 Abstract, lithium-sulfur batteries are promising candidates for next-generation energy storage devices due to their high energy density. However, the use of liquid electrolytes has been hindered by severe shuttle effects and intrinsic safety concerns. Solid-state electrolytes have been introduced to address these issues, but the lack of design principles for high-performance composite sulfur cathodes limits their further application. This paper reviews the challenges of regulating composite sulfur cathodes with respect to ionic-slash-electronic diffusions, and proposes solutions for achieving stable positive electrodes. Finally, the paper outlines future research directions to guide the development of high-performance all-solid-state lithium-sulfur batteries.
