Abstract:
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.
