Li-S batteries have a high theoretical specific energy calculated from Li metal anode and pure sulfur cathode. However, the reality is much lower number (Wh/kg) than Li-ion batteries, for which the reason is excessive amount of nonactive materials in Li-S cells, including almost every aspect of a battery: anode, cathode, electrolyte. There have been signficant effort to increase the practical energy of Li-S batteries, however, progress has been slow. Novel, disruptive strategies are needed to address fundamental issues and technical challenges. Here, we will discuss our recent understanding of Li-S cells under limited amount of electrolyte (so called "lean-electrolyte" condition), new cathode design and new electrolyte work.
