Abstract

The growing need for higher power and energy density batteries requires a fundamental understanding of the solid electrode-liquid electrolyte interface (SLI). Details governing the salt solvation and desolvation mechanisms are critical for the interfacial charge transfer process across the solid-liquid interface. I will show in this talk that gap-mode SERS is ideal to probe salt solvation structure in the immediate vicinity (< 20 nm) of the solid-liquid interface. SERS lacks the nanoscale resolution in the sample plane. To compensate for this, TERS is used to probe the decomposition product or solid-electrolyte interphase (SEI) at 10 nm nanoscale resolution.
