Abstract:1. Introduction
Elemental sulfur has extensive attentions because of its high theoretical specific capacity (1672 mA h g-1), natural abundance and low law-material cost. Therefore, sulfur is a promising candidate for a cathode of next generation batteries. However, there are many issues in fully demonstrating the potential of sulfur-based cathode for Li-S cells: intrinsically insulating of sulfur, large volume change during cycles and dissoluble lithium polysulfide intermediates (Li2Sn, 4 ≤ n ≤ … 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.
