Abstract
While showing promise as an alternative to lithium-ion (Li-ion) rechargeable batteries, lithium-sulfur (Li-S) batteries still face several hurdles before becoming competitive with current commercial batteries. In this work, we explore several avenues for improvement and overall understanding of the Li-S system. A thorough study of the effects of sulfur content on Li-S cell, including controlled sublimation of sulfur to moderate loading, showed several factors that contribute to sulfur performance. Preliminary study was conducted towards syntheses of hierarchical carbon support with the goal of mitigating polysulfide shuttling and maximizing the full energy storage potential of Li-S batteries by combining meso- and microporous structures within the carbon matrix.
