文摘

Oxygen reduction mechanisms in Na+/pyrrolidinium ionic liquid mixtures reported. Onset of the oxygen reduction shifts more positive on increasing Na+ concentration. Remarkable cyclic coulombic efficiency (74%) observed in Na+/pyrrolidinium mixture. These observations provide a research platform for new Na–air battery electrolytes.
