Inhibited Passivation by Bioinspired Cell Membrane Zn Interface for Zn–Air Batteries with Extended Temperature Adaptability

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 27, 2024

Abstract Due to the slow dynamics of mass and charge transfer at Zn|electrolyte interface, stable operation Zn–air batteries (ZABs) is challenging, especially low temperature. Herein, inspired by cell membrane, a hydrophilic‐hydrophobic dual modulated interface constructed. This amphiphilic design enables quasi‐solid‐state (QSS) ZABs display long‐term cyclability 180 h@50 mA cm −2 25 °C. Moreover, record‐long time 173 h@4 −60 °C also achieved, which almost threefolds untreated QSS ZABs. Control experiments (in situ) characterization reveal that growth insulating ZnO passivation layers largely inhibited tuned hydrophilic–hydrophobic behavior. Thus, enhanced dynamic Zn 2+ from attained. As an extension, Al‐air (AABs) with bioinspired show unprecedented discharge stability 420 h@1 ‐40 °C, about two times AABs. bioinspired‐hydrophilic‐hydrophobic modulation strategy may provide reference for energy transform storage devices broad temperature adaptability.
