Abstract
In this manuscript we announce new type of "tailored" imidazole-derived salts designed. synthesized and tested for application in lithium conductive electrolytes. Basic characterization of the structure of described materials has been made by Raman, IR and NMR ((13)C NMR, (19)F NMR) techniques. DSC and CV studies showed thermal stability of all salts over 200 degrees C and electrochemical stability in liquid and solid polymer solvents up to +4.6 V vs. metallic lithium anode and Al collectors. Such properties proved applicability of these salts as lithium electrolytes for modern types of lithium ion batteries. (C) 2009 Elsevier Ltd.
