Weak Solvent–Solvent Interaction Enables High Stability of Battery Electrolyte

“…In this way, the redox properties of the electrolyte components, including solvent, additive, and anion during the polarization, − as well as the recently proposed M + –solvent–anion complex formed during the desolvation process on the electrode surface, − have been widely studied to evaluate the electrolyte, since they can be highly influenced by the widely existing electrostatic interactions between M + , anions, and solvent molecules with uneven charge distribution. Then, varying the interactions of M + –solvent, M + –anion pair, and anion–solvent by changing the type and quantity of solvents, anions, additives, etc., have received significant attention recently to tune the electrolyte properties. − It is worth noting that solvent–solvent interaction has rarely been mentioned before, as such interaction is considered to be very weak, 1–2 orders of magnitude weaker than the ion–ion interaction between M + –anion and the ion-dipole interaction between M + –solvent .…”
