Lithium metal is the most attractive anode material for batteries because of its high specific capacity and low negative potential. However, lithium dendrite growth during lithium deposition leads to serious safety problems and poor cycling performance.

According to the previous reports, the electrochemical performance of lithium metal anode material for LIBs highly depends on the composition and physicochemical properties of the electrolytes used. However, a key factor with regard to electrolytes that can determine the electrochemical characteristics of the anode materials is not fully understood yet.

Thus, in the present work, we observed the electrochemical performance of lithium metal anode material as a function of electrolyte parameters, and elucidated the chemical/electrochemical reaction behavior of various electrolytes on the surface of lithium metal.
