An experimental study on the effect of mesoporous silica and nanoclay addition on the ionic conductivity of poly(ethylene oxide) solid electrolytes

AC impedance spectroscopy was used to investigate the effect of mesoporous silica (SBA-15) and nanoclay (Na+-MMT) addition on the ionic conductivity of melt intercalated poly(ethylene oxide) (PEO) nanocomposites doped with lithium perchlorate. The results showed that ionic conductivity of the hybrid solid polymer electrolytes decreased with increasing nanofiller content. The results were explained based on the structure of the nanocomposites characterized by wide angle X-ray diffraction and differential scanning calorimetry
