Studies of dielectric relaxation and a.c. conductivity in [(100−x)PEO + xNH4SCN]: Al-Zn ferrite nano composite polymer electrolyte

Preparation and physical properties of (PVA)0.75(NH4Br)0.25(H2SO4)xM solid acid membrane

“…Generally for ionic conductors power law exponents (n) can be between 1.0 and 0.5, indicating the ideal long range pathway and diffusion limited hopping (tortuous pathway) respectively. The frequency response of the conductivity is interpreted in terms of jump relaxation model [19], where the conduction is due to translation and localized hopping. In jump relaxation, the charge carrier (ion) hops in atomic scales in both space and time.…”

The physical and chemical properties of gamma ray irradiated polymer electrolyte films

“…These polymeric materials is also contains characteristic advantages like easy film formability, good possibility, more flexible, cost effective, elasticity, plasticity and environmental stability etc. These prominent characteristic properties of polymer electrolyte were recognized as the most suitable for fabrication of various electrochemical devices such as solid state battery, solar cell, super capacitor, optical display devices, and sensors etc., [4][5][6]. There are various polymers were used to establish the polymer electrolytes such as polypropylene oxide (PPO), polyvinyl alcohol (PVA) and PEO, among these PEO is a semi crystalline polymer with a wide range of applications [7] because of its material characteristics like easily soluble in various inorganic solvents, low glass transition (~− 85°C) and most active polar group adjoin with polymer unit.…”

Impedance spectroscopy and conductivity studies of KCl-doped solid electrolyte

“…5. The AC conductivity of solid electrolytes is firmly dependent on the structural disorder of samples and doping procedure [36,37]. The highest conductivity for KCl-doped ionic system was obtained at higher frequency as shown in figure.…”
