Contribution of polyoxyethylene macromonomer additions to solid polymer electrolytes studied by complex impedance spectroscopy
The behaviour of solid polymer electrolytes based on the use of polyethylene oxide (PEO) and a lithium salt greatly depend on the recrystallisation of polymer chains. The recrystallistion rate can be reduced by the realisation of interpenetrated polymeric PEO networks. The complex impedance analysis of films shows that the ionic processes of conduction and transfer at electrode interfaces are governed by the amorphous phase content of the electrolyte. This latter can be modified by the macromonomer content.
