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.},
