“…Moreover, presence of silica may create more free volume in the composite which facilitates easy segmental motion of PEO chain at higher temperature and thus, increasing trend of conductivity with temperature. This is because rise in temperature provide more free volume in NCPEs that helps in easy flow of ions within NCPEs that finally leads to higher ionic conductivity ,. Thus, the Arrhenius behavior of conductivity below T m may be attributed to the hindered mobility of amorphous PEO segments confined within the crystalline regions, whereas VTF behavior above T m suggest the melting of crystalline phase of PEO resulting in higher segmental mobility.…”

Hybrid nanostructure polyethylene oxide (PEO)‐silica hybrids (PSH) prepared by sol‐gel chemistry are utilized as novel nanofiller to fabricate PEO‐based nanocomposite polymer elecytrolytes (NCPEs) by adopting the conventional solvent casting approach. The resulting PSH hybrids are characterized by various techniques followed by their incorporation into NCPEs that result in enhancement in the Li‐ion conductivity and a maximum ionic conductivity of 7.20 × 10−5 S cm−1 is achieved with only 0.25% nanofillers. The temperature dependence conductivity study shows a linear behavior below melting temperature following the Arrhenius equation and shows non‐linear behavior above the melting temperature following the Vogel–Taumann–Fulcher (VTF) equation. Argand plots of various NCPEs both at room temperature and elevated temperature signify the role of various relaxation processes for such type of conducting behavior, which is further supported by dielectric and tangential loss studies. Moreover, X‐ray diffraction and Differential Scanning Calorimetry measurements are carried out to understand the change in polymer crystallinity in the resulting NCPEs and are well in accordance with the conductivity changes.

“…( ) is generally believed to reflect the mechanism of charge transport among charge carriers. The Jonscher universality is not limited to analyze the AC conductivity in glass but has been extended to study the ac conductivity of polymer electrolytes [16]. In order to understand the conduction mechanism, different models have been proposed to explain the barrier hopping (CBH) and overlapping large polaron tunneling (OLPT) [18][19].…”

In searching for solutions to reduce battery weight for military applications, films of hexanoyl chitosan/polystyrene containing ) and titanium oxide were prepared using filler were used, which are untreated TiO 2 and on the structural and electrical behavior of the prepared electrolyte systems has been investigated by using X-ray and impedance spectroscopy, respectively. The ac conductivity was calculated rmula in the temperature range from 283 K to 353 K. The SO 3 -TiO 2 and can be interpreted based on the correlated hexanoyl chitosan; polystyrene; composite polymer electrolytes.

“…Looking at conductivity plots and dielectric constant plots one can tell that the ion motion and polymer chain segmental motions were coupled. 23 Enhancement in the dielectric loss with increase in ZnBr 2 wt.% can be correlated to conductivity. PVA exhibits intense dielectric -transition due to the presence of rotation of polar bonds of the side groups.…”

Different weight percentage of ZnBr 2 doped poly(vinyl alcohol) (PVA) free standing composite films were prepared using solution casting method. These films were characterized for analyzing structural, dielectric, electrochemical properties. This paper mainly focused to understand the contribution of physical phenomenon on conductivity in terms of dielectric parameters. FTIR spectrum confirms the interaction between ZnBr 2 and PVA. Pseudo-capacitive behavior observed from cyclic voltammograms. Dielectric properties of the composites follow non-Debye type behavior. The conducting phenomenon occurs due to hopping of ions between coordination sites present in the composite and the segmental relaxation of polymer chain.
