      abstract     = {Three phosphorus containing molecules,
                      tris(2,2,3,3,3-pentafluoropropyl) phosphate (5F-TPrP),
                      tris(1,1,1,3,3,3-hexafluoropropan-2-yl) phosphate (HFiP) and
                      tris(1,1,1,3,3,3-hexafluoropropan-2-yl) phosphite (THFPP),
                      were investigated as high voltage and flame retardant
                      electrolyte additives for lithium ion batteries. The effect
                      of the oxidation state of the phosphorus atom as well as the
                      influence of branched vs. linear fluorinated propyl groups
                      were investigated regarding cycling performance and
                      flammability of the resulting electrolyte. In the case of a
                      high voltage battery application, all three investigated
                      molecules showed an improvement regarding the cycling
                      performance in NCM111/Li half-cells. Post mortem analysis of
                      the NCM111 electrodes via SEM and XPS indicates that the
                      different groups of two phosphates (5F-TPrP vs. HFiP) have
                      an impact on the thickness, morphology and composition of
                      the cathode electrolyte interphase (CEI). If the electrolyte
                      formulation contains the linear side group (5F-TPrP), the
                      thickness of the CEI increases, whereas for the branched
                      group (HFiP) it decreases compared to the CEI formed in 1 M
                      LiPF6 EC:DEC (1:1) used as reference electrolyte.
                      Furthermore, addition of at least 20 $wt.\%$ of 5F-TPrP to
                      the reference electrolyte formulation resulted in a
                      non-flammable electrolyte formulation.},
