A lithium sulfonated styrene oligomer ionomers were synthesized. Blend of this ionomers was formed with PEO and the effects of temperature and low molecular weight PEG as a plasticizer on ionic conductivity were investigated. This is a new type of single ion conductor. The anion units in this blend are immobile compared with cations. The room temperature conductivity was found to be 1.38×10-8 S/cm at EO/Li=1.8. By adding the low molecular weight PEG, the crystallinity was reduced, and the room temperature conductivity was enhanced to 2.25×10-5 S/cm. It has been found that this material is a new type of ionic conductive polymer, characterized by a sigle-ion transport mechanism and appropriate mechanical properties.
