Carbon nanotubes decorated with zinc oxide quantum dots enables high-efficiency lithium-sulfur batteries

This work decorates carbon nanotubes (CNTs) with highly active zinc oxide (ZnO) quantum dots to form ZnO@CNT architectures. Such a "conductivity-polarity coupling" strategy efficiently rationalizes sulfur evolution procedures, leading to remarkable battery performance. We use minimal catalyst loading (quantum dot level) to control the battery performance outcomes, offering a promising pathway for advancing the practical deployment of lithium-sulfur batteries (LSBs).
