| 제목 | The effect of ionic interaction on the cationic transport in polymer-in-salt solid polymer electrolyte based on PAN |
| 초록 | Solid polymer electrolytes(SPEs) based on polyacrylonitile(PAN) containing lithium or magnesium triflate[LiCF3SO3 or Mg(CF3SO3)2] was prepared to study polymer-in-salt solid polymer electrolyte system. By analyzing the fourier-transform infrared(FT-IR) spectrum, it was confirmed that ion clusters were formed with the increase of salt content and ion percolation path was formed above the critical salt concentration. And XRD measurements also indicated strong interactions between ionic species and polymer. In these systems, we investigated the roles of the salt in both salt-in-polymer system and polymer-in-salt system. At low salt concentration(in salt-in-polymer electrolytes), the salt plays as a plasticizer. On the other hand, at high salt concentration, salts make efficient percolation paths for fast cation transportation. The PAN-Li complex exhibits the highest ionic conductivity of 1.32×10-3S/cm and the PAN-Mg complex exhibits the highest ionic conductivity of 1.30×10-4S/cm at 70wt% of salt content. |
