PVdF-Clay Nanocomposite Gel Polymer Electrolytes For Li-Ion Batteries

摘要

In the present work, nanocomposite polymer electrolytes based on intercalation of PVdF polymer into the galleries of organically modified montmorillonite (MMT) clays has been investigated. XRD and TEM results display the formation of partially exfoliated nanocomposites. Ac impedance analysis reveal that the ionic conductivity of the nanocomposite gel polymer electrolytes increases with the increase in clay loading and attains a maximum value of 2.3 X 10~(-3) S/cm for 4 wt. percent clay loading at room temperature.
