TL;DR: Raman and infrared spectroscopic studies and conductivity and viscosity measurements of propylene carbonate (PC) doped with various concentrations of lithium perchlorate are reported in this paper.
Abstract: Raman and infrared spectroscopic studies and conductivity and viscosity measurements of propylene carbonate (PC) doped with various concentrations of lithium perchlorate are reported. The assignment of the vibrational modes was supplemented by AM1 normal coordinate analysis. Both Raman and infrared spectra showed band splitting in the fundamental vibrational frequencies of PC and perchlorate anion. Spectral curve fitting within the totally symmetric perchlorate band shape showed contributions of free ion, solvent-shared ion pairs, and contact ion pairs. Strong Li + -PC interaction was observed for the PC ring deformation band at 112 cm -1 . Ion pairing as deduced by spectroscopic techniques provided a rationale to account for conductivity and viscosity data

TL;DR: In this paper, the structural, optical and electrical properties of lithium galvanic thin film cells of 100 μA h capacity are investigated, showing that the lithium diffusivity increases with the temperature T s of preparation of the film and reaches a value of 10 -11 cm 2 s -1 in Li x MoO 3 and 10 -9 cm 2 S -1 for Li x V 6 O 13 for T s = 250°C.
