“…The increase in temperature implies enhancement of a number of mobile charge carriers contributing to the transport of ions and as a result, ionic conductivity increases [33]. This increase is due to the free volume model [34] and hoping of charge carriers between localized sites [35]. As the temperature is enhanced, local spaces are produced by the expansion of host material and, therefore, polymer segments can move into this free volume.…”

Sodium ion conducting gel polymer electrolytes based on polyacrylonitrile (PAN) with ethylene carbonate and dimethyl formamide as plasticizing solvents are prepared by the solution cast technique. These electrolyte films are free standing, transparent and dimensionally stable. Na ? ions are derived from NaI. The structural properties of pure and complex formations have been examined by X-ray diffraction, Fourier transform infrared spectroscopic studies and differential scanning calorimetric studies. The variation of the conductivity with salt concentration ranging from 10 to 40 wt% is studied. The sample containing 30 wt% of NaI exhibits the highest conductivity of 2.35 9 10 -4 S cm -1 at room temperature (303 K) and 1 9 10 -3 S cm -1 at 373 K. The conductivity-temperature dependence of polymer electrolyte films obeys Arrhenius behavior with activation energy in the range of 0.25-0.46 eV. The transport numbers both electronic (t e ) and ionic (t i ) are evaluated using Wagner's polarization technique. It is revealed that the conducting species are predominantly due to ions. The ionic transport number of highest conducting film is found to be 0.991. Solid-state battery with configuration Na/(PAN ? NaI)/(I 2 ? C ? electrolyte) is developed using the highest conducting gel polymer electrolyte system and the discharge characteristics of the cell are evaluated over the load of 100 KX.

“…7) indicates fast exponential type decrease in electrical conductivity initially, saturating later to almost constant values, which could be separated as electronic and ionic part by extrapolating the linear part to zero time for electronic and point-wise subtraction for ionic conduction. It is evident that mobile ions are present in the material [17].…”

The conductivity of poly(N-vinylimidazole) (PVIM) and its fluoroborate salt (PVIM-HBF 4 ) are reported here. N-vinylimidazole is polymerized by free radical method and PVIM-HBF 4 is prepared by acidification of PVIM with HBF 4 . The polyelectrolyte so formed has been characterized by infrared, hydrogen-1 nuclear magnetic resonance, thermogravimetric analyzer, and differential scanning calorimetry. Frequency and temperature dependence of AC conductivity has been studied to learn about the electrical conduction behavior in the materials. The electrical conductivity of the new material is found to be in the range of 10 −5 to 10 −6 S cm −1 .There is about 10 2 -to 10 3 -fold increase in conductivity of the polyelectrolyte. The material is shown to be a predominantly ionic conductor with t ion ≈0.88. Apparent activation energies are found to be 0.397 and 0.250 eV for the polymer and the polyelectrolyte, respectively.

“…The ionic conductivity of poly-(2-vinylpyridine)-HX, where X=Cl, Br, I, F, IO 3 , NO 3 , are found to be more than that of poly-2-vinylpyridine (P-2VP) [16][17][18][19][20]. Some other polyelectrolytes poly(2-dimethylaminoethylmethacrylate)-HCl, poly(4-vinylpyridine)-HX where X=Cl, Br, I are also reported [21][22][23]. Polyelectrolytes contain charged groups either cation or anion which are covalently attached to the polymer; therefore, only the counter ion is mobile [24].…”

The synthesis and conductivity study of 2-vinylpyridine-acrylonitrile copolymer and its hydroiodide/ hydrofluoride salts are reported here. The copolymer and the polyelectrolytes are characterized by infrared, proton nuclear magnatic resonance, thermogravimatric analysis, differential scanning calorimetry, X-ray diffraction, and gel permeation chromatography techniques. The alternating current conductivities are measured within the temperature range 30-90°C by varying the frequency from 42 Hz to 5 MHz and found to be significantly higher than that of the copolymer. There observed a 10 5 -and 10 4 -fold increase in ionic conductivities for the salts of HI and HF, respectively. The ionic transport numbers are measured with the help of standard Wagner polarization technique, and the values for HI and HF salts are 0.97 and 0.94, respectively, which are relatively higher than that of the copolymer (0.71). The apparent activation energies for conduction for the copolymer and its salts are also measured.
