Overcoming magnetic susceptibility broadening in NMR of coin cell batteries to achieve chemical resolution

Fritzsching, Keith; Walder, Brennan; Gruenwald, Hannah K.; Mcbrayer, Josefine D.; Harrison, Katharine

We develop methods for previously introduced NMR hardware that enables sensitive, noninvasive spectroscopic study of coin cell batteries, by overcoming the magnetic field distortions intrinsic to the battery limited chemical resolution. Specifically, we employ an interferometric NMR technique to overcome field heterogeneity, reducing peak widths by two orders of magnitude and obtaining chemically resolved solution-state spectra.
