This work focuses on the electrical properties study of solid biopolymer electrolyte (SBE) based plasticized carboxy methylcellulose (CMC) doped dodecyltrimethyl ammonium bromide (DTAB). Different weight percentage of ethylene carbonate (EC) which acts as plasticizer was incorporated into SBE system and were successfully prepared via solution casting technique. The conduction properties of SBE was investigated by using electrical impedance spectroscopy (EIS). The incorporation of 10 wt.% EC was found to achieve the highest ionic conductivity with 1.00 10-3 S cm-1 at room temperature. All SBE samples shows the ionic conductivity increased proportionally with temperature thus obeys to Arrhenius behaviour with regression value almost close to unity (R2~1). The electrical conduction behaviour of the CMC-DTAB-EC SBE reveals non-Debye behaviour without single relaxation properties.

The present work deals with the findings on the ionic conduction behavior based on ethylene carbonate (EC) as plasticizer in carboxymethyl cellulose (CMC) – dodecyltrimethyl ammonium bromide (DTAB) for green polymer electrolytes (GPEs) that were prepared via solution casting technique. The highest ionic conductivity obtained for CMC-DTAB film was 7.72 x 10-4 S/cm and enhanced to 2.37 x 10-3 S/cm with addition 10wt. % of EC. The conductivity-temperature of GPEs system obeys the Arrhenius relation where the ionic conductivity increases with temperature. The temperature dependence of the power law exponent for plasticized CMC-DTAB based GPEs system follows the quantum mechanical tunneling (QMT) model for conduction mechanism.

<p class="TTPSectionHeading">Carboxymethyl cellulose–NH4NO3 solid biopolymer electrolyte films were prepared by solution casting technique. Ammonium nitrate (NH4NO3) with 5–50 wt.% were dissolved in disparate carboxymethyl cellulose (CMC) solution, respectively. The electrical properties and conduction mechanism of electrolyte films have been revealed by employing electrical impedance spectroscopy in the frequency range of 50 Hz to 1 MHz within the temperature range of 303 K to 353 K. The ionic conductivity was observed to be influenced by the NH4NO3 concentration. The conductivity–temperature relationship is Arrhenius. From dielectric loss variation with frequency, the power law exponent was obtained. The temperature dependence of the power law exponent for CMC– NH4NO3 system can be represented by the quantum mechanical tunneling (QMT) model.</p>

The gel polymer electrolytes (GPEs) composed of polymethylmethacrylate (PMMA) with lithium trifluoromethanesulfonate (LiCF3SO3) salt dissolved in a binary mixture of ethylene carbonate (EC) and propylene carbonate (PC) organic solvents have been prepared by the solution casting technique. The samples are prepared by varying the salt concentrations from 5 wt.% to 30 wt.%. Impedance spectroscopy measurement has been carried out to determine the ionic conductivity of the samples. The sample containing 25 wt.% of LiCF3SO3salt exhibits the highest room temperature ionic conductivity of 2.56 x 10-3S cm-1. The conductivity of the GPEs has been found to depend on the salt concentration added to the sample, while at higher salt concentration reveals a decrease in the ionic conductivity due to ions association. The temperature dependence of conductivity from 303 K to 373 K is found to obey the Arrhenius law. The ionic transference number,tiof GPEs has been estimated by the DC polarization method and the value is found to be 0.98, 0.93, and 0.97 for the sample containing 25 wt.%, 5 wt.% and 30 wt.% respectively. This result is consistent with the conductivity studies.

Gel polymer electrolytes synthesized from Poly(methylmethacrylate) (PMMA) as the host, ethylene carbonate (EC)/propylene carbonate (PC) as plasticizer and LiCF3SO3 (LiTf) as a salt has been prepared using solution casting technique. X-ray characterization confirms the complete dissociation of the LiTf salt in the gel polymer. The effect of LiTf  salt on ionic conductivity, ionic transference number (tion) and  mechanical characteristics were investigated. The ac impedance has been studied to evaluate the ionic conductivity. It was observed that the ionic conductivity of the prepared gel reached the highest value of  6.60 x 10-5 S/cm at 10.2 wt.% (1M) of LiTf salt. The temperature dependence studies showed that the samples were ionic conductors and seemed to obey the Vogel–Tamman–Fulcher (VTF) rule.  Dynamic mechanical  analysis (DMA) indicates that  the LiTf salt induces a remarkable increase in the storage modulus of the matrix at temperatures above the glass transition (rubbery plateau region).

This present work focuses on the conduction properties investigation on solid biopolymer electrolytes (SBEs) based alginate doped with various composition of glycolic acid (GA). The film was successfully prepared via solution casting technique and was characterized for conduction properties by using impedance spectroscopy. Based on ionic conductivity study, sample containing with 20 wt. % of GA possessed an optimum ionic conductivity of 5.32 × 10-5 Scm−1 at ambient temperature (303 K). The dielectric analysis revealed the highest ionic conductivity sample based alginate-GA SBEs has the highest dielectric constant and loss and increased significantly when temperature increases at ambient temperature. The dielectric properties shows that the entire alginate-GA SBEs are non-Debye behavior where there is no single relaxation occurred in the present system.

The room temperature ionic conductivity of the electrolyte composition 0.6PMMA-0.125(PC+DEC)-0.15LiClO4 (wt %) has been found to be maximum whose magnitude is 0.40×10-5 S/cm as determined by ac impedance analysis. The temperature dependent ionic conductivity of electrolyte sample0.6PMMA-0.125(PC+DEC)-0.15LiClO4 has further been investigated. Thermal analyses of electrolyte samples of all three compositions have also been done.

In the present work, using nanosized rare earth oxide CeO2 as filler and acetonitrile as organic solvent, a novel solid-state composite polymer electrolyte (CPE) films (PEO)10LiClO4-x wt.%CeO2 (x=0,2,6,9,12,15) was prepared by solution-casting technique. The effect of CeO2 filler concentration on morphology and electrical characteristics of CPE films has been investigated and analyzed. The AC impedance measurements show that the ionic conductivity of CPE can be efficiently enhanced by adding appropriate CeO2. The highest room temperature (25OC) ionic conductivity of 1.71×10-5S•cm-1 is achieved with the CeO2 content of 9 wt.%. With the CeO2 content continues to increase, CPE ionic conductivity begin to decline. This is because appropriate CeO2 can disorder the chain structure and effectively inhibit the crystallization of PEO, which expands the amorphous region required for the lithium-ion transport.

Sodium ion conducting gel polymer electrolyte (GPE) films consisting of polyvinylidenefluoride-co-hexafluoropropylene (PVdF-HFP) as a polymer host were prepared using the solution casting technique. Sodium trifluoromethane-sulfonate (NaCF3SO3) was used as an ionic salt and the mixture of ethylene carbonate (EC) and propylene carbonate (PC) as the solvent plasticizer. The GPE films were found to be stable up to temperature of 145 °C as shown by TGA analysis. The AC impedance study show that the optimum conductivity of 2.50 x 10-3 S cm-1 at room temperature is achieved for the film containing 20 wt.% of NaCF3SO3 salt. The temperature dependence of conductivity obeys VTF relation in the temperature range of 303 K to 373 K.
