In situ Raman spectroscopy of single microparticle Li(super +) - intercalation electrodes

Article Abstract:

A novel experimental strategy that enables in situ Raman spectra of a single microparticle to be acquired while recording cyclic voltammograms at low scan rates, using LiMn2O4 in a Li(super +) - containing organic electrolyte as a model system is presented. Statistical analyis of the spectra obtained yielded results consistent with the information derived from XRD (X-ray diffraction) measurements making it possible to correlate optical data with phase composition for SOD (state of discharge) values in the range 11 and 35%.

Li-biphenyl-1,2-dimethoxyethane solution: Calculation and its application

Article Abstract:

Density functional calculations are carried out to investigate the molecular structure and thermodynamic parameters of intermediate complexes in the reaction and the reaction process in interpreted accordingly. The experimental vibrational bands are unambiguously assigned on the basis of the normal modes calculated for the biphenyl-Li-1,2-dimethoxyethane complex.

Surface-enhanced Raman scattering study on passivating films of Ag electrodes in lithium batteries

Article Abstract:

Li/Ag and Li/Al electrochemical cells composed of smooth Ag or Al electrode sheets, respectively, and matched with nonaqueous electrolytes are assembled and discharged. These discharged Ag electrodes are investigated using micro-Raman spectrometry.
