      abstract     = {Room temperature ionic liquids (RTILs), especially
                      pyrrolidinium based RTILs with
                      bis(trifluoromethane-sulfonyl)imide (TFSI) as counterion,
                      are frequently proposed as promising electrolyte component
                      candidates thanks to their high thermal as well as high
                      oxidation stability. In order to avoid a resource intensive
                      experimental approach, mainly based on trial and error
                      experiments, a computational screening method for
                      pre-selecting suitable candidate molecules was adopted and
                      three homologous series compounds were synthesized by
                      modifying the cation structure of pyrrolidinium RTILs. The
                      obtained high purity RTILs: methyl-methylcarboxymethyl
                      pyrrolidinium TFSI (MMMPyrTFSI), methyl-ethylcarboxymethyl
                      pyrrolidinium TFSI (MEMPyrTFSI) and
                      methylpropylcarboxymethyl pyrrolidinium TFSI (MPMPyrTFSI)
                      revealed excellent thermal stabilities higher than 300 °C.
                      Furthermore, MMMPyrTFSI and MPMPyrTFSI exhibit high
                      oxidation stability up to 5.4 V vs. Li/Li+. No aluminum
                      corrosion of current collector was observed at 5 V vs.
                      Li/Li+. In addition to that, these RTILs display a superior
                      salt (LiTFSI) solubility (3.0–3.5 M), compared to the
                      unmodified RTIL 1-butyl-1-methylpyrrolidinium TFSI
                      (Pyr14TFSI) (1.5–2.0 M) at room temperature. All these
                      properties make novel ester modified RTILs promising and
                      interesting candidates for application in rechargeable
                      lithium batteries.},
