Lithium iodide has been widely studied as a soluble redox mediator for lithium oxygen batteries in order to help promote more effective charging. Despite this research effort, ambiguities exist regarding the effectiveness of lithium iodide as a redox mediator. In a recent work, we have helped explain how lithium iodide influences the product formed during discharge; shifting from Li₂O₂, to LiOH, to LiOH-H₂O and LiOOH-H₂O depending on the amount and chemical environment of water present in the electrolyte. In this work, we provided a detailed framework for understanding how these various discharge products can be oxidized during charge based on solvent properties as well as the amount of water present. The importance of differing interactions between iodide, triioidide and iodine with glyme-based electrolytes with added water is discussed and a number of important behavior transitions at differing water concentrations are uncovered.
