TL;DR: In this article, the authors show that singlet oxygen forms at the cathode of a lithium-oxygen cell during discharge and from the onset of charge, and accounts for the majority of parasitic reaction products.

TL;DR: In this paper, it was shown that disproportionation of superoxide, the product or intermediate on discharge and charge, to peroxide and oxygen is responsible for singlet oxygen (1O2) formation.

TL;DR: It is shown that organic redox mediators are predominantly decomposed by singlet oxygen that forms during cycling, indicating a strategy for the rational design of stable redoxmediators.

TL;DR: DABCOnium is an ionic liquid, non‐volatile, highly soluble in the electrolyte, stable against superoxide and peroxide, and compatible with lithium metal, which greatly reduces 1O2 related parasitic chemistry as demonstrated for the Li–O2 cell.
