 This research paper examines the optimal electrolyte-slash-sulfur ratio for Lee-slash-S cells. The authors found that a specific capacity of 780 mAh G1 can be achieved when using a 72% sulfur cathode and 2mg Cm2 sulfur loading in an electrolyte consisting of 0.25 mLiso3Cf3-0.25mLeno3 dissolved in a 1,1WTWT mixture of DME and 1,3-dioxylene, DOL. This combination of components provides an optimized electrolyte-slash-sulfur ratio for Lee-slash-S cells, resulting in improved cycling performance. This article was authored by Xing S. Zhang.
