摘要	Developing advanced electrolytes is indispensable for next-generation lithium-ion batteries (LIBs). Yet the strong solvating interaction between Li+ and various solvents often leads to sluggish desolvation and solvent co-intercalation into graphite electrodes, thus limiting the scope of electrolyte design. Here, we present a mechanism of dipole-dipole interactions to facilitate desolvation and inhibit co-intercalation through deliberately tuning the interactions among Li+, solvents and non-coordinating molecules (non-solvents). Specifically, the non-solvents counteract electrostatic attractions to tame the affinity between Li+ and solvents without altering the primary solvation structure at medium Li salt concentration. Consequently, the weakened Li+-solvent strength enables facile desolvation and thus superior electrochemical compatibility with graphite anodes for various solvents including DME (1,2-dimethoxyethane), DMSO (dimethyl sulfoxide), TMP (trimethyl phosphate), PC (propylene carbonate) and DEC (diethyl carbonate). We believe that the strategy of dipole-dipole interactions can extend the horizon of electrolyte design towards achieving advanced LIBs.
