Influence Of Solvent

Solid polymer electrolytes (SPEs) based on poly (vinyl alcohol) were prepared with dimethyl sulfoxide as a solvent. Prepared SPEs form the 'fast cationic transport process' and lithium ion hopping through 'fast cationic transport process' is occurred. In this study, we observed the dependence of ionic conductivity on the drying time of solvent and there was particular relationship between ionic conductivity and the amount of residual solvent. Especially, we investigated the influence of solvent on cation mobility in the ‘fast cationic transport process’ and we found that the solvent acted as a bridge to connect neighboring ion aggregates and made the ion hopping easy.
