abstract = {The state-of-the-art electrolyte in lithium ion battery
application is composed of a solvent mixture of organic
carbonates and lithium hexafluorophosphate (LiPF6) as the
conducting salt. Decomposition reactions of the
hexafluorophosphate anion with the organic carbonates and
trace amounts of water in the system result in a large
variety of organofluorophosphates. The toxicity of
organofluorophosphates has been known for some time and is
now drawing interest in the battery research context.
Molecular standards are not available as these compounds are
supposedly highly toxic, generally unknown or just recently
described. Therefore, in this study, the organophosphates
formed were investigated with gas chromatography-inductively
coupled plasma-sector field-mass spectrometry
(GC-ICP-SF-MS). With this setup, it was possible to overcome
the need for molecular standards and to perform
quantification after separation of species using only one
external standard. Comprehensive data of the phosphorus
signals were evaluated in different resolution modes (R >
300 and R > 4000) and under different plasma conditions (wet
and dry). Thereby, possible interferences originating from
aerosol entry, GC solvents, sample matrix or decomposition
products could be detected and evaluated. The developed
phosphorus speciation procedures and tuning techniques were
interrelated. Detection and quantification limits were
determined for all setups and additionally, preliminary
qualitative and quantitative investigations of different
commercially available electrolytes after thermal treatment
are presented.},
