Composite polymer electrolytes based on poly (vinilydene fluoride-co-hexafluoro propylene) as polymer host, zinc triflate as dopant salt and ZrO2 as nanofiller were prepared by solution casting technique using N,N dimethylformamide (DMF) as solvent. The loading of the ZrO2 nanofiller carried out for the optimized composition shows an increasing trend of electrical conductivity from 10-11 to 10-5 Scm-1 at 298 K. The effective structural complexation of the polymer electrolyte system and influence of nanofiller were also analyzed by means of Fourier transform infrared spectral analysis. The detailed impacts on the degree of crystallinity were investigated by differential scanning calorimetric analysis. The electrochemical stability of the optimized composition with 7 wt% ZrO2 loading was found to exist up to 2.6 V.

Composite polymer electrolytes (CPEs) comprised of hexanoyl chitosan-polystyrene-LiCF3SO3-TiO2 were prepared by solution casting technique. The TiO2 fillers were treated with 4% sulphuric acid (H2SO4) aqueous solution. The effect of treated TiO2 on the structural and electrical behaviour of the prepared electrolyte systems was investigated by X-ray diffraction (XRD) and impedance spectroscopy, respectively. Addition of TiO2 decreases the crystallinity of the electrolytes. Ac conductivity was calculated from σ(ω) = εoεrωtanδ. It is found that at all frequencies, σ(ω) increases with increasing temperature. Dielectric constant decreases with increasing frequency and increases with increasing temperature.

(PEO+KNO3+Nano Al2O3) based Composite Polymer Electrolytes (CPE) has been prepared by using solution casting technique. In this technique, Poly (ethylene oxide) (PEO) and KNO3salt were dissolved separately in methanol and they were mixed together. Nano alumina (Al2O3) (particle size ~10nm) was doped to mixed solution and stirred for 24hrs. X-ray diffraction (XRD) technique has been obtained to determine complexation of salt and polymer in composite polymer electrolytes. Ionic and electronic transference numbers of these composite polymer electrolytes has been calculated by using Wagner’s polarization technique. The DC Conductivity of these composite polymer electrolytes has been evaluated in the temperature range of 303-373 K.

Composite Polymer Electrolytes

Composite polymer electrolytes (CPE) have recently received a great attention due to their potential application in solid state batteries. A novel polyindole based Fe2O3 dispersed CPE containing lithium perchlorate has been prepared by sol-gel method. The crystallinity, morphology and ionic conductivity of composite polymer electrolyte were examined by XRD, scanning electron microscopy, and impedance spectroscopy, respectively. The XRD data reveals that the intensity of the Fe2O3 has decreased when the concentration of the polymer is increased in the composite. This composite polymer electrolyte showed a linear relationship between the ionic conductivity and the reciprocal of the temperature, indicative of the system decoupled from the segmental motion of the polymer. Thus Polyindole-Iron oxide composite polymer electrolyte is a potential candidate for lithium ion electrolyte batteries. The complex impedance data for this has been analyzed in different formalisms such as permittivity (ε) and electric modulus (M). The value of ε' for CPE decreases with frequency, which is a normal dielectric behavior in polymer nanocomposite.

Different concentrations of TiO2 dispersed nano-composite proton conducting polymer electrolyte membranes were prepared using solution casting technique. Fourier Transform Infrared Spectroscopic analysis was carried out to determine the vibrational investigations about the prepared membranes. Variation of conductivity due to the incorporation of TiO2 in polymer blend electrolyte was analyzed using Electrochemical Impedance Spectroscopy and the value of maximum conductivity is 2.8×10-5 Scm-1 for 1mol% of TiO2 dispersed in polymer electrolytes. Wagner polarization technique has been used to determine the value of charge transport number of the composite polymer electrolytes. The electrochemical stability window of the nano-composite polymer electrolyte was analyzed using Linear Sweep Voltammetry. Fabrication of Proton battery is carried out with configuration of Zn+ZnSO4.7H2O+AC ǁ Polymer electrolyte ǁ MnO2+AC. Discharge characteristics were investigated for polymer blend electrolytes and 1mol% TiO2 dispersed nano-composite polymer electrolytes at constant current drain of 10μA. There is evidence of enhanced performance for proton battery which was constructed using 1mol% TiO2 dispersed nano-composite polymer electrolytes compared to the blend polymer electrolytes.

The solid membranes having different ratios of poly-vinyl alcohol (PVA), sodium perchlorate (NaClO4) and lithium perchlorate (LiClO4) were prepared using solution casting technique. The mixed-ion composite polymer electrolytes were characterized by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR) and conductivity measurement investigations. The XRD study confirms the amorphous nature of the mixed-ion composite polymer electrolytes. FTIR analysis has been used to characterize the structure of polymer which confirms the polymer and salt complex formation. The temperature dependent nature of ionic conductivity of the mixed-ion composite polymer electrolytes was determined by using conductivity meter (EC-035WP ERMA Inc, made in Japan). The ionic conductivity of the electrolyte was found in the range of 10-3 - 10-4 S/cm at room temperature.
