| 제목 | Investigation of Solvent Effect in the Fast Cationic Transport Process of Poly (vinyl alcohol)-based Solid Polymer Electrolytes |
| 초록 | Ion-conducting polymer electrolytes based on poly (vinyl alcohol) (PVA) were prepared with dimethyl sulfoxide (DMSO) as a solvent and LiCF3SO3 as a salt to overcome low ionic conductivity and to obtain good physical properties. It was known that the 'fast cationic transport process' arisen from network-like connected large ion aggregates was formed at about 50wt% of salt concentration and then cations could move by ion hopping through the 'fast cationic transport process'. Especially, we could observe the dependence of ionic conductivity on the drying time in relation to the amount of existing solvent in SPEs containing 50 and 80wt% of salts. In this study, therefore, we investigated the influence of solvent on cation mobility in the fast cationic transport process by FTIR, XRD and ac impedance spectroscopy measurement. |
