Abstract

Soluble redox species that facilitate the oxygen reduction reaction by mediating the LiO₂ intermediate and consequently the formation of the Li₂O₂ have attracted considerable interest for Li-O₂ batteries. Based on extensive radical studies, this work discloses a distinct solution reaction route when a quinone derivative was employed as a redox mediator.
