    Abstract: The characteristics of solid polymer electrolyte ,formed
    by complexes of poly( ethylene oxide) PEO and lithium
    perchlorate LiCL04 in various molar ratio of salt to polymer
    repeat unit with various level of plasticizer doppant diglyme
    have been investigted. The structure for complexes of PEO
    with LiCL04 is presented ,based on infrared spectroscopic
    studies. Morphology of PEO-LiCL04 solid polymer
    electrolyte was examinated by scanning electron microscopy.
    The crystallinity and phase-transition prperties have been
    investigated by using thermal gravimetric analysis and
    differential scanning calorimetry. The rasults based on electric
    conductivity measurements show that two ion-transport
    mechanisms are proposed for ion-transport in PEO-LiCL04
    complexes. The intrahelical hopping process exhibit Arrhenius
    behavior is predominant in the higher temperature range. The
    difusion of ions in amorphous phase when T>Tg is obey the
    Vogel-Tamann-Fulcher model. The electric conductivity of
    PEO-LiCL04 polymer electrolyte is 4.40x lO's Scm·1 at room
    temperature with activation energy of 0.14 ±0.006eV.
