Abstract

The surface layer and elemental composition of a lithium-metal electrode before and after in contact with nanocomposite polymer electrolytes (NCPEs) comprising poly(ethylene oxide)/Ca3(PO4)2/LiX (X = N(CF3SO2)2, ClO4) were analyzed by X-ray photoelectron spectroscopy. The presence of Li2CO3/LiOH in the outer layer of the native film was identified. The formation of LiF was detected on lithium surface when in contact with NCPE containing LiN(CF3SO2)2 and is attributed to the reaction between the native film and impurities. Li/NCPE/Li symmetric cells were assembled, and the thickness of the solid electrolyte interface as a function of time was analyzed at 60°C. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
