“…As the conductivity vs temperature data obeys Arrhenius relationship, the nature of cation transference is quite similar to that occurring in ionic crystals, where ions jump into neighboring vacant sites and, hence, increase the ionic conductivity [25]. Similar behavior has been observed in a number of other polymer electrolytes [26,27]. The conductivity follows the relation,     0 exp(-E a /kT) where σ 0 is the proportionality constant, E a , the activation energy, T, the absolute temperature, and k is the Boltzmann constant.…”

“…The observed conductivity response in this temperature range therefore appears to be governed by these two factors. Such a variation in conductivity have also been observed around the melting temperature of the crystalline phase in PEO based composite electrolytes [3,29,[39][40][41].…”

Abstract. The present paper deals with ion transport studies on a new proton conducting composite polymer electrolyte -(PVAx:NH4SCN)y:PVAc system. Complexation and morphology of the composite electrolyte films are discussed on the basis of X-ray diffraction and differential scanning calorimetry data. Coulometry and transient ionic current measurements revealed charge transport through protons. The maximum ion conductivity was found to be 7.4.10 -4 S.cm -1 for the composition: x = 0.15, y = 0.12. The observed conductivity behaviour is correlated to the morphology of the films. The temperature dependence of the electrical conductivity exhibits Arrhenius characteristics in two different temperature ranges separated by a plateau region related to morphological changes occurring in the electrolyte.

“…36 These crystalline peaks are riding over a broad halo which is the indication of the amorphous phase present in the polymer PEO. It may also be observed that the "halo" is less prominent in pure PEO than PEO+LiPF 6 or PEO+LiPF 6 +BMIMPF 6 membranes.…”

Preparation and characterization of polymer electrolyte films of PEO+10wt.% LiPF 6 +xwt.% BMIMPF 6 (1-butyl-3-methylimidazolium hexafluorophosphate) containing dopant salt lithium hexafluorophosphate (LiPF 6 ) and ionic liquid (BMIMPF 6 ) having common anion PF -6 are reported. The ionic conductivity of the polymer electrolyte films has been found to increase with increasing concentration of BMIMPF 6 in PEO+10 wt.% LiPF 6 due to the plasticization effect of ionic liquid. DSC and XRD results show that the crystallinity of polymer electrolyte decreases with BMIMPF 6 concentration which, in turn, is responsible for the increase in ionic conductivity. FTIR spectroscopic study shows the complexation of salt and/or ionic liquid cations with the polymer backbone.
