Electrophoretic NMR Reveals Migrating Solvation Structures in Li-ion Battery Electrolytes

David Halat – @davidhalat

We report 1H, 19F, and 7Li electrophoretic NMR (eNMR) measurements, which directly quantify ion and solvent motion under an electric field, to reveal solvent motion driven by cation–solvent coordination in Li-ion battery electrolytes. We further corroborate molecular dynamics solvation motifs by rationalizing concentration-dependent 1H NMR shifts through DFT calculations.
