摘要：

The addition of aluminum iodide (AlI3) to binary electrolytes,propylene carbonate mixed with dimethyl carbonate (PC/DMC) or ethylene carbonate mixed with DMC (EC/DMC), containing lithium bis(perfluoroethylsulfonylimide) (LiBETI) improved the charge;discharge cycle efficiency of a Li metal anode; the enhanced efficiency in EC/DMC with LiBETI was about 95 % even without the stacking pressure against the anode. In contrast, the AlI3 addition reduced the efficiency in a PC/DMC electrolyte containing lithium hexafluorophosphate (LiPF6). The AlI3 additive in the LiEETI electrolytes provided a low-resistance Li interface without predominant anion-decomposition as well as dendritic or mossy Li deposition.
