a Raman spectra of the solvents and electrolytes. b Simulated structures of 1.3 M LDC electrolyte. c Proportion of FSI−/DME with different ratios in 1.3 M LDC electrolyte. d Typical Li+ solvation structures with FSI−/DME ratio of 3/1 and 2/1. e Number of adjacent Li+ ions centered on the FSI− anions. f Radial distribution functions of Li-ODME, Li-OFSI-, and Li-ClDCE pairs in 1.3 M LDC electrolyte. XPS depth profiles of g F 1 s spectra, h Cl 2p spectra, i C 1 s spectra, and j Li 1 s spectra. The LMA is obtained from a Li | |Cu cell, which is cycled at 0.5 mA cm−2 with a fixed capacity of 4 mAh cm−2.
