The Lithium–Oxygen Battery with Ether‐Based Electrolytes

Electrolyte puts up a fight: The electrolyte is one of the greatest challenges facing the development of the non-aqueous Li–O2 battery. Although ether-based electrolytes do from Li2O2 on the first discharge, it is shown by various techniques that they also decompose and that decomposition increases while Li2O2 decreases on cycling (see picture). Thus, these electrolytes are not suitable. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
