Back Cover: Quaternary polymer electrolytes, containing PEO, LiTFSI, ionic liquid and ceramic filler, show higher limiting current density, conductivity and improved cycling performance in lithium metal/solid polymer electrolyte/LiFePO4 cells with respect to ternary electrolytes with either ionic liquid or ceramic filler. Further details can be found in the article by V. Sharova, G.-T. Kim, G. A. Giffin, A. Lex-Balducci,* and S. Passerini* on page 1188.
Keywords: ceramic fillers; electrochemistry; ionic liquids; lithium polymer batteries; polyethers.
