The growing need for fast and reliable energy delivery in various applications ranging from electric vehicles portable electronics to grid-scale storage demands high-performance systems capable of operating at high charge/discharge rates (C-rates). Aqueous zinc-ion batteries (AZIBs) offer a promising alternative conventional lithium-ion primarily due their inherent safety, environmental friendliness, low cost, theoretical capacity. Quinone-based cathodes, with redox kinetics capacities, are particularly suitable high-rate applications. However, practical application AZIBs is limited by solubility aqueous electrolytes, leading significant capacity fading poor long-term cycling stability, especially elevated C-rates. To address these challenges, this study investigates the use Nafion membranes as ion-selective barriers stabilize quinone cathodes prevent dissolution active materials. evaluates four quinone-based cathodes─2,3,5,6-tetrachloro-1,4-benzoquinone (TCBQ), 1,4-naphthoquinone (NQ), anthraquinone (AQ), poly(2-chloro-3,5,6-trisulfide-1,4-benzoquinone) (PCTBQ)─in AZIBs, focusing on effect membrane conditioning 1 M ZnSO4 electrolyte. results demonstrate that optimized significantly enhances stability performance reducing dissolution, improving cyclability, maintaining stable retention under conditions, i.e., 35C.

High-Performance Bipolar Small-Molecule Organic Cathode for Wide-Temperature-Range Aqueous Zinc-Ion Batteries

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Апрель 3, 2025

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.

Abstract Recently, research on aqueous zinc‐ion batteries (AZIBs) has always focused improving the energy storage performance by increasing number of active sites, particularly in designing organic/polymer materials with a high density sites. However, does higher sites necessarily induce enhanced performance? To verify this issue, we have designed two linear polymers, where TAPT‐DHBQ contains an additional pair (carbonyl groups) compared to TABQ‐DHBQ, theoretical specific capacities 545.26 and 379.14 mAh g −1 , respectively. Interestingly, experimental results deviated these polymers being comparable, measuring be 325 (TABQ‐DHBQ) 280 (TAPT‐DHBQ). This is attributed competition effect between neighboring which leads decreased utilization As result, Zn//TABQ‐DHBQ ZnI 2 electrolyte additive exhibited 618 360 at current densities 1 10 A along 678.6 Wh kg (1 ). The finding underscores importance uniform electron cloud distribution cathode for achieving efficient AZIBs.
