“…Ionic conductivity of the designed binder films was evaluated by electrochemical impedance spectroscopy (EIS) analysis. [ 28 ] Like high ionic conductivity of polysaccharides, [ 29 ] the chitosan specimen showed relatively high ionic conductivity (8.17 × 10 −6 S cm −1 ), and the chitosan–XNBR films showed higher ionic conductivity with higher chitosan contents (Figure S4, Supporting Information). Considering the results of various analyses, the Li–S cell with X1C3 binder was expected to show the most improved battery performance at high C rates (Figure 2d).…”

“…With a view to gain sufficient insight into the transport phenomena occurring within polymer-salt complexes in general and triflate ion-based systems in particular, there was an increased thrust during the last decade towards investigating new matrices for improving ion-conducting characteristics as well as in their detailed structural characterization by means of Fourier transform infrared (FT-IR) spectral features. The favorable scope of vibrational spectroscopic data is therefore expected to provide an exquisite tool for probing into the structural and functional features of macromolecular systems and aggregates [14][15][16][17][18][19][20][21][22].…”

Fourier transform infrared spectroscopic and electrochemical complex impedance studies have been carried out on a series of complexes containing poly (propylene glycol) of molecular weight 4,000 and silver triflate (AgCF 3 SO 3 ) salt corresponding to the ether oxygen to metal cation ratios (O : M) in the range 16:1 to 12:1. The formation of ion pairs and aggregates noticed in the case of specimens having high salt concentrations as well as the complete coordination of the cation with the ether oxygen at low salt concentrations within the PPG4000-AgCF 3 SO 3 polymer electrolyte system have been confirmed. The appearance of two weak triflate bands at 1,032 and 1,272 cm −1 in the absorption spectra in respect of low salt concentrations is indicative of the fact that triflate ions are free within the polymer matrix. The room temperature (298 K) electrical conductivity is found to increase with increasing ether oxygen content while exhibiting the maximum value of 7.1×10 −5 Scm −1 possibly due to silver ionic transport in the case of the typical composition having an O : M ratio of 16:1.

“…As the concentration of plasticizer increases, the amorphous nature of the electrolyte increases, thus improving the ionic conductivity of the polymer electrolyte. Plasticizers of poly(ethylene glycol) (PEG) with different molecular weight, PEG 200 , PEG 400 , and PEG 600, showed that the conductivity of a polymer electrolyte decreases as molecular weight of plasticizer increases [19]. PEG 200 has the largest concentration of free ions associated only with the anti-symmetric stretching mode in the matrix polymer.…”

Polyurethane acrylate (PUA) from vegetable oil has been synthesized and prepared for solid polymer electrolyte. Polyol has been end-capped with Toluene 2,4-Diisocyanate (TDI) followed by hydroxylethylmethylacrylate (HEMA) in a urethanation process to produce PUA. The mixtures were cured to make thin polymeric films under UV radiation to produce excellent cured films which exhibit good thermal stability and obtain high ionic conductivity value. 3 to 15 wt. % of ethylene carbonate (EC) mixed with 25 wt. % LiClO4 was added to PUA to obtain PUA electrolyte systems. PUA modified with plasticizer EC 9 wt. % achieved the highest conductivity of 7.86 × 10−4 S/cm, and relatively improved the linear sweep voltammetry, transference number and dielectric properties. Fourier Transform Infrared Spectroscopy (FTIR) and dielectric analysis were presented. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), followed by X-ray Diffraction (XRD) and morphology have been studied. The addition of plasticizer to the polyurethane acrylate shows significant improvement in terms of the conductivity and performance of the polymer electrolyte.
