 This study proposes a novel separator material, UIOU-66GF, to improve the performance of aqueous zinc ion batteries. This material was found to be effective in enhancing the transport ability of charge carriers and orienting the zinc deposits in a preferred direction, resulting in improved battery performance. Specifically, the UIOU-66GF separator demonstrated high reversibility of zinc deposition and stripping, as well as long cycle life and excellent stability over time. These results suggest that UIOU-66GF can be used as a promising separator material for aqueous zinc ion batteries. This article was authored by Yong Song, Ping Chaowuan, Kai Wangmao, and others.
