Lithium–sulfur (Li–S) batteries are supposed to be one of the most potential next-generation batteries owing to their high theoretical capacity and low cost. Nevertheless, the shuttle effect of firm multi-step two-electron reaction between sulfur and lithium in liquid electrolyte makes the capacity much smaller than the theoretical value. …
Shuttle bus: A new mechanism based on the disproportionation reactions of polysulfides (PSs) to explain the rapid fading of capacity in Li/S batteries is reported. Two different electrolytes (i. e. a carbonate-based electrolyte and an ether-based electrolyte) are adopted to study the disproportionation mechanism.
