Abstract

An analysis of the interface developed between lithium metal and poly(ethylene oxide) (PEO)-lithium bis(perfluoroethysulfonyl)imide (LiBETI) electrolytes was studied. The studies were performed as a function of polymer electrolyte salt concentration and temperature both in rest and in kinetic conditions by means of impedance measurements and galvanostatic tests, respectively. The results showed that low salt concentration P(EO)nLiBETI polymer electrolytes are good candidates for lithium-dry polymer batteries operating at medium-high temperature (60-90 °C).
