abstract = {The stability of 1-methyl-1-propylpyrrolidinium
bis(trifluoromethanesulfonyl) imide (PYR13TFSI),
1-methyl-1-propylpyrrolidinium bis(fluorosulfonyl) imide
(PYR13FSI), 1-butyl-1-methylpyrrolidinium
bis(trifluoromethanesulfonyl) imide (PYR14TFSI) and
1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)
imide (EMIM TFSI) ionic liquids (ILs) at different
temperatures (room temperature and 95 °C) was investigated
by ion chromatography (IC) hyphenated to a mass
spectrometer. The degradation of the cations can be
summarized in the following way: The side chain of the main
molecule cleaves and reacts subsequently with the main
cation molecule to new decomposition products. In addition,
the results show that at elevated temperatures more
decomposition products are formed.The influence of Li+
cation based electrolyte salts, lithium hexafluorophosphate
(LiPF6), lithium bis(trifluoromethanesulfonyl) imide
(LiTFSI) and lithium perchlorate (LiClO4), on the
decomposition of the ionic liquids was analyzed over a long
term stability study at room temperature and 60 °C. It was
found out that in the mixtures of ILs and electrolyte salt,
the same decomposition products were formed like in the pure
ILs at the same temperature. Accordingly, there is no
influence of the electrolyte salts on the decomposition
behavior of the IL cation. The influence of the counter
anion on the decomposition of PYR13+ was analyzed as well.
It was observed that different decomposition products were
detected for PYR13TFSI and PYR13FSI.},
