Lithium/sulfur (Li/S) cells that provide an ultrahigh theoretical specific energy of 2600 Wh/kg are considered one of the most promising next-generation rechargeable battery systems for that electrification of transportation. Nevertheless , the commercialization of Li/S cells remains challenging, despite the recent advancements in materials development for sulfur electrodes and electrolytes, due in order to several critical issues such as the insufficient accessible specific energy and fairly poor cyclability. This evaluation aims to introduce electrode manufacturing and modeling methodologies and the current issues to be overcome. The particular obtainable specific energy values of Li/S pouch tissue are calculated with regard to various parameters (e. g., sulfur mass launching, sulfur content, sulfur usage, electrolyte-volume-to-sulfur-weight ratio, and electrode porosity) to demonstrate the style requirements for achieving a higher specific energy of & amp; gt; 300 Wh/kg. Finally, the prospects pertaining to rational modeling and production strategies are discussed, to establish a new design standard for Li/S batteries.
