Abstract
UV-cured polymer electrolytes were prepared based on polyethylene glycol diacrylate (PEGDA). A series of PEGDA was complexed with lithium triflate salt and the effect of chain length of PEG on the ionic conductivity was studied at various salt concentration. The highest ionic conductivity at room temperature was 1.7 × 10−5 S/cm for 14 EGDA at the [EO]/[Li+] mole ratio of 8 which resulted from the balance between the number of total charge carriers and hindered mobility of polymer chain. Cyclic voltammogram for polypyrrole/PEGDA electrolyte/Li foil cell showed a pair of sharp redox peaks even at room temperature.
