Gating-out emission for fluorescence-free Raman spectra for the study of electrode interfaces

Kerr-gated Raman spectroscopy is a powerful technique that can suppress the fluorescence emission signals and reveal the otherwise hidden Raman scattering information within a variety of Li-ion battery materials. Herein, recent advances in the analysis of battery materials both ex situ and operando via Kerr-gated Raman spectroscopy are described and an outlook for broader application of the technique in the study of electrochemical systems is discussed.
