High lithium cycling efficiencies are required if a metal anode system is to be considered for use in Li-O-2 batteries. In this work electrolyte additives (0.3 M LiNO3 and 0.14 M VC) were used to increase the efficiency from 25 to 82.5% in the topical DMSO based electrolyte. Furthermore, we show that oxygen also acts to improve the cycling efficiency to 87%. This work highlights the importance of anode considerations in the development of metal O-2 batteries in alternative solvents (DMSO, Acetonitrile and DMA) and suggests realistic strategies for performance improvements.
