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)/Ca 3 (PO 4 ) 2 /LiX (X = N(CF 3 SO 2 ) 2 , ClO 4 ) were analyzed by X‐ray photoelectron spectroscopy. The presence of Li 2 CO 3 /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(CF 3 SO 2 ) 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
