The solvation sheath of Li + -glyme was modulated to enhance Li + -TFSI - association by adopting a highly polar solvent, especially water molecules, which affects the solid electrolyte interface (SEI) layer composition. By the Li + -TFSI - association, a TFSI - anion-derived SEI layer is formed on the Li metal anode, resulting in higher Li metal anode efficiency.
