      abstract     = {The quantification of lithium ion battery electrolyte
                      additives provides challenges in terms of methods and
                      instrumentation. In this work, the detectability of the
                      flame retardant additive tris(2,2,2-trifluoroethyl)
                      phosphite (TTFPi) differs unusually when added to a standard
                      electrolyte (1 M LiPF6 in ethylene carbonate (EC)[thin space
                      (1/6-em)]:[thin space (1/6-em)]dimethyl carbonate (DMC)
                      1[thin space (1/6-em)]:[thin space (1/6-em)]1 $wt\%)$ using
                      gas chromatography with a flame ionization detector
                      (GC-FID). In this work, nuclear magnetic resonance (NMR),
                      ion trap time of flight mass spectrometry (IT-TOF™ MS) and
                      gas chromatography-mass spectrometry (GC-MS) are used to
                      investigate a pure TTFPi solution and a standard battery
                      electrolyte with TTFPi as an additive with regard to
                      parasitic TTFPi consuming reactions and different TTFPi
                      concentrations, respectively. NMR and IT-TOF™ MS
                      measurements confirm the chemical stability of the
                      TTFPi/standard electrolyte mixture and concentration
                      dependent GC-MS and GC-FID experiments indicate a premature
                      FID saturation limit for TTFPi in presence of standard
                      electrolyte. The findings explain the counterintuitive
                      absence of TTFPi for higher concentrations and provide
                      important information for future sample preparation.},
