Beschreibung
Zusammenfassung:	Nanocomposite polymer electrolytes based on poly (ethylene) glycol (PEG) complexed with lithium perchlorate (LiClO4) salt and SrBi4Ti4O15 (SBT), a ferroelectric ceramic material, as filler are prepared and characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR), differential thermal analysis (DTA) and impedance spectroscopic techniques. An enhancement in conductivity is observed with the addition of SBT as filler to the PEG: LiClO4 salt complex. The PEG: 1.O(LiC1O4) + 12.5 SBT (ball-milled) polymer nanocomposite exhibits maximum room temperature conductivity of 2.4320 x 10-6 S cm 1.
