Electronic Regulation Engineering of (NH₄)_0.25WO₃ Anode Enables Fast and Stable Rocking-Chair Zinc-Ion Batteries

Nano Letters, Год журнала: 2025, Номер unknown

Опубликована: Фев. 6, 2025

Rechargeable aqueous zinc-ion batteries (ZIBs) have emerged as promising candidates for energy storage due to their low cost, high safety, and theoretical density. However, the utilization of Zn anodes results in unsatisfied rate performance cycling stability dendrites, unsatisfactory stripping/plating efficiency, gas evolution. Herein, we propose a novel approach construct "rocking-chair" ZIBs with h-WO3 non-Zn anode address these issues. Metallic nonmetallic ion-doped (Cu-NWO) are designed deliver capacity an intercalation unique delocalized electronic structure active sites. Density functional theory calculations certify that Cu2+ preintercalation can strengthen electrochemical kinetics simultaneously reduce diffusion barriers on Zn2+ storage. The long cycle life density successfully realize self-powered electrochromic device, making them more suitable practical applications smart gird.
