In this study, composite polymer electrolytes were prepared by addition of titanium oxide, TiO2nanofiller into polyvinylidene fluoride-co-hexafluoropropylene/polymethyl methacrylate-ammonium triflate (PVDF-HFP/PEMA-NH4CF3SO3) complex. The effect of TiO2on conductivity of the complex was examined using impedance spectroscopy. The highest room temperature conductivity of 1.32 × 10-3S cm-1was shown by the system containing 5 wt % of TiO2. This system was used for the fabrication of proton batteries with the configurations of (Zn + ZnSO4.7H2O + C + PTFE)/PVDF-HFP/PEMA-NH4CF3SO3-(5wt%)TiO2/(MnO2 + C + PTFE) and (Zn + ZnSO4.7H2O + C + PTFE)/PVDF-HFP/PEMA-NH4CF3SO3-(5wt%)TiO2/(MnO2 + PbO2+ C + PTFE). The performance of the batteries indicated potential application of the electrolyte system in proton batteries.

Cast Technique

Poly(vinyl) chloride (PVC)-NH4I-EC films have been prepared by solution cast technique. The sample containing 30 wt. % NH4I exhibited highest room temperature conductivity of 4.60 × 10-7S cm-1. The conductivity increased to 1.08 × 10-6Scm-1when 15 wt. % of ethylene carbonate (EC) was added to 70 wt. % PVC - 30 wt. % NH4I. Fourier Transform Infrared (FTIR) showed evidence of polymer–salt complexation while DSC showed increase in glass transition temperature (Tg) of PVC -NH4I - EC polymer electrolytes. The conductivity behavior of the studied system could be accounted by the changes in Tgvalues.

ABSTRACTWe have synthesized and characterized a range of novel polyelectrolytes containing weakly basic aluminosilicate anions in the polymer backbone in order to achieve t+ = 1 and high ionic mobility. Room-temperature conductivity is observed to increase in the series: [NaAl(OEOMe)2 ((OE)xO)2/2]n < [NaAl(OR)2(OSiMe2(CH2)3(OE)xO(CH2)3SiMe2O)2/2]n < [NaAl(OSiR3)(OSiMe2(CH2)3(OE)xO (CH2)3SiMe2O)3/2]n. This trend is ascribed to reduced ion pairing due to decreasing anion basicity, and lowered Tg resulting from increasing siloxy character. The addition of cryptand [2.2.2] increases conductivities by 1 -1.5 orders of magnitude. A maximum room-temperature conductivity is observed at a ratio of ≈10 etheric oxygens/cation. Related lithium polymer electrolytes were evaluated in mechanically joined solid state Li |PE |[LixMn2O4-C-PE] cells.

Ionic conductivity of poly(ethylene glycol) (PEG) - ammonium chloride (NH4Cl) based polymer electrolytes can be enhanced by incorporating ceramic filler TiO2into PEG-NH4Cl matrix. The electrolyte samples were prepared by solution casting technique. FTIR studies indicates that the complex formation between the polymer, salt and ceramic filler. The ionic conductivity was measured using impedance spectroscopy technique. It was observed that the conductivity of the electrolyte varies with TiO2concentration and temperature. The highest room temperature conductivity of the electrolyte of 7.72×10−6S cm-1was obtained at 15% by weight of TiO2and that without TiO2filler was found to be 9.58×10−7S cm−1. The conductivity has been improved by 8 times when the TiO2filler was introduced into the PEG–NH4Cl electrolyte system. The conductance spectra shows two distinct regions: a dc plateau and a dispersive region. The temperature dependence of the conductivity of the polymer electrolytes seems to obey the VTF relation. The conductivity values of the polymer electrolytes were reported and the results were discussed. The imaginary part of dielectric constant (εi) decreases with increase in frequency in the low frequency region whereas frequency independent behavior is observed in the high frequency region.

Hexanoyl chitosan that exhibited solubility in THF was prepared by acyl modification of chitosan. Films of hexanoyl chitosan-based polymer electrolyte were prepared by the technique of solution casting. The effect of plasticizers on the electrical properties of hexanoyl chitosan: LiCF3SO3 electrolytes have been investigated. The plasticizers used were EC, PC and a mixture of EC and PC. The highest room temperature conductivity of about 1.1 x 10-4 S cm-1 was achieved for electrolyte with composition of 50:50 (wt.%) mixture of PC: EC. The variations in conductivity have been explained using the Rice and Roth model from which the numbers of free ions per unit volume, mobility and diffusion coefficient of free ions were obtained. Electrochemical cells based on LiCoO2/MCMB couple were assembled using the electrolyte that exhibited the highest ionic conductivity. The performance of the cells have been studied and discussed in this paper.
