Water Catchers within Sub‐Nano Channels Promote Step‐by‐Step Zinc‐Ion Dehydration Enable Highly Efficient Aqueous Zinc‐Metal Batteries

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(26)

Published: April 9, 2024

Abstract Zinc metal suffers from violent and long‐lasting water‐induced side reactions uncontrollable dendritic Zn growth, which seriously reduce the coulombic efficiency (CE) lifespan of aqueous zinc‐metal batteries (AZMBs). To suppress corresponding harmful effects highly active water, a stable zirconium‐based metal‐organic framework with water catchers decorated inside its sub‐nano channels is used to protect Zn‐metal. Water within narrow can constantly trap molecules solvated Zn‐ions facilitate step‐by‐step desolvation/dehydration, thereby promoting formation an aggregative electrolyte configuration, consequently eliminates corrosion reactions. More importantly, functionalized also act as ion rectifiers promote fast but even transport, leading dendrite‐free metal. As result, protected demonstrates unprecedented cycling stability more than 10 000 h ultra‐high average CE 99.92% during 4000 cycles. inspiringly, practical NH 4 V O //Zn pouch‐cell fabricated delivers capacity 98 mAh (under high cathode mass loading 25.7 mg cm −2 ) preserves 86.2% retention after 150 This new strategy in reversible anodes would spur utilization AZMBs.
