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. These findings emphasize importance its potential advance development durable, rapid

Design of a polymer electrolyte membrane for enhanced zinc anode stability in reversible aqueous zinc-ion batteries

Energy Materials, Год журнала: 2025, Номер 5(9)

Опубликована: Май 16, 2025

Aqueous zinc-ion batteries (ZIBs) hold great promise for energy storage applications. Nevertheless, the realization of high-capacity ZIBs with extended cycle durability remains a significant scientific challenge, predominantly attributed to two inherent limitations: uncontrollable dendritic growth and concomitant side reactions. In this study, we present polymer electrolyte membrane denoted as TAC, which addresses these challenges by enhancing uniform distribution zinc ions. By incorporating phenolic hydroxyl groups from tannic acid (TA) onto surface cellulose fibers, TAC is synthesized, not only effectively shields both front back surfaces anode corrosive effects liquid electrolyte, but also exhibits high liquid-retention capacity under pressures up 5 MPa. Combining density functional theory simulations experimental investigations, demonstrate that TA actively engage ions, thereby significantly reducing desolvation during plating/stripping processes anode. The assembled battery utilizing 1% achieves remarkable performance, retaining 83.1% its discharge after 1,000 cycles at current C. Moreover, it reversibility, coulombic efficiency 99.9%, an impressive lifespan exceeding 2,300 h 0.5 mA cm-2. Furthermore, demonstrates excellent cycling stability across four different systems [ZnSO4, Zn(CF3SO3)2, Zn(OAc)2, ZnCl2], highlighting outstanding compatibility diverse compositions. exceptional performance underscores efficacy our design, offering novel strategy development fabrication membranes tailored aqueous ZIBs.
