Lithium-sulfur battery suffers from the low utilization of sulfur and the high electrolyte/sulfur (E/S) ratio that decrease the cell-based performance. Lithium polysulfides (Li 2 S x)-dissolved electrolyte, so called catholyte, enables high utilization of sulfur, but the cell inherently has high E/S ratio due to the limited solubility of Li 2 S x.
As previously mentioned, Li-ion batteries contain four major components: an anode, a cathode, an electrolyte, and a separator. The selection of appropriate …
