      abstract     = {The tris(trimethylsilyl) phosphite (TMSPi) is considered as
                      an ideal electrolyte additive for lithium ion batteries. In
                      this work, its positive effect as well as its failure
                      mechanism in a LiPF6 containing electrolyte was studied by
                      means of selected electrochemical, structural and analytical
                      techniques. The LiNi0.5Co0.2Mn0.3O2/graphite cells with
                      TMSPi as electrolyte additive were cycled between 2.8 and
                      4.6 V. Thanks to the compact cathode electrolyte interphase
                      formed by the oxidative decomposition of TMSPi in a freshly
                      prepared TMSPi containing electrolyte, both the discharge
                      capacity and the cycling stability of cells were enhanced.
                      However, our results also show that TMSPi actually reacts
                      with LiPF6 at room temperature. TMSPi is consumed by this
                      spontaneous reaction after aging for certain time. In
                      addition, a part of the fluorophosphates, generated from the
                      hydrolysis of LiPF6, is bonded to one or two TMS groups,
                      causing a decrease in the fluorophosphate content in the CEI
                      film. Consequently, the cycling stability of the lithium ion
                      cells with aged TMSPi containing electrolyte deteriorates.
                      The obtained results offer important insights into the
                      practical application of TMSPi, which means that TMSPi can
                      only be used as an effective additive in a freshly prepared
                      LiPF6 containing electrolyte.},
