Abstract
A new Lewis-base ionic liquid (IL) based on mono-charged 1,4-diazabicyclo[2.2.2]octane (dabco) was synthesized and its thermal and electrochemical behaviour was characterized. The dabco-based IL with bis(trifluoromethanesulfonyl)amide (TFSA) anion melts at 76 °C when the N-substituted alkyl chain length is 2. The dabco-based IL showed a wide electrochemical window of over 4 V ranging from -3.5 to +1.5 V vs. Fc/Fc + and was able to deposit and strip lithium from a nickel substrate at reasonable efficiency. © 2006 Elsevier B.V.
