Fig. 2: Regulating the coordination structure to weaken the interfacial interaction.

a Schematic of the function of Lewis-acid additives. b Raman spectra of PEO-LiTFSI and PEO-Mg-Al-LiTFSI electrolytes. c Snapshots obtained from MD simulations of the PEO-LiTFSI electrolyte and (d) the corresponding radial distribution functions. e Snapshots of the PEO-Mg-Al-LiTFSI electrolyte and (f) Radial distribution functions centered on the Li atom, (g) Mg atom, and (h) Al atom, white balls represent H atoms, as well as blue-N atoms, light purple-O atoms, yellow-S atoms, light blue-F atoms, pink-Al atoms, and orange-Mg atoms.
