abstract = {In this study, the lithium ion battery (LIB) additive
1,3-propane sultone (PS) was investigated using capillary
electrophoresis (CE) connected to a quadrupole
time-of-flight mass spectrometer (Q-TOF MS). In the first
part, PS was thermally aged with the organophosphates
dimethyl phosphate (DMP), diethyl phosphate (DEP) or
triethyl phosphate (TEP) at 60 °C for one month. It was
observed that PS reacted with traces of water, with
organophosphates, with decomposition products of the
organophosphates and polymerized to long-chain decomposition
products. Due to the large number of in part similar
decomposition products, it was not possible to baseline
separate them from each other. The structures of the
decomposition products were identified and the deviations of
the detected m/z-ratios of the decomposition products to the
calculated m/z-ratios were lower than 3.0 ppm. Moreover, one
of the most interesting aspects was the formation of DEP in
the aged samples of TEP and PS. In the second part, PS was
mixed with DMP, DEP or TEP in the LIB electrolyte and aged
at 60 °C for one month. In these samples, decomposition
products were determined, formed by reaction of PS with
carbonates, organophosphates and DMP, DEP or TEP. In these
electropherograms, the decomposition products were baseline
separated.In this study, the high reactivity of PS with
different electrolyte compounds from the electrolyte was
shown in battery research for the first time.},
