“…Electric modulus formalism is commonly analyzed to explore conductivity relaxation in electrolyte materials [9][10][11]25,29,30]. The advantages of this formalism are; firstly, it is free from EP effect due to unity product of ε*(ω) and M*(ω), and secondly, it is independent of the electrode material of the measuring cell.…”

“…3 The dielectric constant represents the stored charge in a material. Since charge is carried by ions, therefore it can be deduced that the increase in dielectric constant reflects the increase in the number of ions [14]. Fig.…”

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.

“…Electrode polarization means ion accumulation at electrode-electrolyte interface due to blocking electrodes. They block the mobile ions from moving into the external circuit which is responsible for the decrease in dielectric constant of the polymer electrolyte [65]. Imaginary part of dielectric constant of plasticized PVC-PBMA blend polymer electrolytes also decrease with increase in frequency which may be due to faster movement of ions which induce more friction.…”

Plasticized polymer electrolytes comprising of ethylene carbonate as the plasticizing agent in poly (vinyl chloride) [PVC]-poly (butyl methacrylate) [PBMA] blended polymer electrolytes were prepared by solution casting technique.Complex formation, structural elucidation, conductivity, dielectric parameters ( ′, ″, M′, and M″), thermal stability, and surface morphology are brought out from FTIR, XRD, ac impedance analysis, dielectric studies, thermogravimetry/ differential thermal analysis, and scanning electron microscopic studies, respectively. Polymer electrolytes are found to exhibit higher ionic conductivity at higher concentration of plasticizer at the cost of their mechanical stability. Conductivity of 1.879 × 10 −4 S cm −1 is exhibited by the polymer electrolyte consisting of 69% of plasticizer with appreciable thermal stability up to 523 K. Temperature and frequency dependence of conductivity is found to follow Vogel Tammann Fulcher relation and Jonscher power law, respectively. Real and imaginary parts of dielectric constants are found to decrease with increase in frequency which could be due to the electrode polarization effect.
