Abstract

Solid type polymer electrolyte is in progress of research and development in many ways to improve an ionic conductivity to attain 10^-3 S/cm which is possibility of practical use of secondary lithium ion battery. There are two major methods of improving ionic conductivity; either lowering T _g of 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) as a plasticizer, lithium salt, and 1-ethyl-3-methylimidazolium hexafluorophosphate (EMI-PF₆) as a filler in order to improve the ion conductivity of the SPE, were prepared. The influence of EMI-PF₆ contents 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 the highest ionic conductivity at 40 wt.%. It was thought that there was a close correlation between the mobility of Li⁺ and EMI content in a SPE composite system.
