A novel ionic liquid, never reported in literature until now, was properly designed, synthesized and preliminary investigated. This material was prepared combining the N-methylpyrrolidinium cation (PYR1(2S1))(+), exhibiting a sulfur atom in the alkyl side chain, with the bis(trifluoromethanesulfonyl)imide anion, (TFSI)(-), to be addressed as safer electrolyte component for sulfur -based battery systems. The presence of sulfur within the cation side chain was found to prevent the crystallization of the ionic liquid even in the presence of lithium salt. Cyclic voltammetries have clearly indicated that Li+ cation exhibits good mobility and is reversibly plated/stripped in PYR1(2S1)TFSI-LiTFSI electrolytes with high efficiency. (C) 2015 Elsevier B.V.
