Abstract:Rechargeable metal–sulfur
batteries with low-cost, soil-rich
elemental sulfur as the cathode have attracted considerable attention,
as they are crucial for working at room temperature due to their high
energy density, high output efficiency, and convenient operation.
However, the performance is limited by the low utilization of sulfur,
severe volume expansion, and shuttle effect of polysulfides. To address
these issues, a key strategy is to design carbon materials with excellent
conductivity and high specific … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
