Solid Electrolyte Interphase Film on Lithium Metal Anode in Mixed-Salt System

The effect of electrolyte salt on the solid electrolyte interphase (SEI) is discussed with respect to improvement of the lithium metal anode. Lithium bis(fluorosulfonyl)imide (LiFSI) and lithium nitrate (LiNO3) were dissolved together in dimethyl sulfoxide (DMSO), in which the ratios of LiNO3:LiFSI (x:100-x mol%) were in the range of 0
