Abstract:Lithium-Sulfur (Li-S) batteries are considered as next generation energy storage for its low-cost, abundant and environmental-friendly cathode material and high theoretical energy density (2,600 Wh/kg), which is over five-fold of the state-of-art lithium-ion batteries. This promising battery technology still faces some challenges, and the most infamous one is the “shuttle effect” induced by high-order polysulfide intermediates, which leads to fast degradation of the battery. Significant efforts have been devot… 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.
