摘要: Improvement of electrical conductivity poly ethylene oxide (PEO)–LiI polymer electrolytes is necessary for their use in solid state lithium ion battery. In this study a new kind PEO–LiI-based embedded with CdO nanoparticles improved has been prepared and characterized. The electron microscopic studies confirm that average size 2.5 nm are dispersed the PEO matrix. glass transition temperature PEO–LiI electrolyte decreases introduction nanoparticle X-ray diffraction, microscopic, differential scanning calorimetry show amorphous phase increases increase maximum 0.10 wt% doping. sample by three orders magnitude than electrolyte. exhibits VTF behavior reciprocal indicating strong coupling between ionic chain segmental motions.
