摘要 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.
