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 ( 13C NMR, 19F NMR) techniques. DSC and CV studies showed thermal stability of all salts over 200 °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.
