      abstract     = {Silicon, as potential next-generation anode material for
                      high-energy lithium-ion batteries (LIBs), suffers from
                      substantial volume changes during (dis)charging, resulting
                      in continuous breakage and (re-)formation of the solid
                      electrolyte interphase (SEI), as well as from consumption of
                      electrolyte and active lithium, which negatively impacts
                      long-term performance and prevents silicon-rich anodes from
                      practical application. In this work, fluorinated phosphazene
                      compounds are investigated as electrolyte additives
                      concerning their SEI-forming ability for boosting the
                      performance of silicon oxide (SiOx)-based LIB cells. In
                      detail, the electrochemical performance of NCM523 || SiOx/C
                      pouch cells is studied, in combination with analyses
                      regarding gas evolution properties, post-mortem
                      morphological changes of the anode electrode and the SEI, as
                      well as possible electrolyte degradation. Introducing the
                      dual-additive approach in state-of-the-art electrolytes
                      leads to synergistic effects between fluoroethylene
                      carbonate and hexafluorocyclotriphosphazene-derivatives
                      (HFPN), as well as enhanced electrochemical performance. The
                      formation of a more effective SEI and increased electrolyte
                      stabilization improves lifetime and results in an overall
                      lower cell impedance. Furthermore, gas chromatography-mass
                      spectrometry measurements of the aged electrolyte with
                      HFPN-derivatives as an additive compound show suppressed
                      ethylene carbonate and ethyl methyl carbonate decomposition,
                      as well as reduced trans-esterification and oligomerization
                      products in the aged electrolyte.},
