Direct Evidence of Reversible Changes in Electrolyte and its Interplay with LiO₂ Intermediate in Li‐O₂ Batteries (Small 31/2024)

Li-O2 Batteries Experiments and calculations provide essential insights into the discharge/charge mechanisms of a Li–O2 cell using a carbon electrode and high-Gutmann donor number solvent. It revealed a dynamic reversible change in the DMSO molecule resulting from interaction of LiO2–(solvent)n, thereby confirming the solution mechanism for oxygen reduction reactions through an unprecedented analysis of the electrolyte molecule using operando Raman, supported by theoretical simulations.
