In this paper is reported an investigation on the stability of the interface formed by polyethene oxide (PEO)-based polymer electrolytes in contact with lithium metal anodes. In particular, the investigation was oriented to determine the effect of the composite electrolyte preparation procedure and environment and the filler addition as well as the cell assembly procedure on the interfacial properties of PEO-LiCF3SO3/Li half cells. The stability investigation was performed at the operative temperature (90 °C) of the electrolyte (PEO20LiCF3SO3) in rest condition as well as during continuous lithium plating/stripping cycles. The results indicate that the preparation procedure and the environment play major roles with respect to the addition of the filler.
