Raman Microspectrometry Applied to the Study of Electrode Materials for Lithium Batteries

摘要

Raman spectroscopy is a vibrational technique that provides unique structural information at the atomic scale1,2 on inorganic and organic compounds. By coupling an optical microscope to a conventional Raman spectrometer, the technique becomes a microprobe with a spatial resolution of less than 1 μm, determined by the wavelength of the radiation and the numerical aperture of the microscope objective. This has prompted several significant Raman applications in various fields dedicated to the characterization of a wide range of materials: inorganic solids, ceramics, semiconductor materials, protective coatings, polymers, and battery materials.
