Figure shows the number of oxygen atoms coordinating [Li] + as a function of composition and temperature. The number of G3 oxygens decreases from > 4 at low salt content to ∼ 1 at high salt content, while anion oxygens increase from ∼ 0 to > 3. Lithium-oxygen coordination depends primarily on composition, with minimal temperature dependence. Sitesite coordination numbers are discussed further below. For SILs composed of [Li][NTf 2 ] and G4, Dong et al. previously showed a similar behavior. In the equimolar mixture, [Li] + coordination involves four glyme oxygen atoms and one [NTf 2 ] -oxygen, with weak temperature dependence. Upon dilution, [Li] + becomes coordinated solely by G4.
