Ionic interactions and transport characteristics of a new polymer electrolyte system containing poly(propylene glycol) 4000 complexed with AgCF3SO3

Abstract

The effect of concentration of AgCF 3 SO 3 salt on the behavior of ionic transport within the polymer electrolyte system containing the polymer host poly(propylene glycol) of molecular weight 4000 (PPG4000) has been investigated in terms of spectroscopic and electrochemical properties. It is evident that the presence of welldefined interactions between the ether oxygens and silver cations arising due to the complexation of the silver salt with the polymer matrix has enabled the chosen polymer electrolyte system to possess the maximum room temperature (298 K) electrical conductivity of 9.4 9 10 -5 S cm -1 in the case of the typical composition having the ether oxygen-to-metal ratio (O:M) of 4:1 and the lowest activation energy E a of 0.46 eV for Ag ? ionic conduction.

Dielectric and electric properties of plasticized PEO‐AgCF3SO3‐SiO2 nanocomposite polymer electrolyte system

“…In the high frequency side, the observed conductivity is not much temperature dependent as in low frequency, which suggests the electrochemical characteristics of the PEO‐AgCF 3 SO 3 ‐SiO 2 ‐PEG electrolyte system. Suthanthiraraj and Kumar [21] have attributed the observed behavior owing to the occurrence of ionic conduction arising due to Ag + ionic interaction and complexation phenomenon. The observed trends of the temperature dependence of AC conductivity can be seen in Fig.…”

Transference Number Determination in Poor-Dissociated Low Dielectric Constant Lithium and Protonic Electrolytes

“…Moreover, in some publications, the transport properties of the polymeric electrolytes are addressed without the meaningful determination of the basic and most prominent charge transport characterizing parameter—cationic transference number. Such an approach was presented for various groups of the materials studied including plasticized [ 31 ], hybrid [ 32 ], supramolecular compounds based [ 33 ] sodium conducting [ 34 , 35 , 36 ], or even silver ion-based [ 37 ] electrolytes. Therefore, it is important to stress that even if the suggested chemical structure of the electrolyte assumes this kind of features, one cannot neglect the counter effect of side reactions occurring in the synthetic step, as well as, the exploitation phase structure deterioration processes causing the existence of the mobile anionic charge carriers.…”

Ion dynamics and segmental relaxation of CeO 2 nanoparticles loaded soft - matter like gel polymer electrolyte

“…Moreover, the C-O-C stretching vibration is also changed with the environment of the salt and filler concentration. However, the band at 1110 cm −1 is more dominated in pure PPG 4000 and low salt concentration added electrolyte complex, whereas a new band arrived at 1106 cm −1 at higher salt concentration, which has been discussed in detail by us recently [17][18][19]. The same C-O-C band again shifted toward the lower wave number region ranging from 1110 to 1098 cm −1 associated with reduced intensity and the band become asymmetric too, with varying concentrations of CeO 2 filler particles is shown in Fig.…”
