Recently, polymer lithium batteries are being actively developed by many research groups, and they are in constant search of a novel polymer electrolyte, High specific energy and a safe operation, a flexibility in packaging, and low cost of processing are the characteristics sought in a polymer electrolyte for uses in lithium batteries. In this work, the polymeric electrolyte composites (PECs) based on poly(ethylene oxide) (PEO) and organic materials-modifed montmorillonite (O-MMT) clay were prepared. For an improvement of ion transfer behaviors, the native sodium cations in MMT were exchanged for different types of cations. The ionic conductivity was enhanced with increasing filler contents due to the immobile MMT clay serving as the anion species and the decreased crystallinity of PEO. The effect of modified clay on the single ion conducting behaviors and the structural properties were also discussed. |
