      abstract     = {Organofluorophosphates (OFPs) are one of the major concerns
                      regarding the safety of Lithium Ion Batteries (LIBs) due to
                      their neurotoxic properties. The formation through the
                      hydrolysis of the conducting salt LiPF6 and subsequent
                      reactions (reductive/oxidative) with the cyclic and linear
                      carbonates is a major drawback in terms of commercial
                      application of LIBs. The additive Lithium Difluorophosphate,
                      which is literature known and beneficial for high-voltage
                      LIBs due to its transition metal (TM) capturing abilities,
                      accelerates the formation of toxic OFPs even further as it
                      also is a hydrolysis product of LiPF6. The suppression of
                      the formation of toxic OFPs through a synergetic dual
                      additive approach with fluoroethylene carbonate (FEC) is
                      presented in this study. Here, the thermal- and
                      electrochemical formation of OFPs are successfully inhibited
                      with the addition of 2 $wt.\%$ of FEC to the electrolyte
                      containing LiDFP (1 $wt.\%).$ Characterization of OFPs is
                      conducted via high performance liquid chromatography mass
                      spectrometry and the toxicological capabilities of the aged
                      electrolyte is assed through an inhibition-evaluation of
                      Acetylcholinesterase lyophilizate. Combined, these two
                      methods illustrate the successful inhibition of OFP
                      formation in FEC/LiDFP dual-additive electrolytes. Further,
                      this dual-additive approach does not deteriorate the
                      performance of LiDFP as single additive making the FEC/LiDFP
                      additive combination a possible new benchmark for
                      high-voltage LIBs.},
