Abstract
A novel amorphous FeSnOx nanosheet with hierarchical defects, including abundant oxygen vacancies and nano-sized perforations, that can be assembled into a multifunctional layer overlaying commercial separators for room-temperature sodium-sulfur batteries was developed on the Research Article (e202404816) by Junyu Hou, Binbin Jia, Guangmin Zhou, Jie Zhao et al. The oxygen vacancies offer strong adsorption and abundant catalytic sites for polysulfides, while the nano-sized perforations facilitate the regulation of Na-ion transport. The task-specific layer achieves ultra-light, ultra-thin, and ultra-robust properties, and boosts the electrochemical performance of sodium-sulfur batteries.
