摘要：Polyethylene oxide (PEO) based electrolytes are used as electrolyte materials for Li-ion batteries.[PEO+LiClO4] solid polymer electrolyte films were prepared by solution casting method using methanol as a solvent.The structural and thermal properties were studied by XRD and DSC techniques. XRD and DSC results revels thatdegree of crystallinity is decreases on loading of salt content into the polymer host. Temperature dependence ofconductivity plots of SPE films follows Arrhenius equation. Impedance spectroscopic studies were carried out as afunction of frequency and temperature using Hioki LCR Hitester. The dielectric properties were studied using thecomplex dielectric permittivity spectra of the SPE films. It is observed that magnitude of dielectric permittivity is highin the lower frequency region due to electrode polarization (EP) effect. The dielectric permittivity and loss wereincreased with increase of temperature
