Solid type polymer electrolyte is in progress of research and development in many ways toimprove an ionic conductivity to attain 10-3 S/cm which is possibility of practical use of secondarylithium ion battery. There are two major methods of improving ionic conductivity; either lowering Tgof polymer or lowering the energy of ionic movement. In this work, the solid type polymer electrolyte(SPE) composites, which were composed of poly(ethylene oxide) (PEO), ethylene carbonate (EC) asa plasticizer, lithium salt, and 1-ethyl-3-methylimidazolium hexafluorophosphate (EMI-PF6) as afiller in order to improve the ion conductivity of the SPE, were prepared. The influence of EMI-PF6contents on the ionic conductivity of the SPE composites was investigated in this work. As a result,the ionic conductivity of the SPE was enhanced by an increase in EMI-PF6 content, and showed thehighest ionic conductivity at 40 wt.%. It was thought that there was a close correlation between themobility of Li+ and EMI content in a SPE composite system
