieving specific capacity 269 mA h g–1 0.05 A g–1. Coulombic efficiency up nearly 100% even after long cycles current density 1 This work provides pathway designing synthesizing compounds.
