a Comparison of the HOMO and LUMO energy levels for various commonly used Li salts and ether-based solvents. b, c RDF plots of Li–OTHF, Li–OFSI−, Li–NFSI− and Li‒OTO pairs in THF- (b) and TO-based (c) electrolytes. d The calculated reduction potential of THF, TO and FSI− based on DFT. e, f Fitted Raman spectra in THF- (e) and TO-based (f) electrolytes at different temperatures. g, h 7Li-NMR (g) and 1H-NMR (h) spectra of THF- and TO-based electrolytes. Colors of elements: H, white; C, green; O, red. i Gel permeation chromatography (GPC) test results of TO-based electrolyte at 60 °C. j Schematic diagram of temperature-dependent solvation structure of TO-based electrolyte.
