Organic small-molecules with redox activity are promising cathode candidates for aqueous zinc-ion batteries (AZIBs) due to their low cost, high safety and theoretical capacity. However, severe dissolution leads unsatisfactory electrochemical performance. Here, a dihydro-octaaza-pentacene (DOP) compound is synthesized as AZIBs by extending its N heterocyclic molecular structure. The extended structure provides dual active sites of n-type (C═N) p-type (-NH-) reactions while reducing through enhanced π-conjugation. Hence, the Zn//DOP battery demonstrates improved performance, e.g., an capacity 360 mAh g-1 at 0.05 A g-1. Even under temperature conditions - 50 °C, still maintain capacities 172 312 g-1, respectively. In/ex-situ spectroscopy provide thorough understanding storage mechanisms cations anions (Zn2+/H+ ClO4-) multielectron transfer process occurring electroactive sites. This strategy offers approach designing high-performance zinc-organic sustainable energy storage.

Aqueous rechargeable manganese (Mn)-ion batteries have recently emerged as a promising candidate for multivalent ion batteries. However, challenges remain, particularly in expanding the electrolyte's voltage window and identifying compatible anode materials. Herein, we introduce Mn-ion full battery comprising nickel hexacyanoferrate (NiHCF) cathode, perylene-3,4,9,10-tetracarboxylic diimide (PTCDI) anode, novel hydrated eutectic electrolyte formulated from Mn(ClO4)2·6H2O acetamide. This composition, optimized molar ratio, provides stable solvation structure that suppresses water reactivity supports high ionic conductivity, confirmed by spectroscopic molecular dynamics analyses. The PTCDI facilitates highly reversible Mn2+ storage via unique enolization redox reaction, delivering exceptional rate capability cycling stability. As result, NiHCF||PTCDI achieves 1.2 V plateau, excellent performance (up to 5.0 A g-1), long life with 95.6% capacity retention over 1200 cycles at 1.0 g-1. study proposes feasible strategy construction of environment-friendly, long-life low-cost aqueous batteries, offering sustainable high-performance solution future energy applications.
