Infrared Photothermal Deflection Spectroscopy: A New Probe for the Investigation of Electrochemical Interfaces

Year: 1996

Type: article

Abstract: An infrared photothermal deflection spectroscopy system has been developed using infrared tunable diode lasers in the wavelength region from 8 to 16 μm. This system allows the collection of in situ optical absorption spectra of species at electrode/electrolyte interfaces in an electrochemical cell. The infrared spectra of LiOH and formed on the surface of a lithium foil were recorded. The infrared photothermal deflection spectroscopy technique has been used to monitor the lithium electrode surface in an operating cell, . The in situ spectra (in the region) show that the film formation at Li/polymer electrolyte interfaces is dominated by LiOH, although there also appears to be organic species in the surface film.
